@@J3DTech OK, let me be more specific: The time and effort you put into making this video so thorough yet concise and extremely informative was totally worth it!
Thanks for breaking apart the Ultra and showing the internals. We could only get a top-down view. We decided to delist the Ultras from our store until we hear from Uniformation.
I have run a factory, and in part of my life, my experience with situations like this is that it was a decision that wasmade was most likey based on supply chain issues, not trying to save money-the cost of changing out a manufacturing line is significant and not taken to save a small amount per unit so late in the release cycle.
I agree. This seems like a critical supplier increased price without warning or became unable to produce the part at acceptable quality without notice. This would put Uniformation in a very difficult position. However, Uniformation's communication has been typical of a Chinese business and unfortunately, woefully inadequate. I hope they fix their issues. The CEO needs to reflect on whether he's still capable of the role. FWIW I'm an exec at a global logistics company and we see stuff like this happen from time to time with our clients. It's difficult for everyone.
Thanks for going through the tech side of this, incredible video covering the situation. I'm interested to see what they say to me before i put my video back online.
Hi @FauxHammer. I was always extremely skeptical of any TH-cam reviewers, and I think me and you had a clash about it some time ago, when I wrongly accused you. I just wanted to make sure I let you know that you are really gaining massive amounts of credibility in my eyes all the time, especially now, when I remember you were very outspoken about Uniformation and GKTwo. Just kudos dude, nice to know there is somone that is trustworthy and credible. Thank you.
@@xixipli thank you. I have been getting accused a lot of this lately. And I am very conscious of my own arrogance and coming across as some kind of shill. I’m just a miniature printer with a tech background that says what he thinks about machines. I’ve had opportunities to do “promotional” videos (like, announcement content like the gk3 ultra) and have been very clear when this was the case But my aim. My only aim, is for people to understand what they are paying for and I hope it helps them. And I greatly appreciate you telling me you’ve come around. Thank you. I’m here to work for you guys. Sorry if we clashed. I’m soft skinned
@@FauxHammer No one's accused or is accusing you of being a shill, cut the drama - and that's the main issue with you, "hurt feelings" and "drama". You're a "tryhard" and "wannabe" "Resin 3D printer/printing" hotshot, but you aren't, really. You ARE an excellent presenter, and producer of high production value videos (great high-detail photography), you DO extremely thoroughly visually cover the 3D printers and print results from the printers that companies send you for free and your only compensation is from affiliate links, in enough detail that someone who _actually knows what they're looking at and what to look_ for can make an informed decision regarding the qualities or lack thereof of the unit you're covering in a video. No rational person would make concrete, objective critique of some particular(s) in your hyperbolic uninformed, ignorant nonsense (what you perceive as hurtful comments personally attacking your character and generally gleefully block) to you on your TH-cam channel. Filtering out certain comments you allege existed that are psychotic threats to you and your loved ones is one thing (and a police matter) - filtering out legitimate technical corrections to outrageously flawed statements you make about some technical matter or other should be welcomed by someone who wants to achieve his goal as a "3D resin printer authority", by actually becoming one based on knowledge and experience and not just because you wish you were long enough and hard enough like in the Disney movies. Not exaggerating (borderline lying) about your "technical background" would be key, anyone can find out easily that your background is in sales (and you're obviously an outstanding visual media presenter), and those actually skilled in the technical arts can see even more easily that you shamelessly hardly know what you're talking about in technical areas in any meaningful way. Some constructive advice to you - keep doing what you're extremely good at, and work hard to actually get good at what you want to be good at, if you genuinely have the aptitude and ability for it, and if not, recognize it and work to your strengths instead of pretending to be strong in your weaknesses and making an spectacle of your emotional lability - serious people dgaf about your or anyone else's personality disorders. Also, you're not being "singled out" here, YOU chose to put yourself into the public eye, YOU chase after growing your audience and influence (which you seem to be succeeding at), you should realize that the saying, "if you want to make an omelet you have to break some eggs" is accurate and true and maybe some of those eggs will be yours occasionally, it goes with what you're engaging in. The ONLY reason I spent the time and effort making this comment is because you have "reach" and are such a good presenter, you have the potential to actually be one of the contributors positive changes in consumer 3D resin printing if you correct or at least control your deficiencies, instead of ending up as just another drama show with a weirdo host displaying his uninteresting, unfortunately not particularly unique or even interesting personality disorders for hundreds of thousands to be entertained (or not) by.
I think you hit it right on the head. Without more A/B testing against a unit that has the correct rail system, it's really hard to tell what the actual impact is. Which, at the end of the day, is the most important thing to me. That said, I've had so much trouble getting successful and acceptable quality prints out of my unit, it's very hard to tell if any more fixes or changes would even matter. So far I have: - Replaced the build plate (warped) with another (less warped). - Sanded flat the OG build plate, which has gotten me the most repeatable successful prints (not falling off the build plate) - Replaced the leveling block - Stopped using the auto-feed system, due to so many others having leaks. - Replaced the cracked cover. - Re-seated about half of the heat-set threads in the vat, because when I changed the nFEP, several of them were jammed into the steel "ring" that the nFEP is sandwiched between, and when I pulled out the nFEP, they pulled out of the vat. This doesn't include returning the wash station because it dumped a liter of IPA all over my workspace before I noticed the tanks were leaking. Oh, and the mount in the wash station was wobbling all over when I rec'd it, so I had to take it apart and tighten all of the screws.
@@JerryBWagoner I hadn't seen any posts about it at all. If I hadn't been doing the nFEP change so late in the evening and in a rush, I would have taken pictures and put up a post about it. But now I'm worried that even after re-setting the inserts (used a soldering iron) that there might be some leakage from the vat. The silicon gasket that goes between the nFEP bracket and the vat didn't leave me with a lot of faith that it'll be enough. I've only had one other resin printer, a Saturn 3 (not ultra), but the metal construction of the vat, and the bracket that holds the nFEP sheet, and where that bracket screws onto the vat felt VERY secure and I had no concerns or leaks. This one just felt...not great.
There were two revisions of the GK 3 Ultra initially, officially depending on the ball screw pitch: 1204 then 1205. But was it only about the ball screw type? Confirmed by many testimonies already: no 1205 unit has linear rails. To be sure (don't trust anything Uniformation claims, at this point) please find someone who has an early 1204 unit to confirm if those had linear rails. If that's the case, this would demonstrate that Uniformation sent earlier units (including to the YT testers…) according to specs, with linear rails; then switched their production line to the lower cost "1205" version silently crippled from the rails, while publicly tricking everyone with the ball screw pitch claim being the main reason for the revision change. The FB group shows that almost nobody (I didn't see anyone yet) got the 1204 version, so TBD.
@@FauxHammer So, as far as we know so far, there has never been a single GK 3 Ultra unit with linear rails, apart from the imaginary advertising text and images on their website (which are still there as I write this!). Amazing. I am speechless.
This makes the most sense, as their brand was built on rock solid machines and great support. Despite the lemons shipping out, their support team has tried to be as helpful and forthright as is reasonable. I've lost patience with my machine and want a return. I could buy 2 Anycubic M7's or Elegoo Saturn 4 16Ks. I just need printers that work.
Wow, I was wondering why I seem to get inconsistent layer stacking on my ultra... As it prints up the Z axis I sometimes get slight shifting in the X and Y axis that makes prints look horrible. This is shocking. This whole ultra situation has been a nightmare and is honestly as a gamer this is the perfect reminder why we PRE-ORDER NOTHING.
Makes complete sense to replace 4 pcs cheaper rails with 2 pcs integrated solution for more money and save on assembly, improve rigidness and most important - function. As stated at 4:26 dual rail assembly was causing inconsistent printing effect. Although dual rail is cheaper as a part, it might be costly to factory calibrate.
But the problem is thats not true. Dual Rails are in reality more expensive than this single rail system. So the CEO might have gotten duped by a bad quote, swapping a more expensive solution to a cheaper one, but paying more and getting 2 contact points instead of 8.
@@Sandermander Might be. Just saying it is believable. I would believe either way, since I was recently looking for linear rails for my diy CNC build. Pricing doesn't make much sense, it is all over the place. I guess QC and tolerances are what you pay the most. It can go for 30 eur or 300 eur for same size.
My main point is that this system seems to will not uphold over time.. more so if you use the printer for big parts, there will be a stronger wear then on two-rails + ball screw system. i need a big printer for big parts, but its to expensive if the printer stops working reliable after e.g. 12 months..
I have a 1205 without dual rails and all my prints have been large and perfect. Maybe the manufacturing quality of the single rail system is inconsistent. I would want the dual rails if they sent them out b/c that's what I paid for and prints may be more crisp; I have no way to know. We need to know why people with 1205s are getting layer lines they can't eliminate. And a comparison of prints between a 1204 and a 1205 would be helpful.
First time ive ever pre-ordered a product and this is exactly why. Bought day 1 and didnt receive until Nov 30th. Fortunately I've been lucky with mine and have seemingly none of the common issues many others have had. However this is just another kick in the balls considering this thing was so expensive...
Nice to see a detailed video that doesnt include 'this was given to me for free', a consumer opinion varies greatly from someone who isnt out of pocket. In mind of Uniformation mistakes are there to be learned from, they didnt use consumers as a beta test for the product they genuinely thought they were opting for a better option but turned out to be a turkey. They have admitted this and are willing to make up for it.
@@Nonprofessional_Tinkerer It is actually for this very reason that I try to purchase every 3D printer that I review. I have at this point over 22 resin 3D printers. Three of them were sent to me for free. I've only done a review on one of them. And that was the M7 Max. And that's because that was sent to me not to do review. It just showed up on my doorstep and a cubic said hey, this printer is actually built based on all the feedback you've given to us over the last few years and the feedback that I gave them when I was in China about a year and a half ago. We want you to give us any additional feedback on this pre-production unit before we go into full production. Turned out that my production unit was going to be the full production aside from the software which was slightly different, but at this point my software is the same as everybody else's.
@@J3DTech Offtopic, but with that knowledge in your pocket, do you know if they plan to release a higher resolution version ? Seems a no-brainer to do a 14k M7 Max :)
The amount of weight you are putting on build plate mounting arm to push down is way more than the weight of the build plate. Seems like you are fighting the internal resistance of the motor which is then putting a huge deflection on that arm causing that binding. You are right...not scientific at all.
Yep not at all! We know that a printer of this size will get 50-65KG of resistance when in use. We have data on 10" printers that are getting over 50kg.
Swapping out the rail system might require machine work to the base and/or compromise the base. It could be that the design of the base and rail system is integrated, which would require basically a replacement of the whole system.
Real issue. It isn't a reduced quality of prints but rather completely destroyed prints with many visible layer lines and other artifacts. A 16k screen for quality yet it looks like a 720p quality prints. UPS picked up my printer the day before this video for return as it was the worst printer I've ever owned yet the overall design of capabilities would have made this the best printer I owned and the largest of they kept their quality standards high. Uniformatiok did ask me for the data for their benefits but it goes to show how little testing they did (if any)
@@mrgunn2726 It's not theoretical originally I had a lot more content in this video where I showed prints layer lines and issues. Maybe I should have left that in but I was worried the video was getting too long.
I emailed to cancel my order. Perhaps i shouldn't be but I'm honestly worried they will have the funds necessary to refund all the customers i believe will be requesting them
Whatever the reason, Uniformation messed up hard since the GK2. First the horrendous shipping issues with the Ultra and now everything related to the GK3s. I wonder if they will recover fast from this, or other manufacturers win the race for 25. Also I don't like seeing some content creators here now and their comments is pretty...cringe to stay polite. Whatever, another good video and wonder gow things will turn out.
@@rphl-v3k Let's hope it's a good path moving forward. I made a video about uniformation but I haven't made a video about the other brands and trust me all of them have some skeletons Some of them are pretty big as well. I just don't like making this type of content. But in the end we need everybody to uplift everybody and get better. That's the only way out.
@J3DTech Great though that you inform the people on this issue. It surely will do some good...and if only it saves some people's money and time. Hope the future for resin printers will have more positivity as well!
Thank You Derek for keeping us informed! I have one and so far it has printed great, but I haven’t tried printing my big parts yet that will take a minimum of 2kg. Can you try printing something solid and heavy (2-3kg) to see how the prints come out and also print the same model on the Anycubic M7 Max? It would be interesting to see how they compare print quality wise. I don’t care about speed just print quality and accuracy. I realize the light sources are different but if the weight of the model plus the suction force of pulling up may cause layers to shift and be noticeable.
The only "problem" that I have had with mine to date is the printing plate was ever so slightly concave which was causing issues with supports in the middle of the build plate to fail. That said, Uniformation was very responsive and I was able to get a replacement part sent to me.
One thought. Nyogel 767a damping grease may be the perfect solution for the "binding" you experienced. I wonder if application of a tiny amount of that on the rails would eliminate the entire problem. There is a nearly identical issue on Thrustmaster aviation throttles which use a linear rail system and Nyogel 767a completely eliminates the problem on that platform. Something to consider! Use sparingly or it overdampens and causes issues.
I’m finding issues with the heating system …. Sort of leaving a bad taste in my mouth this whole uniformation debacle. I bought the ultra because I needed a larger build volume with a heater . Currently using the heater puts lines all over my model and now I’m seeing that the system isn’t to the spec I bought into 🤦♂️
that binding lower down will be due to poor motor alignment, if possible try loosening and tightening the motor while the carriage is low down. If it were a normal system, instead of doing this to the motor you could loosen and tighten the ball screw nut while it's low down but here with the nut and guide rails being combined you can't do that.
@@J3DTech not really did it mostly off intuition this machine is a very unique case though, like I said usually you could loosen and tighten the ball nut while it's near the motor so they are algined and not binding but yeah can't do that here so I'd try to just loosen and tighten the 4 bolts holding the motor in while the carriage is as low as you can get it without being in the way.
When I saw this I was hoping they used a good part like the Hiwin and it's much better ratings. From what I'm seeing the 6kg load is the horizontal rating, but the unit is vertical. Wonder what that rating is. Is this a recirculating ball way unit? Looks like it, but trying to verify
Man, what is with January of this year and 3D printer drama -- first I heard of issues with Bambu Labs, and now Uniformation. Totally different reasons, (Doofenschmerz) "but it's weird that it's happened twice"
I don`t understand what the problem is! Have they replaced the linear rails and ball slides with box section or dovetail section guideways? If so, why is that a bad thing? The best and most accurate CNC milling machines uses box ways, not linear rails, for accuracy and stability. It`s a system that is long proven and will last thousands of hours without wear.
First, not all are built the same. The issue is that it seems like the installed system maybe a cheaper part then what the CEO had been lead to beleive. That said I found this on practicalmachinist.com what is your take? 1. Box ways are limited in speed vs. linear guides / roller guides 2. Linear will be more accurate because they are preloaded, there is no mechanical play. Box way has to have some clearance for the oil film. 3. Linear is not subject to noticeable stick-slip common to box way. 4. Box way has better damping than linear (except roller) due to the greater amount of surface area distributing the load. 5. Linear can allow more distortion under extreme loads than will Box way if the linears are undersized for the machine. (Common problem on cheaper machines.) 6. Machine service life is longer with linear as they can be relatively easily replaced.
weeell... I agree withe don't make any sense to change to expensive solution, if wasn't for the improving the machine already. The possibility that the Uniformation was scammed. The last observation, which I think is a big piece of the puzzle, is that if I understand correctly with my third-world English, if you apply pressure on the end of the plate arm, it becomes harder to move it up or down and that it is easier to move it at the bottom than at the top and that it is also much easier to move it by applying direct force at the base where the ball screw is, I think it is because the ball screw is bending forward, changing the directions of the applied force at the pivot points. This is consistent with the fact that with the new Z-axis stabilization system, it only has 2 contact points, when the dual linear rail system has 8 in total.
Thanks for the forecast! I need some advice: I have a SafePal wallet with USDT, and I have the seed phrase. (mistake turkey blossom warfare blade until bachelor fall squeeze today flee guitar). What's the best way to send them to Binance?
Great video ! Hopefully they'll be very careful about the GK3/GK3 Pro manufacturing and release. I understand the point about the overall construction of the Z axis / top plate looking more expensive on the GK3U, but I am not certain that it's a better solution mechanically speaking, or in terms of XYZ orthogonality, than Anycubic's. What are your impressions in terms of the orthogonality and rigidity of their structural components ?
Overall not attatching the tower to the top plate will isolate the LCD. One major issue with the Saturn series is that the tower will bend the top plate. The moutning surface of this is massive and thick. This printer is heavy can (have) picked it up by the tower and there is no bend on the bottom plate at all. It's very very sturdly. I honestly would not do that same test with my M7Max. But that said the M7Max is a truly great pritner and it works very very well. I would say that GK3U is way overbuilt in this area.
When you make the next video on this printer make sure to refer to this video as well as showing some of the footage of this video in the next edit as B-Roll.
@@filipposl3128 I'm going to be involved with the Pro well more or less. I'll be keeping an eye on it to make sure it's a good answer transparent release.
Smaller ball bearings with the proper lubricant are far superior than larger ball bearings with the proper lubricant in this type of application. Larger ball bearings are used in applications that require more stress factors such as load and / or operation does not need to be as smooth. Another factor that could be concerning is the quality of those ball bearings and hard or soft material (the ball bearings) they are made out of.
So….a new additional dual rail system is now going to be fitted to new machines? We might be able to fix it, but no one knows if you can fix them yourself…..and we have to wait until someone else tried to fix it so we can know if it can be fixed. What an absolute cluster. And we have to sit around for another 2-3 weeks to find out if it’s even remotely possible to fix. Ridiculous.
@@tylarfasolt1381 I'm not sure on that one. I'm still working with their product team and the CEO on that angle. I'm still trying to get as much data as I can about this rail system. Like I said in the video, the CEO is still under the impression that this should be an upgraded system and want s more information stating that it is inferior. Like I said in the video, I have my opinions but I truly don't have any concrete data and by concrete data. I don't mean this print looks good. This print doesn't. I mean factual hard evidence that would stand up in a court of law data. I'm trying to get that And we'll go from there. But just keep in mind there is a chance that this rail system is adequate.. from my perception, it's a low chance but still there's a chance.
If you take a look at the grooves where the original rails were supposed to sit, they actively CNCed away 8mm of material on each side of the Z-tower to fit this single rail solution. Which means the "old" Dual Rail system no longer fits, making it impossible to fix without a new Z-tower for each printer.
@@J3DTech Well, you can take your calipers and simply measure 45mm out from the "groove" where the intended screwholes are off-center. You can see that 45mm rails would stick out from the aluminum now, due to the material they removed. Meaning retrofitted rails would not be considerd "stable", i don't think :)
Good video. Hard to believe they had the manufacturing change their design and them not testing it before such a major change. Or they tested it and said, it's all we got for better or worse. YEET it for consumers beware.
Selling something and delivering something else it's a no go. Yet the real question is now does this system actually perform when loaded as this printer is intended.
@@dariorseventyeight For this one I need the power of the internet to do some testing. Doing it on a single machine isn't going to be the best but if you watch to the very very end of the video you'll see I did a non-sciencey science test and mine does bind up.
So long story short... They made changes to the design based on the BELIEF of improved reliability/consistency rather than any actual preproduction R&D? It seems like they've been scrambling to recover from the delays, and made hasty decisions without appropriate part specification confirmation. Given the fact that linear rails would have had a wider tolerance induced pivot point, the system they're using would have exponentially increased variance towards the outside of the build plate for any tolerance induced movement... Seems they haven't taken this into account at all, and just said, "yep, sounds good, let's go with that"....
At the end of the video when you're applying force at the end of the build plate arm, you are creating a fulcrum scenario. I see the binding situation as normal when you apply upward and downward force away from the lead screw. The further out you move away from the screw the worse it gets and the closer you get to the screw the easier it is. Your non-scientific approach is trying to rotate about the fixed point of the arm. But the rest of your review was on point.
@@ThYr0N reach out to them and see what other options they can provide as well. I think in the end if we can get a printer that works really well for me. At least I'll be happy. Because like I stated in the video I bought this printer with my own money to have a good printer.
Contact them and if they don't want to hire a company to retrieve it from you for a refund, call your credit card company and I'm sure they'll do a charge back given the switch and bait that resulted in a lemon product. I'm sure Uniformation will want to avoid a charge back at all cost.
@@J3DTech if there is a solution, the machine is working wonders for me. BUT i've discovered that large printers have different problematics. The only thing I'm worried is endurance of the printer, is a lot of money compared with a ULTRA 16k (I know build volume not the same), but the heater is there now so..... And I'm seeing a lack of updates firmware wise, the network drive isn't working good for me also :S
@J3DTech I had to relevel GK3 ULTRA 3 times already so... One because from factory wasn't leveled, second with the new block because it was unaligned and had to do it again and some days ago I had a side of the build plate also failing (that's maybe on me for not tightening enough the block). So not really sure this auto leveled system is that reliable
man thats rough... Ive only been 3d printing for a month.. but uniformation seemed like a big guy in the race.. i ended up ordered elegoo saturn 4 ultra and am super happy. was half the price, so now i ordered two hahahah... seems like uniformation better get this under control now or theyre about to get swollowed up by another chinese competitor who is half the price....
Well that's off of my list now, it’s down to the Reflex RS or Phrozen Sonic Mega 8K unless a better option comes to light. I have a Saturn 4u but i cant get 20% of the build plate to adhere even after trying to adjust it. I am hoping to be able to start using resin printers to make consumable’s that i designed & sell for my product line instead of being at the mercy of injection mold companies who have almost tripled my price in the past 3 years. Thank you for the video although it does not help my severe analysis paralysis.
Ball screws are not designed to be driven by the load, rather they are designed to provide accuracy in linear motion under load. Setting up a dial indicator and looking at flex and repeatability in the system would be a better test overall. Does it print or is it crap vs dual rails? Accuracy and flex demonstrably different? Does it take 20 pounds of force to peel a full surface print? All the printer is doing is peeling off semi hard polymer from a relatively flexible surface. It's not a magnet. If it were 35 kg load bearing system, that is 77 pounds. Seems like overkill either way. What are peel forces in a machine of this size? I've ran a lot of CNC equipment and was always impressed at how accurate and strong, seemingly puny rails work. How long is the bearing cartridge slide, can't really tell from your presentation.
@@helicopterdriver I did have all that information but in the end cut is as I felt most people were not interested in that information. Give me a few hours and I'll add a link in the description with this information.
@@J3DTech You are right but I guess I look at things more on a technical side due to my background. I looked at a few machines recently and their products had me interested. Anything backordered is a red flag I avoid., and usually anything "first generation." Tilting vats come to mind, but we shall see where that goes. Unfortunately these days you have to actually use it to determine it's actual faults or hopefully someone like you looks at it in detail. I appreciate the information from wherever it comes. I've never thought about peel forces. Would certainly be interested know what they are for the different machines out there. Anycubic has managed to measure it and compensates retraction based on sensing the release. I've had my share of print failures from various things. Suction cupping was my first and it was not pretty. Thanks for your efforts, it is appreciated.:D
@@helicopterdriver Heygears and Concept3D (Athena) have been doing it for a while as well. I am not certain that Anycubic's solution works well, in particular the pressure sensing during retract, as my M7 seemed to blissfully ignore changes in cross sections to adjust the off time - I think that the frame of that printer is too poorly constructed to provide reliable data during the retract phase.
@@helicopterdriver On Athena, we regularly see peel forces up to 50kg on full plates with models on the plate during the initial 30 layers or so. For a machine this size, I would expect those loads to increase up to 70-80kg. So IMO this rail is inadequate for the purpose.
Here are the measurements of the Rail used. Sorry, I'm no artist.. We have Force data on a 10" printer that 50kg of forced is often hit. This being a 13" printer I think we can safly say it can peak over 60GK but I don't have that data.

@@n0f8r Depends on how they act over the next few months. If they can find a path to a well working printer it will be ok. If not... Well you know the rest. But Uniformation not existing isn't a good outcome to everyone that uses their products.
I would say the test is unfair. Putting force on what equates to a lever will cause binding at some point. If it is rated to drive smoothly with, for example, 20KG of weight, then putting that much weight on it and seeing how it moves would be more fair. Leaning on it with more force than designed will show failure when it was never meant to handle the load. I am not saying the design is good or bad, but rather suggesting a way to quantify how bad it might really be.
Great video, thanks for all the hard work that has gone into it. I have been working with them too, particularly around the GK3 Pro and all the communications between myself and Uniformation have felt genuine and good natured including when faced with issues with both machines. Which have been dealt with to the best of their ability. My take at the moment is we will have to wait and see how it pans out as at least on the surface I can’t see a fast solution here. It’s not what anyone wanted but it’s where we are.
Dude this seems like a good Desine. They went out of theyre way to make a custom Rail that seems to be well made also. I like the anycubik Printer for its rails but they are Of the shelf and need to be adjustet to be Precise.Though they are overkill....

@retromodernart4426 I think you're being way to kind but thank you!
@@J3DTech OK, let me be more specific:
The time and effort you put into making this video so thorough yet concise and extremely informative was totally worth it!
Thanks for breaking apart the Ultra and showing the internals. We could only get a top-down view. We decided to delist the Ultras from our store until we hear from Uniformation.
I have run a factory, and in part of my life, my experience with situations like this is that it was a decision that wasmade was most likey based on supply chain issues, not trying to save money-the cost of changing out a manufacturing line is significant and not taken to save a small amount per unit so late in the release cycle.
I agree. This seems like a critical supplier increased price without warning or became unable to produce the part at acceptable quality without notice. This would put Uniformation in a very difficult position. However, Uniformation's communication has been typical of a Chinese business and unfortunately, woefully inadequate. I hope they fix their issues. The CEO needs to reflect on whether he's still capable of the role. FWIW I'm an exec at a global logistics company and we see stuff like this happen from time to time with our clients. It's difficult for everyone.
Thanks for going through the tech side of this, incredible video covering the situation. I'm interested to see what they say to me before i put my video back online.
Hi @FauxHammer. I was always extremely skeptical of any TH-cam reviewers, and I think me and you had a clash about it some time ago, when I wrongly accused you. I just wanted to make sure I let you know that you are really gaining massive amounts of credibility in my eyes all the time, especially now, when I remember you were very outspoken about Uniformation and GKTwo. Just kudos dude, nice to know there is somone that is trustworthy and credible. Thank you.
@@xixipli thank you. I have been getting accused a lot of this lately. And I am very conscious of my own arrogance and coming across as some kind of shill.
I’m just a miniature printer with a tech background that says what he thinks about machines.
I’ve had opportunities to do “promotional” videos (like, announcement content like the gk3 ultra) and have been very clear when this was the case
But my aim. My only aim, is for people to understand what they are paying for and I hope it helps them.
And I greatly appreciate you telling me you’ve come around. Thank you. I’m here to work for you guys.
Sorry if we clashed. I’m soft skinned
@@FauxHammer No one's accused or is accusing you of being a shill, cut the drama - and that's the main issue with you, "hurt feelings" and "drama".
You're a "tryhard" and "wannabe" "Resin 3D printer/printing" hotshot, but you aren't, really. You ARE an excellent presenter, and producer of high production value videos (great high-detail photography), you DO extremely thoroughly visually cover the 3D printers and print results from the printers that companies send you for free and your only compensation is from affiliate links, in enough detail that someone who _actually knows what they're looking at and what to look_ for can make an informed decision regarding the qualities or lack thereof of the unit you're covering in a video.
No rational person would make concrete, objective critique of some particular(s) in your hyperbolic uninformed, ignorant nonsense (what you perceive as hurtful comments personally attacking your character and generally gleefully block) to you on your TH-cam channel. Filtering out certain comments you allege existed that are psychotic threats to you and your loved ones is one thing (and a police matter) - filtering out legitimate technical corrections to outrageously flawed statements you make about some technical matter or other should be welcomed by someone who wants to achieve his goal as a "3D resin printer authority", by actually becoming one based on knowledge and experience and not just because you wish you were long enough and hard enough like in the Disney movies.
Not exaggerating (borderline lying) about your "technical background" would be key, anyone can find out easily that your background is in sales (and you're obviously an outstanding visual media presenter), and those actually skilled in the technical arts can see even more easily that you shamelessly hardly know what you're talking about in technical areas in any meaningful way.
Some constructive advice to you - keep doing what you're extremely good at, and work hard to actually get good at what you want to be good at, if you genuinely have the aptitude and ability for it, and if not, recognize it and work to your strengths instead of pretending to be strong in your weaknesses and making an spectacle of your emotional lability - serious people dgaf about your or anyone else's personality disorders.
Also, you're not being "singled out" here, YOU chose to put yourself into the public eye, YOU chase after growing your audience and influence (which you seem to be succeeding at), you should realize that the saying, "if you want to make an omelet you have to break some eggs" is accurate and true and maybe some of those eggs will be yours occasionally, it goes with what you're engaging in.
The ONLY reason I spent the time and effort making this comment is because you have "reach" and are such a good presenter, you have the potential to actually be one of the contributors positive changes in consumer 3D resin printing if you correct or at least control your deficiencies, instead of ending up as just another drama show with a weirdo host displaying his uninteresting, unfortunately not particularly unique or even interesting personality disorders for hundreds of thousands to be entertained (or not) by.
I think you hit it right on the head. Without more A/B testing against a unit that has the correct rail system, it's really hard to tell what the actual impact is. Which, at the end of the day, is the most important thing to me.
That said, I've had so much trouble getting successful and acceptable quality prints out of my unit, it's very hard to tell if any more fixes or changes would even matter. So far I have:
- Replaced the build plate (warped) with another (less warped).
- Sanded flat the OG build plate, which has gotten me the most repeatable successful prints (not falling off the build plate)
- Replaced the leveling block
- Stopped using the auto-feed system, due to so many others having leaks.
- Replaced the cracked cover.
- Re-seated about half of the heat-set threads in the vat, because when I changed the nFEP, several of them were jammed into the steel "ring" that the nFEP is sandwiched between, and when I pulled out the nFEP, they pulled out of the vat.
This doesn't include returning the wash station because it dumped a liter of IPA all over my workspace before I noticed the tanks were leaking. Oh, and the mount in the wash station was wobbling all over when I rec'd it, so I had to take it apart and tighten all of the screws.
@@PhillFisk And it's going to take some time to get this information.. but I feel like it's the only way to he 100% sure.
I had the same exact same vat issue.
@@JerryBWagoner I hadn't seen any posts about it at all. If I hadn't been doing the nFEP change so late in the evening and in a rush, I would have taken pictures and put up a post about it. But now I'm worried that even after re-setting the inserts (used a soldering iron) that there might be some leakage from the vat. The silicon gasket that goes between the nFEP bracket and the vat didn't leave me with a lot of faith that it'll be enough.
I've only had one other resin printer, a Saturn 3 (not ultra), but the metal construction of the vat, and the bracket that holds the nFEP sheet, and where that bracket screws onto the vat felt VERY secure and I had no concerns or leaks. This one just felt...not great.
There were two revisions of the GK 3 Ultra initially, officially depending on the ball screw pitch: 1204 then 1205. But was it only about the ball screw type? Confirmed by many testimonies already: no 1205 unit has linear rails. To be sure (don't trust anything Uniformation claims, at this point) please find someone who has an early 1204 unit to confirm if those had linear rails. If that's the case, this would demonstrate that Uniformation sent earlier units (including to the YT testers…) according to specs, with linear rails; then switched their production line to the lower cost "1205" version silently crippled from the rails, while publicly tricking everyone with the ball screw pitch claim being the main reason for the revision change. The FB group shows that almost nobody (I didn't see anyone yet) got the 1204 version, so TBD.
I'm off to my storage unit later today once i finish work.
I do not have rails on mine either
@@FauxHammer Is it the pre-production version you got for testing purpose by or before July 2024? Or a later one
@@fluxcapacitorI was told it was one of the first prototypes
@@FauxHammer So, as far as we know so far, there has never been a single GK 3 Ultra unit with linear rails, apart from the imaginary advertising text and images on their website (which are still there as I write this!). Amazing. I am speechless.

@@AustinLindstrom And no one would blame you for it.
Wow, I was wondering why I seem to get inconsistent layer stacking on my ultra... As it prints up the Z axis I sometimes get slight shifting in the X and Y axis that makes prints look horrible.
This is shocking. This whole ultra situation has been a nightmare and is honestly as a gamer this is the perfect reminder why we PRE-ORDER NOTHING.
Makes complete sense to replace 4 pcs cheaper rails with 2 pcs integrated solution for more money and save on assembly, improve rigidness and most important - function. As stated at 4:26 dual rail assembly was causing inconsistent printing effect.
Although dual rail is cheaper as a part, it might be costly to factory calibrate.
@@frantzs1077 Yeah seems like finding a better factory would have been the correct choice.. but I'm not sure what the situation in China is
how much did they pay you to say that?
@@eg5909 Sorry I don't follow?
But the problem is thats not true. Dual Rails are in reality more expensive than this single rail system. So the CEO might have gotten duped by a bad quote, swapping a more expensive solution to a cheaper one, but paying more and getting 2 contact points instead of 8.
@@Sandermander Might be. Just saying it is believable.
I would believe either way, since I was recently looking for linear rails for my diy CNC build. Pricing doesn't make much sense, it is all over the place. I guess QC and tolerances are what you pay the most. It can go for 30 eur or 300 eur for same size.
My main point is that this system seems to will not uphold over time.. more so if you use the printer for big parts, there will be a stronger wear then on two-rails + ball screw system.
i need a big printer for big parts, but its to expensive if the printer stops working reliable after e.g. 12 months..
I have a 1205 without dual rails and all my prints have been large and perfect. Maybe the manufacturing quality of the single rail system is inconsistent. I would want the dual rails if they sent them out b/c that's what I paid for and prints may be more crisp; I have no way to know. We need to know why people with 1205s are getting layer lines they can't eliminate. And a comparison of prints between a 1204 and a 1205 would be helpful.

Nice to see a detailed video that doesnt include 'this was given to me for free', a consumer opinion varies greatly from someone who isnt out of pocket.

They have admitted this and are willing to make up for it.
@@Nonprofessional_Tinkerer It is actually for this very reason that I try to purchase every 3D printer that I review.
I have at this point over 22 resin 3D printers. Three of them were sent to me for free. I've only done a review on one of them.
And that was the M7 Max. And that's because that was sent to me not to do review. It just showed up on my doorstep and a cubic said hey, this printer is actually built based on all the feedback you've given to us over the last few years and the feedback that I gave them when I was in China about a year and a half ago. We want you to give us any additional feedback on this pre-production unit before we go into full production.
Turned out that my production unit was going to be the full production aside from the software which was slightly different, but at this point my software is the same as everybody else's.

@@J3DTech Offtopic, but with that knowledge in your pocket, do you know if they plan to release a higher resolution version ? Seems a no-brainer to do a 14k M7 Max :)
The amount of weight you are putting on build plate mounting arm to push down is way more than the weight of the build plate. Seems like you are fighting the internal resistance of the motor which is then putting a huge deflection on that arm causing that binding. You are right...not scientific at all.
Yep not at all! We know that a printer of this size will get 50-65KG of resistance when in use. We have data on 10" printers that are getting over 50kg.
Swapping out the rail system might require machine work to the base and/or compromise the base.
It could be that the design of the base and rail system is integrated, which would require basically a replacement of the whole system.
I am not sure I understood how this impacts print quality, is it just a theoretical issue if you print large heavy parts?
Real issue. It isn't a reduced quality of prints but rather completely destroyed prints with many visible layer lines and other artifacts.
A 16k screen for quality yet it looks like a 720p quality prints.
UPS picked up my printer the day before this video for return as it was the worst printer I've ever owned yet the overall design of capabilities would have made this the best printer I owned and the largest of they kept their quality standards high.
Uniformatiok did ask me for the data for their benefits but it goes to show how little testing they did (if any)
@@mrgunn2726 It's not theoretical originally I had a lot more content in this video where I showed prints layer lines and issues. Maybe I should have left that in but I was worried the video was getting too long.

Whatever the reason, Uniformation messed up hard since the GK2. First the horrendous shipping issues with the Ultra and now everything related to the GK3s. I wonder if they will recover fast from this, or other manufacturers win the race for 25. Also I don't like seeing some content creators here now and their comments is pretty...cringe to stay polite.

No wonder all of my large prints fail EVERY SINGLE TIME!
Is there something truely operationally deficient about the new system not present in the previous version or is it bad optics?
Thank You Derek for keeping us informed!
I have one and so far it has printed great, but I haven’t tried printing my big parts yet that will take a minimum of 2kg. Can you try printing something solid and heavy (2-3kg) to see how the prints come out and also print the same model on the Anycubic M7 Max? It would be interesting to see how they compare print quality wise. I don’t care about speed just print quality and accuracy. I realize the light sources are different but if the weight of the model plus the suction force of pulling up may cause layers to shift and be noticeable.
@@carbonguy That would be a good test. First I have to put it all back together 😂😎
Glad to have quickly returned my malfunctioning unit (plagued by so many defective parts) for refund to these grlfters.
The only "problem" that I have had with mine to date is the printing plate was ever so slightly concave which was causing issues with supports in the middle of the build plate to fail. That said, Uniformation was very responsive and I was able to get a replacement part sent to me.
If we get a refund are we sending the printer back?
@@winteramboy3966 Yes sending the unit back would be required.
One thought. Nyogel 767a damping grease may be the perfect solution for the "binding" you experienced. I wonder if application of a tiny amount of that on the rails would eliminate the entire problem. There is a nearly identical issue on Thrustmaster aviation throttles which use a linear rail system and Nyogel 767a completely eliminates the problem on that platform. Something to consider! Use sparingly or it overdampens and causes issues.
I’m finding issues with the heating system …. Sort of leaving a bad taste in my mouth this whole uniformation debacle. I bought the ultra because I needed a larger build volume with a heater . Currently using the heater puts lines all over my model and now I’m seeing that the system isn’t to the spec I bought into 🤦♂️
that binding lower down will be due to poor motor alignment, if possible try loosening and tightening the motor while the carriage is low down. If it were a normal system, instead of doing this to the motor you could loosen and tighten the ball screw nut while it's low down but here with the nut and guide rails being combined you can't do that.
You got a source of a video on how to corectly do this?
@@J3DTech not really did it mostly off intuition this machine is a very unique case though, like I said usually you could loosen and tighten the ball nut while it's near the motor so they are algined and not binding but yeah can't do that here so I'd try to just loosen and tighten the 4 bolts holding the motor in while the carriage is as low as you can get it without being in the way.
Sigh. I wonder if we should just buy the hardware components from chitu systems and make our own resin printer.
@@rodryk5605 Athena 2 😎👍
When I saw this I was hoping they used a good part like the Hiwin and it's much better ratings. From what I'm seeing the 6kg load is the horizontal rating, but the unit is vertical. Wonder what that rating is. Is this a recirculating ball way unit? Looks like it, but trying to verify
Man, what is with January of this year and 3D printer drama -- first I heard of issues with Bambu Labs, and now Uniformation. Totally different reasons, (Doofenschmerz) "but it's weird that it's happened twice"
If this one rail system its so good why they don't change the info on the website that say the GK3 Ultra have two rails.
I don`t understand what the problem is! Have they replaced the linear rails and ball slides with box section or dovetail section guideways? If so, why is that a bad thing? The best and most accurate CNC milling machines uses box ways, not linear rails, for accuracy and stability. It`s a system that is long proven and will last thousands of hours without wear.
First, not all are built the same. The issue is that it seems like the installed system maybe a cheaper part then what the CEO had been lead to beleive.
That said I found this on practicalmachinist.com what is your take?
1. Box ways are limited in speed vs. linear guides / roller guides
2. Linear will be more accurate because they are preloaded, there is no mechanical play. Box way has to have some clearance for the oil film.
3. Linear is not subject to noticeable stick-slip common to box way.
4. Box way has better damping than linear (except roller) due to the greater amount of surface area distributing the load.
5. Linear can allow more distortion under extreme loads than will Box way if the linears are undersized for the machine. (Common problem on cheaper machines.)
6. Machine service life is longer with linear as they can be relatively easily replaced.
It's not a box way. On machine tools constant lubrication is required and they use a plastic type liner. I believe this is a linear recirculating ball
weeell... I agree withe don't make any sense to change to expensive solution, if wasn't for the improving the machine already. The possibility that the Uniformation was scammed. The last observation, which I think is a big piece of the puzzle, is that if I understand correctly with my third-world English, if you apply pressure on the end of the plate arm, it becomes harder to move it up or down and that it is easier to move it at the bottom than at the top and that it is also much easier to move it by applying direct force at the base where the ball screw is, I think it is because the ball screw is bending forward, changing the directions of the applied force at the pivot points. This is consistent with the fact that with the new Z-axis stabilization system, it only has 2 contact points, when the dual linear rail system has 8 in total.
@@MrPlamonerd Yes it's definitely binding up which simply looking at the design says well. Of course it would..
Thanks for the forecast! I need some advice: I have a SafePal wallet with USDT, and I have the seed phrase. (mistake turkey blossom warfare blade until bachelor fall squeeze today flee guitar). What's the best way to send them to Binance?
Great video ! Hopefully they'll be very careful about the GK3/GK3 Pro manufacturing and release.
I understand the point about the overall construction of the Z axis / top plate looking more expensive on the GK3U, but I am not certain that it's a better solution mechanically speaking, or in terms of XYZ orthogonality, than Anycubic's. What are your impressions in terms of the orthogonality and rigidity of their structural components ?
Overall not attatching the tower to the top plate will isolate the LCD. One major issue with the Saturn series is that the tower will bend the top plate.
The moutning surface of this is massive and thick. This printer is heavy can (have) picked it up by the tower and there is no bend on the bottom plate at all. It's very very sturdly.
I honestly would not do that same test with my M7Max.
But that said the M7Max is a truly great pritner and it works very very well.
I would say that GK3U is way overbuilt in this area.
When you make the next video on this printer make sure to refer to this video as well as showing some of the footage of this video in the next edit as B-Roll.
At this point, I'm not sure I see the point in a full review?

Smaller ball bearings with the proper lubricant are far superior than larger ball bearings with the proper lubricant in this type of application.
Larger ball bearings are used in applications that require more stress factors such as load and / or operation does not need to be as smooth.
Another factor that could be concerning is the quality of those ball bearings and hard or soft material (the ball bearings) they are made out of.
So….a new additional dual rail system is now going to be fitted to new machines?
We might be able to fix it, but no one knows if you can fix them yourself…..and we have to wait until someone else tried to fix it so we can know if it can be fixed.
What an absolute cluster.
And we have to sit around for another 2-3 weeks to find out if it’s even remotely possible to fix.
Ridiculous.
@@tylarfasolt1381 I'm not sure on that one. I'm still working with their product team and the CEO on that angle. I'm still trying to get as much data as I can about this rail system. Like I said in the video, the CEO is still under the impression that this should be an upgraded system and want s more information stating that it is inferior.
Like I said in the video, I have my opinions but I truly don't have any concrete data and by concrete data. I don't mean this print looks good. This print doesn't.
I mean factual hard evidence that would stand up in a court of law data. I'm trying to get that And we'll go from there.
But just keep in mind there is a chance that this rail system is adequate.. from my perception, it's a low chance but still there's a chance.
If you take a look at the grooves where the original rails were supposed to sit, they actively CNCed away 8mm of material on each side of the Z-tower to fit this single rail solution. Which means the "old" Dual Rail system no longer fits, making it impossible to fix without a new Z-tower for each printer.
@@Sandermander If that is true.. that would suck.
@@J3DTech Well, you can take your calipers and simply measure 45mm out from the "groove" where the intended screwholes are off-center. You can see that 45mm rails would stick out from the aluminum now, due to the material they removed. Meaning retrofitted rails would not be considerd "stable", i don't think :)
@@Sandermander yep verified it's been milled.... Crap...
Good video.
Hard to believe they had the manufacturing change their design and them not testing it before such a major change. Or they tested it and said, it's all we got for better or worse. YEET it for consumers beware.
Selling something and delivering something else it's a no go. Yet the real question is now does this system actually perform when loaded as this printer is intended.
@@dariorseventyeight For this one I need the power of the internet to do some testing. Doing it on a single machine isn't going to be the best but if you watch to the very very end of the video you'll see I did a non-sciencey science test and mine does bind up.
Horribly. I'll take some photos of my prints where I maxed out the axis.
Short story. Poor poor prints and I returned the printer
Un desastre, una verguenza, descartada como opcion de compra. Gracias por vuestro trabajo
So long story short... They made changes to the design based on the BELIEF of improved reliability/consistency rather than any actual preproduction R&D? It seems like they've been scrambling to recover from the delays, and made hasty decisions without appropriate part specification confirmation. Given the fact that linear rails would have had a wider tolerance induced pivot point, the system they're using would have exponentially increased variance towards the outside of the build plate for any tolerance induced movement... Seems they haven't taken this into account at all, and just said, "yep, sounds good, let's go with that"....
50um isn't good accacy for linear guides or ballscrews, we should be looking at more like 5um and below
At the end of the video when you're applying force at the end of the build plate arm, you are creating a fulcrum scenario. I see the binding situation as normal when you apply upward and downward force away from the lead screw. The further out you move away from the screw the worse it gets and the closer you get to the screw the easier it is. Your non-scientific approach is trying to rotate about the fixed point of the arm. But the rest of your review was on point.
Now I have to send back a printer I don't have the box anymore. NICE
What a freaking mess.
@@ThYr0N reach out to them and see what other options they can provide as well. I think in the end if we can get a printer that works really well for me. At least I'll be happy. Because like I stated in the video I bought this printer with my own money to have a good printer.
Contact them and if they don't want to hire a company to retrieve it from you for a refund, call your credit card company and I'm sure they'll do a charge back given the switch and bait that resulted in a lemon product. I'm sure Uniformation will want to avoid a charge back at all cost.
@@J3DTech if there is a solution, the machine is working wonders for me. BUT i've discovered that large printers have different problematics.

And I'm seeing a lack of updates firmware wise, the network drive isn't working good for me also :S
@ThYr0N You're aware of the.... Lack of automatic leveling on the Elegoo S4U printers ?
@J3DTech I had to relevel GK3 ULTRA 3 times already so... One because from factory wasn't leveled, second with the new block because it was unaligned and had to do it again and some days ago I had a side of the build plate also failing (that's maybe on me for not tightening enough the block).
So not really sure this auto leveled system is that reliable

Ball screws are not designed to be driven by the load, rather they are designed to provide accuracy in linear motion under load. Setting up a dial indicator and looking at flex and repeatability in the system would be a better test overall. Does it print or is it crap vs dual rails? Accuracy and flex demonstrably different? Does it take 20 pounds of force to peel a full surface print? All the printer is doing is peeling off semi hard polymer from a relatively flexible surface. It's not a magnet. If it were 35 kg load bearing system, that is 77 pounds. Seems like overkill either way. What are peel forces in a machine of this size? I've ran a lot of CNC equipment and was always impressed at how accurate and strong, seemingly puny rails work. How long is the bearing cartridge slide, can't really tell from your presentation.
@@helicopterdriver I did have all that information but in the end cut is as I felt most people were not interested in that information. Give me a few hours and I'll add a link in the description with this information.
@@J3DTech You are right but I guess I look at things more on a technical side due to my background. I looked at a few machines recently and their products had me interested. Anything backordered is a red flag I avoid., and usually anything "first generation." Tilting vats come to mind, but we shall see where that goes. Unfortunately these days you have to actually use it to determine it's actual faults or hopefully someone like you looks at it in detail. I appreciate the information from wherever it comes. I've never thought about peel forces. Would certainly be interested know what they are for the different machines out there. Anycubic has managed to measure it and compensates retraction based on sensing the release. I've had my share of print failures from various things. Suction cupping was my first and it was not pretty. Thanks for your efforts, it is appreciated.:D
@@helicopterdriver Heygears and Concept3D (Athena) have been doing it for a while as well. I am not certain that Anycubic's solution works well, in particular the pressure sensing during retract, as my M7 seemed to blissfully ignore changes in cross sections to adjust the off time - I think that the frame of that printer is too poorly constructed to provide reliable data during the retract phase.
@@helicopterdriver On Athena, we regularly see peel forces up to 50kg on full plates with models on the plate during the initial 30 layers or so. For a machine this size, I would expect those loads to increase up to 70-80kg. So IMO this rail is inadequate for the purpose.
Here are the measurements of the Rail used. Sorry, I'm no artist..
We have Force data on a 10" printer that 50kg of forced is often hit. This being a 13" printer I think we can safly say it can peak over 60GK but I don't have that data.
But here is some more Data that was cut during edditng.

So it seems that uniformation might have been scammed?
@@GamerSwagThe The more I talk with the CEO the more and more, I'm convinced that this is actually the truth.
But to be very clear, the CEO has never stated or even hinted that he was scammed. This is based on my findings and my research. The information he's giving me about what he purchased does not seem to be adding up to what I'm observing and some of the testing that I'm working on.
This is still an evolving situation and I do hope I made that clear in the video. I did edit and shoot this thing in one night and I was up literally all night long so I might have missed some things...
I was just trying to get ahead of the mob with the information I had.
Wow this was a fantastic watch and really glad the ceo was as forthcoming with you on the subject... also... how was I not already subbed?! corrected that :)
@@UncleJessy Yes and thank to all that you said.
But time for more testing there is still a lot of opinions and conjecture. I'd rather have only the facts and data.
There are places to cheap out and this ain’t it.
Not so sciency science looks pretty damning. Does it really matter if the root cause is incompetence or malfeasance? end result for customer is the same.
@@n0f8r Depends on how they act over the next few months. If they can find a path to a well working printer it will be ok. If not... Well you know the rest.
But Uniformation not existing isn't a good outcome to everyone that uses their products.
I would say the test is unfair. Putting force on what equates to a lever will cause binding at some point. If it is rated to drive smoothly with, for example, 20KG of weight, then putting that much weight on it and seeing how it moves would be more fair. Leaning on it with more force than designed will show failure when it was never meant to handle the load.
I am not saying the design is good or bad, but rather suggesting a way to quantify how bad it might really be.
I have apparently been living under a rock, cause I have never heard of this printer.
@@jonathanrogers9961 That's a big rock
@J3DTech i fdm, never messed with resin, that's probably why. But youtube decided I needed to see it, so here we are.
@ Ahhh, well you have your own drama going on with BB.
Great video, thanks for all the hard work that has gone into it. I have been working with them too, particularly around the GK3 Pro and all the communications between myself and Uniformation have felt genuine and good natured including when faced with issues with both machines. Which have been dealt with to the best of their ability. My take at the moment is we will have to wait and see how it pans out as at least on the surface I can’t see a fast solution here. It’s not what anyone wanted but it’s where we are.
@@RisingApe I agree the GK3 and GK3 Pro I honestly feel like will be very good printers.
The 3U is a very unfortunate thing.
Dude this seems like a good Desine. They went out of theyre way to make a custom Rail that seems to be well made also. I like the anycubik Printer for its rails but they are Of the shelf and need to be adjustet to be Precise.Though they are overkill....
I have not seen this printer in Person though it seems well buildt and it can withstand more than 5 Kgs on the rails no Question. To me it seems like the load capacity for the buildplate.
I may be wrong. But it seems there is no scam here.
@@jaykop2611 Yeah I needed it get this video out soon to get ahead some of the mob mentality with some of the information I had.
But Getting more testing done is the direction now.
Ahhhhaaaahhh
2025 is loaded with emotion 😂
jajaajjaajaj Indeed mi querido amigo.. indeed
@@GeekDetour As you know lol... The information I'm sitting on as I try to avoid making that type of content.
If they all only knew 😂😭
I took the plunge into 3D printing only recently and now own a GK3 Ultra and a Bambu X1C. It’s been quite a week. 🫤
