Another excellent review. We can always trust you to do critical but fair reviews. The other resin printer reviewers you have mentioned unfortunately can't be trusted as they can't seem to offer an unbiased opinion. I follow them too for context. I guess what I'm saying is you do a great job, don't change your approach.
Thanks mate i really appreciate your support. though in fairness, I have watched all of their videos on this just now and I stand side-to-side with every single one of them. Though I haven't seen @GroundEffected's video yet, but his is more for just fun anyway, which he is clear about...
This is crazy, the more I read about these new printers, the more I like my Elegoo Saturn 3 ultra…
Especially at a black Friday price
@@azyrael96 I scooped that up so fast when I saw those prices 👁🫦👁. It's the hottest piece of machinery I own now. Hotter than my 🔫 collection.
Bought saturn 3 ultra half a year ago and its been a blast using it i've used up about 6 liters of resin to this day with maybe 3 or 4 failures wchich were errors on my part
can i ask why?
(i've got the gk2 and quite like it but i'm sure i'll be getting something else, at some point, and elegoo's pricing is tempting.)
I love you honest reviews. It is why I took the leap and ordered a reflex rs
Thanks mate. Would love to know how you get on with it
It was really nice talking to you! I think you are one of the most down to earth person and i really hope, that you can achive what you told me and the other guys. Thank you for helping me out on my decision for my future resinprinter.Cant wait for youre Saturn4 ultra 16k review... I was not expecting you when i was looking for my train but it just adds more sympathy to you. Thank you and i hope you got your flight in time!
Thanks Leon, you too. I’ll assume you found your train.
I didn’t fly til the next day. But I was so tired at the end of the show.
I own a GKtwo and have been incredibly happy with it. I haven't had to level it a at all in the past 1½ years, and it's just incredibly consistent.
If I have fail, it's 99% guaranteed to be user error.
When I look at the new printers, I don't see anything wrong with them.. But I don't see anything new and big enough here to even consider upgrading. If the pump was completely clean, pressurized AND could bubble the resin to keep it mixed in the bottle, and if it had features related to pressure sensing, then PERHAPS I'd consider it.
But considering how I use my printer, I just don't see any value gain with any of the 3 new printers. It's a shame really, because I expected a lot more from Uniformation. Especially because they don't spit out a new printer several time a year, like some other brands do.
I think that’s the key point… it’s not bed. But they set a high bar for themselves with the 2. Failed tk realise why it was better. And failed tk hit that level they set in the gk3
I'm so glad I didn't order the GK3. Thanks for the great review. Much respect for your honest and unbiased review.
Great review as always! Thank you for covering the details and information we actually care about, and being honest about the pros and cons. Too many reviewers out there these days whose “reviews” just sound like a marketing overview.
I appreciate that! But all the guys who reviewed this so far have been equally as honest. I have watched all of their reviews and stand by them
Just a few hours too late to watch this live. Brilliant unbiased review yet again Ross. Ive got to say I'm shocked by the lack of progress made over the GKTWO, which caused me a lot of stress trying to choose between that & the Reflex RS.. I'm so glad i made the choice i did though, especially since the GKTWO is no longer being made. I had my worries id bought wrongly when these printers were launched but i can see I made the right choice for myself. Great review as always & dont let the doubters drag you down 💪👍
Thanks for the review Ross. I almost kicked my self when I got my second GKtwo a few weeks ago and then the GKthree was announced but seems I made the right choice. Although I'll probably get one in a year or so.
I feel like if rather buy another GKtwo instead of a GKthree
Superb, comprehensive review. Great job!
Thank you for the review. :) Seems like it isn't a bad printer, but I'm definitely happier with my GKTwo over these. Maybe I'll be back for the GkFour :D Maybe with the lead screw and the proper release liner. :D
The fact that they told you these were production machines initially, pretty much sets the tone for the rest of the video. I'm not in the market for a new printer, but if I was, this would be disqualifying for me for their entire brand having not experienced the greatness of the GKTwo. Either they misspoke or they really think this level of production is customer ready (kapton tape?!). Hope it's the former and the actual production machine will be much more finished.
They have acknowledged a lot of this this week, and I expect we will see some changes in the final units. I can't say what though. Pretty sure the power button will be moved.
Great review. Thanks appreciate your time and effort.
Thanks for watching!
In addition to everything you've said about the usefulness of a pressure sensor and its unsuitability for so-called "auto" leveling, from 23:59 onwards (which I agree with 100%) there's another decisive element that you didn't tell here, but that you've detailed in your previous review of the Anycubic M7 Max (at the 8min35s mark in that video): the fact that the pressure sensor can also be used for "dynamic lift height" i.e. detecting whether the film has actually detached or not from the printed part, so that the printer stops lifting and starts retracting immediately regardless of the TSMC settings made by the user in the slicer, saving considerable time in the end. A smoking gun feature in my opinion, and a great way to speed up big format printers despite the larger film area to pull and resin volume to push against (which is Uniformation's excuse for the slow print speed of the GK3 Ultra). QED.
Yeah I had that in the review initially but cut it down for time. There are many applications.
Great honest review. Thank you.
So, they drastically dropped the prices for both of these just got a new email showing it! It's junk and they know it!
Hi Ross, wanted to say hi when i saw you on formnext, but you were busy talking to some other visitors. Interesting to see a youtuber in person :-)
Aww I wish you’d come over and said hi!
I can't wait to see you paint that 25th anniversary mini!
Thanks for the video, a very fair breakdown and comes at the best possible time. Very useful for people like me who were waiting for a sale to buy a GK2, and are now presented with the GK3. Sounds like both of these machines have different mechanical shortcomings for no reason at all. I'd rather have the screw of the pro, but the light of the regular - and it sounds like you can't have the old reliable film on the pro or the light will mess it up. Smaller screen as well ffs. In both instances it looks like I missed my chance to get an amazing GK2, replaced by a sub-par sequel. Forgetting all the new stuff I don't care about, they managed to go from being top dog, to "printer with a heater" in one iteration. that's crazy.
Doesn't help that black friday, biggest pre christmas sale and the uk warehouse was out of stock before the sale even began. Meanwhile, uk resellers are selling the GK2 for the same price it was near the start of the year - it's fuckin cheaper to order a GK3. I'm laughing but what a shame
Thanks again Ross for a great review. A company that wants feed back but doesn't accept highly valued advise tells a lot about how hard they are listening. Looks like to many issues to be fixed before going to market is a sure way to lose customers. What put me off - The poor plastic look, the smaller build footprint, the tilt screen with finger print marks and all the other things they need to catch up on.
This video makes me even more happy that I canceled my GKThree preorder and got a HG Reflex instead. I still have my old GKTwo for larger prints, but the Reflex has been my go to ever since.
How are you finding it? What do you print?
I got a GK2 about a week before the 3 was announced and this makes me glad I got it when I did. I'll just pick up some spare parts and hope a worthy GK4 comes round before my 2 goes.
Yeah. Gk2 is solid.
I very much appreciate this video and taking my first leap into resin printing, I think that I'll wait on the GK series overall. For pricing and features that others have (especially now for the holidays) I think the Anycubic M7 is going to be the one I go with after looking at several other brands.
"I'd have taken an extra half inch" 😂😂😂
First person to spot it!!!! or at least to comment!
in my original draft, it was much more obvious with a follow up "would like an extra half inch"? but i decided to make it more subtle as a treat for those of us properly listening
glad you smiled
@FauxHammer hey man if there's an innuendo, I'm gonna be right up in there!
Big love my dude keep up the good work
I have 5 GKTwo printers in my little print garden... And they are fantastic. I was concerned when Uniformation said they will continue to provide part support for the next 1-2 years. But maybe longer... ( I don't exactly know what that means). I have never had an LCD screen fail on me. My first 1 year old UI screen finally had an issue and they are shipping me a new one. The build plate size probably wont be a problem for me. (I do production runs) But the heater is the whole deal for me. So I'm pretty committed to the brand.
You're review has left me with these conclusions: I'll buy the GK3 when it comes to it. I need the power button on the front, so I will make arrangements for this or just install a new switch in the front which will be easier to do with a plastic body vs the old aluminum one. I also like that they slide around. I often need to move them for various reasons and prefer to slide them. I like the flippy front display. I often find myself bending over staring at the UI for whatever reason and if it flipped up, I would stand up straight. (Its funny I was just thinking about this yesterday) I like the higher resolution screens. I'm printing very tiny, very fine parts and can use this feature. I've never had anything wear out on my other than the FEP and screen protector. (I've had all the "things" happen to me too. We all have.) That being said, I will only use the clear FEP. I don't care if it tires faster. I'm printing so much, the FEP will go bad from the usual wear and tear before its "burned up" by the light. I do wish they had the pressure sensor. I leave prints sitting overnight and sometimes I don't notice the small ones in the morning and in my stuper... start something that I should yet.
Ultimately, the biggest thing for me is their customer service support over on FB. Its hands down, the best I've ever experienced. Knowing that I can rely on it is extremely important to me and my small business. While I've heard some complaints about folks not getting answers to their emails (You really should go through the FaceBook Group first) I've never had anything but good experiences. So, I think I will be switching to the GK3 when the time comes.... Unless.......... my GKtwo's last so long that I find myself watching your GK4 review ; )
Great Job Ross!
Brilliant! This is one of the best comments I've ever read, You watched my video, my sour opinions and ignored the irrelevant stuff to you and decided on it based on what matters most to you. and yes, I agree they have been great at taking care of people. I'm sure they will do the same here.
AS for your power button, you'll be happy to know that we showed them the issue last week at formnext, where we put 3 printers next to each other to simulate a print farm, and showed that we could not turn them off as we could not reach.
So they said they will change it!
@@FauxHammer That is fantastic! Thank you for doing that. I'll be making a purchase when I need a 6th printer or one of these GKtwo's dies or they stop supporting it.
Great review Ross I was sat in the fence on this one and Hygears. I think if HG start introducing 3rd party resin profiles they will fly off the shelves. I think for this one I was expecting too much
So was I.... (sadface)
@@littletedsplayschool2525 One thing I would have liked with the Reflex though was a backdoor to the resin cartridge area in order to make cleanups easier.
Nice. This video will probably be the one that determines my next printer.
that tilting screen is dope. im an fdm guy so i hope they dont go full elegoo and just stay in their lane
For my first resin printer, I was really looking forward to buying a GKtwo until I saw they were on a clearance sale and saw your initial video announcing the GK3s. I figured the three's would have a lot more features and match or exceed everything else on the market but, they seem to have fallen short. And to add they are still having issues getting their Ultras out to everyone that preordered which doesn't look great for those that preorder the three and the pro. I honestly don't know if I'll purchase a uniformation product with the GKtwo's end of life, the lack luster three series and the production/shipping issues they still have. Thanks for the honest intial review.
I hope they can recover quickly.
It's like the super intelligent management fired the capable team that made the GKtwo and now they are left in shambles with only the marketing department working.
Same people.
Well, I have done it with my GK Two. It punctured FEP and screen and leaked all over screen and needed to replace it 🤣 Don't know man... GKTwo was really "without compromize". Ok, price was high, but it was worth it. This just doesn't seem like it... Also, good on you mate for taking extra half inch... You go man🤗 As you said it, we were all expecting GKTwo for new generation. They are amazing printers, but so little seperate GKThree from other printers on the market. And, as other companies, they released 2 printers that are so similar that they defeat purpose of eachother and for those of us who already have GKTwo, there really isn't any need to buy new printer to "upgrade"...
Thanks mate. Maybe that no need to upgrade isn’t such a bad thing. Have we plateaued? Not sure. Next year will be interesting.
Could you also do a review for engineering applications. Like cubes with different sizes, thin and thick walls, different holes, two parts that slide into each other. So it's possible to see the printer error and tolerance. Would be very nice.
For me I hoped the uniformations line of Printers would be more affordable, but compatible to formlabs in accuracy.
I would, but I'm concerned that would completely change the format of my channel.
@@FauxHammer I greatly value your unbiased reviews, Faux. However, as resin printer technology advances and differences become increasingly subtle to the eye, I believe it's worth it to explore more scientific methods of evaluating 'print quality' while keeping it interesting for the average viewer.
Visual inspection remains crucial, but it's not sufficient to fully assess the nuances of modern resin printers. Even more so for upcoming printers in the coming years. For instance, the choice between 385nm and 405nm light sources, often overlooked due to imperceptible visual differences, can significantly impact print accuracy and resin choices. Perhaps incorporating some quantitative measurements, such as dimensional precision, could provide valuable insights without sacrificing your review style.
@@Daan87423 yeah, i suppose, as you put it that way. And yes i believe this needs to come in at some point. but it needs to be drip fed.
Right now, people are just learning that there is a difference between 385 and 405, when i next review these I intend to figure out a way to show that differenc.
The key is, well, this is TH-cam, i need to show it "visually", but i also need to explain it in a simple way to about the haters and their "Yeah-but" atitudes.
it;s good advice, and I'm strongly considering it.
Beautiful review as always
Thank you 🤗
I never owned the GK2 and was thinking about getting one that the price dropped but it's kind of dated now and, IMO for best value for the money in mid sized is Anycubic M5 and M7 series and the Elegoo Saturn 3 ultra. I own several of these printers and they are great. My m7 max will arrive soon. Can't wait. I really wanted to add the uniformation to my collection but they fell short, for reasons stated in my first comment.
If uniformation doesn't see the value in pressure sensing then that says a lot about the knowledge of their engineers or development team. That will absolutely be a deal breaker for me as I have started a print with a print on the plate and destroyed my screen. That was on my elegoo saturn 3 ultra. Also not only starting a print with a print on the plate but there is also the possibility of floating debris in the tank that are not noticed. This is one of the reasons I really like my Anycubics. I really wanted to buy the uniformation but without that feature it's NO for me. LCD are too expensive to replace because I'm sure I will make the mistake of starting a print with a print already on plate or debris in the resin tank. I hope they add this but until then...
It looks like uniformation is taking a step backwards with the screen size as well.
Uniformation really went from Underdog to being part of a mediocre market. No pressure sensor is a feature that should be included in any printer, especially at that price class and with their (now old) brand image behind them. I wonder though, how the pro will turn out with their new release film and what audience it is supposed to serve.
And now they're determined to trash that well earned reputation. The GK Three Ultras still haven't shipped and here they are releasing two more printers while existing customers are still waiting.
I have tried to cancel my early bird Ultra since the preview you did came out. This unit was due to be shipped in September but still hasn't arrived. I feel like I've been shafted to fund the production of these new units. I was initially told that they would cancel it. Then I received another email saying that actually, they'd misread the order number and my order was shipped on the 22nd (convenient). I've now requested tracking information or proof of shipping because they've provided nothing and haven't heard anything back. Even if it does arrive, I've seen multiple people reporting that their unit arrived damaged.
Can't say I've been very impressed with Uniformation as a company at all thus far.
Same here. Ordered on 24th July - still nothing. Any week they say it will be shipped now. I’m pissed and disappointed of what I heard of Uniformation
@mietz I've just complained and requested a refund. All of a sudden I have tracking information and my order is being dispatched...
@ I did the same now and requested a refund. Let’s see what happens :)
Glad to see the wifi change. I broke the wifi on my GKTwo because the USB got damaged in a move.
Damn! but still definately worth unscrewing this time before a move.
@@FauxHammer For sure but this is a lot less likely to get damaged
@@JohnVanderbeck yeah, fair
I love my GK2 and was hoping for a bit better from Uniformation. The GK3 is more of a GK2 Pro imo though the smaller print plate is a no go for me.
So far on FormNext they told me the PRO will have 385 Wavelength instead of a 405 . 385 makes it much more easy to print clear materials and is probably capable to print the most DLP Materials as DLP Industrial Printers print on 385. I like that feature.
Hey Ross .. another great review ..... i'm no expert but the gk3 models has taken a stall from doing the gktwo .... but, if i had to chose a gk3/ultra/pro or a heygears rs ... RS would be on my bench for the price.it's bigger and better
I’m glad this was helpful.
The gk3 has a SMALLER build volume then the gk2 😂😂 great job
Yep…
Well thats a bit of an F. I was expecting more of the gold standard. Im now split between the GK2, M7 Max or something else, and i have no idea what to get while black friday is still on 😢😅
I love how they refuse to tell us when these would actually ship
I never noticed that
Mh what i allways loved at my GK2 was the slightly bigger buildplate compared to other 10 inch printers... :/
Well and btw i started prints with whole tanks still on the build plate 🤣🤣
Haha. Yep. I’ve done that too…
Sounds like a wait and see if UniFormation improves the issues.
That’s what I’m doing.
Thank you for another great in-depth review! I know this isnt directly related to the GK 3 or pro, but after this video and seeing the release on these printers im heavily concidering the ultra. I know you say it has a weaker light source that "smoothes" prints, but how much does that actually effect the details on smaller models? Would fur, spikes or spears be rounded on miniatures? would hair be smoothed out? how minimal or extreme? your input would be greatly appreciated. I'll make sure to use your link if I end up purchasing it
we need a gk3 mini now :D
Was about to sleep, but lets go!
Hey Ross, the shorter wavelength is providing more energy to the resin. In theory, this might make the resin cure faster. Have you found any difference in exposure time between the two printers?
Edit: now that i think about it that could be something that is impacting the results you were showing between the 2 peinters in the video
Yeah, based on these exposure test. I would need to lower the exposure on the ultra
i pre orderd the GK3 ultra cause of your video month ago and still wait for them to delivery since august , will they ever deliver ?
It seems they are having issues. Are you in the Facebook group. The latest updates are in there
Can you opt not to use the resin pump and just do conventional fill? If not, could you maybe feed that back to Uniformation as a needed feature? I HATE resin pumps... if I can just not use it, this will be an immediate purchase?
Yeah, you can not use it. That's what I did, I just turned it off
Really shocked and disappointed at the GK3, i love my GK2s and was so looking forward to this printer, but i think I'll give them a miss and look at other companies for my next printer, 😢
Well. On the plus side. There’s no drive to get a new printer and the GK2 is still solid
damn live at 3am east time rip hahaha, gonna have to watch this one when I wake up! good luck!
weird to think that the wavelength diffrence is big enough to help reduce bloom. guess I need to look up how big the waves are.
Nice “click-bait” thumbnail.
Thanks... I could go either way with this statement...
😥 Didd thay squrew up...ore didd yoo?
Iz thatt wot yoor baitin me teeny brane wit??? I feal lyke a wazzuk noow! 😢
Is it good sh*t or bad sh*t. We are now compelled to smell to know.
@@MrShaneSunshineyes…
@@ThoughtsFew is it either… is it neither?
Not long to find out…
so which one to get :-) ? I'm between the Anycubic M7, Elegoo Saturn 4 Ultra and the GK3. I don't care too much about print speed since I do most of my prints over night. I rather am looking for sharp and detailed prints. The heated vat on the GK3 is a nice addition.
If you want the heated vat. Probably the gk3 is the best choice for you.
Considering the GK3 Ultra, those won't release before 2026 so they'll probably be very outdated by the time they release.
I hope they can pull this back
I don’t usually comment on things but I am shocked at this review. For a company known for so many practical upgrades that set their printers apart it seems like such a misstep when they had all the feedback to nail this model and control the market for years. That on top of the timing of releasing this printer for you to review so unfinished and still in development seemed like a huge mistake. Especially knowing how honest you are with your content. Not only does it seem like there is hardly any innovation but it rather seems like a downgrade from the GK2 in some ways. I was confident that I was going to be purchasing this printer as it would have all the features I need instead of the majority of the market having only 3/4 of the features but now I think I will just end up pulling the trigger on a Black Friday deal from another company. As always fantastic content and thank you for being so incredibly genuine in your reviews.
I think they fell in love with the tech and they have reason for including these components but I think those are in contrast to market wants.
I was fully prepared to order this printer, but have decided to avoid it based on your detailed review.
thx
Hope you enjoyed it!
@@FauxHammer
Yes, very informative and valuable knowledge!
Thx!
Great review as ever! What a damn shame. I was hoping for another levelling up by Uniformation but nope. It's like whoever they had that developed the GK2 has left and now they're left floundering. Some really bizarre choices (small screen, pump, rotating display, soft and scratchy output of the pro), announced / released before they're thoroughly tested (it felt like the GK2 came out READY) and no pressure sensing... game over. I can't imagine why anyone would go for one of these when the Saturn 4 Ultra is so much cheaper, faster, simpler to use or the Reflex RS that isn't that much more expensive really. Again, what a damn shame.
Elagoo have upgraded their screen to 16K for S4U, it also comes with an integrated vat heater and a bettter handle to hold the build plate. The refill system on GK3U has failed in many cases, resin spilled all over and inside the machine, which damaged the printer beyond repair.
@alfredanil i heard this but can find anywhere. Is there a preorder for 16k version, upgrade, release date or something?
@@88RunnerBlade it was launched at formnext. Not many details have emerged yet. It's got the same resolution as 16k gk3. I guess both are the same build area too. Two brands using same screen can reduce the replacment screen cost in long run.
i still don;t have a date. surely a black Friday launch? It is limited though with the vat only heating to 25C :(
I'm excited to try it..
I was pretty hopeful for this being my first resin printer but this feels like a poor compromises to make price point. The search continues.
Great Video, Ross! Like I said to you in Formnext, I'm a SU4 owner and I very disappointed...I need a new printer that shouldn't give me so many troubles, GK2 would be my choice and now? Go to GK3 or keep my mind on GK2?
Depends how much the build plate size means to you to be honest. and you should have more longevity of GK3, it is also at preorder price right now. and you will also need to wait for it longer
@@FauxHammerthanks I’m similar situation I had to return my little mars 5U as it kept freezing. Was assuming I’d get the pro but now it looks like the GK3
I am even more confused on whether i go with a GK2 or GK3 now..
I only have experience with my Anycubic Ultra but the print plate is too small for the figures i want to print, so i need an upgrade.
I would like the GK2 build plate size, but i really do like some of the improvements to the design of the GK3, especially the topper being easy to take off and holding thing for the build plate! But i don't know if i should just go with the slightly cheaper GK2 and wait a few years for more improvements..
I live in an apartment, and i print in the living room, right now we have a plant growing tent with ventilation that we can pop out the window for when we print, but it is not big enough for the way the GK2 opens the topper.. So we would either have to get completely rid of that tent and connect the ventilation conversion directly to the machine, or get the GK3 where we can still use the tent contraption 🤔
I think there will be some changes to the retail GK3 models which improve it a bit. but the screen size and resolution will remain the same.
It's still a solid printer as I said. But I miss the pressure sensing features because I'm a regular dumbass and the screen size bother's me. @BattleBrotherSam showed this better than me when comparing the GK3 plate to the GK2 with minis on the plate, and you can fit so many more on the Two!
I think, if you already have models. download chitubox and create a custom printer with these dimensions, and see if it bothers you enough?
Well they are already starting to take orders so I have a feeling that no improvements have been made since this video, so, either they change things before I order or I guess I'll have to see if I can get the MK2 and spare parts asap before this one goes bye bye!
Oof.. only 6.6 GB internal memory on a "16k" printer. I already had some files reaching 1.5GB + on my GkTwo, this will be like 4x the amount of pixels. Gonna be "fun". Should have at least 16 or 32 gb or even better make it extendable with an SD card or something.
Cheers for the preveiw, do you know of the spare parts for the 3 are compatible with the 2, i am thinking of getting tge gtk2 but dnt kno whether it will have replacement parts like the screen in future
As usually great review but real reason why I'm writing this comment is to let you know I'm a Prusa user.
hehehe - so am I now!
Great video! Im am now undecided if it's better to buy a Saturn 4 ultra, a photon mono m7 pro (or not pro based on your videos)or Gk2 for a lower price than the Gk3. I'm coming from an Elegoo mars 2 pro and I loved it but it's time to upgrade and I want to buy myself a birthday gift.
I really like the heated vat since I'd be printing in the garage and would need a separate solution for temperatures but one thing I love about new tech are the sensors to detect failed prints since that is a major pain with my printer. I mainly print figures and speed is not something I consider since I'd be printing during the night and would care after coming back from work the next evening, I just want something reliable that makes life a bit easier. 😅
Elegoo showed off a 16k Saturn 4 pro and it’s coming out soon apparently so I wouldn’t go for a Saturn 4 ultra just yet
@Laprak098 woah! Thanks for the info!
@@randomzet sorry I didn’t see the rest your comment I’d go for gk two all day. One of the best heaters. The price is very decent as they’re getting rid of stock and it’s going to have support for next 2-3 years. I was thinking about the 3 or 3 pro and now i know to stick with my gk two
So far the GkTwo is still clearly the best heated printer that I've used, even with other brands own heating options. The Saturn 4 Ultra 16k is coming with a heated vat, but it only heats to 25C, When most resins want 27-29C
Thanks for the valuable infos, I think I'll get the GKtwo now since it's already low on stock, less than 500€ are just too good for the features! And it's a big step forward from my current printer for sure
As a GKTwo owner, I found the firmware to be disappointingly subpar, with placeholder menus that serve no function at all. Perhaps I’ve been spoiled by Bambu Lab’s exceptional software engineering. While I’m pleased with the print quality, this experience has certainly made me more cautious about considering UniFormation products in the future.
How can someone get this printer if he is not rich?
Yeah it’s not a cheap one
while I agree that you would need much much smaller pixels, IM0 like 2um (could be impossible with msla) to get perfectly smooth prints with 0AA, having smaller pixels means you can use the same eg lychee smooth surface 2-4px HD on AA settings and get smoother and sharper results, a 2-4px blur with 50um pixels causes a lot more damage to details than. But yeah the slicing time is a real issue, as I've shown you I've got 3daa to work on consumer prints, it would be much better to start using that tech on consumer printers with current LCDs rather than to go to even higher resolutions where it will get even harder to slice, I've heard of some 32-64k LCDs in the works xp
If Uniformation adds non-slip feet be very careful about what material your supplier uses. Some rubber feat interacts with table finishs and can damage the table. Avoid a law suit.
I’ve not seen this in other machines
Seems like a kickstarter printer rather than a premium high end printer
Yeah. In fairness these are prototypes
Yeah, I've done it too.
lol.
09:26 Worth noting, Apex-Maker, who initially shipped the X1 with these new TCF films, has since backtracked and only supports ACF now, saying that in the end it's better. Who to believe? I know what you might say wrt your personal experience with them, but ACF vs TCF is a broader issue than one brand.
I’ll believe anyone over AlexMaker at this point. They are one step shy of being scammers with all the issues people have had and the awful communication.
Uniformation sent the GK3 & GK3 Pro for you to review with feces stuck to their bed? Was it natural or 3d printed? I have so many questions.
Don’t worry. I have answers!!
Soo... We should just get another GK2?
Don't forget that people can upgrade their GK2 to essentially a gk3 .
How so?
I have a Saturn 3 that's been causing a lot of problems qnd am looking to upgrade, byt after watching this I'm debating of I should get the gk2 if it's not any that difficult from the gk3. But am also open to other suggestions
The GK3 is sharper but not as large as Saturn or GK2 for print volume.
One thing I would like to know, see in the full review, is how is Uniformation long term with their updates? How many of these things can be "fixed" with a software upgrade or are they all hardware limited. For example, my X1C has gotten tons of updates and upgrade options in the time I have owned it. With Uniformation being similar to Bambu in that they let you modify and upgrade their stuff, can this printer get better over time, or is waiting for the next generation recommended.
I think they will change some hardware now.. some…
But I haven’t seen a great deal of experience in the software side.
@FauxHammer thanks for the reply
10:37 fairly wobbly reflection, should be flat!
Will you make cure depth comparison on both printers (405 vs 385nm) on same resins?
no. its something i didn't get explained to me until it was too late. and i have no transparent resin to test it anyway. it;s one of the reasons why this is an "initial" review. There are other reasons.
I need to work out a way to "SHOW" the difference, without it being argued "that's just different curing times" or thicker Supports.
Lets talk after this goes live, because you seem like you are one of the people that understands the difference and there are things I can't fully discuss until after it's live, in case I leak anything.
@@FauxHammer Luckily it's not rocket science. Lower wavelengths are able to 'penetrate' the resin less, so the curing occurs more on the surface. All things equal, this usually results in better surface details because the lower penetration avoids overcuring unintended resin. Lower wavelengths also carry more energy, resulting in less curing/exposure time (also depends on the absorption spectrum of the resin). I'd be interested in what Heygears has to say about this, given that they choose a 405nm source for the Reflex RS vs. 385nm for the Reflex. Resin choice is probably the biggest influence.
@@Daan87423 Sorry yeah, i get this. what I'm struggling with is working out a way to "show" the difference.
How can I fairly show a Transparent test's dimensions on one printer at 405, then show the equivalent printer with 385 and show the sharpness difference.
For reasons you will see in the video. yeah, you do need to reduce exposure time on 385 to make it equal terms of XY dimension. But how will that "look" any different to a transparent print on 2 printers where 1 has a stronger lightsource...
I've heard for a long time that 385 is better for transparents.... We've all heard it. But I'm yet to see a single example that clearly proves the claim... And even if i do see it. will it be to a degree which is actually noticeable to most users?
Is 385 the right choice for hobbyists?
If i get a 385 print and a 405 print and both are dialled in perfectly.... for their UV strength based on the wavelength they output... Will we actually see a measureable difference. and at what level? in microns?
@@FauxHammer Yes it will be measurable, but probably unlikely to be visible to the naked eye. For miniatures this makes no sense to even discuss about, it will not matter. For functional parts that are utilizing structures near the resolution of the printer, this will make a difference. Referring to the XP2 validation matrix you showed in the Reflex vs. Reflex RS video (11:20), you can see that the holes on the RS are filled up near the bottom, whereas the Reflex still shows them. Heygears optimizes their exposure settings (that's their selling point), so yeah, there's your difference.
It would be interesting to see if you can duplicate these results on the GK3/GK3 Pro, also since you can dial the exposure settings yourself. We are talking about sub 100 micrometer differences, no eye or camera will see the differences. Does it matter then for most resin users? Definitely not. But just to show that the difference is measurable, can I suggest you to get your hands on a digital handheld microscope?
I haven't tried transparant printing yet to see the difference, but the fact that the Reflex RS doesn't even support their transparant resin is telling me a lot. I expect that it will result in less clarity.
The 385nm wavelength should help reduce z-blooming
Cheap plastic kinda does turn me off from what the GK2 was made of! Bring back the Aluminum! The MK2 base was better looking! Yep, need the draft strips as well! Darn, wanted the MK2 but decided to wait for the new version and Uniformation does this! Might have to pass on this one then!
One of the things that confuses me is why on earth are these new printers going down in the Z height, as someone you prints primarily 1/6 scale, anything below 300mm Z height is a no go for me, as my first printer was a Saturn with z height below 300mm and can't tell you how many times a part would not fit...I just don't get it.
yeah feels like they dropped the ball. i will get myself some printer in the 350€ range and a heating belt which i can tie around the VAT.
@FauxHammer So if I wanted a bigger sized printer with the best quality prints, would you say the M7 max with the new light source, the ultra or something else it the best pick?
No, the M7 max is only the best pick if you want a big printer. It's my fave printer of the year because it had the fewest stupid , not the best for everyone. It is the best for it;s use category of bigger things.
This is still ok, the GKTwo is still ok. This has all the feature sof the GK3, and more, there are just drawbacks too and itp;s not as modern tech heavy as the competition.
@@FauxHammer You say it’s the best for it’s use case of printing big things. Can it also print smaller things like figures with fine detail too? If someone could only get one print and wanted it to be able to print larger objects but also smaller one too, do you think the M7 Max would be able to do both or would one of the other larger printers be better? Thank you for your information and time too.
Why, oh, why doesn’t UniFormation (or the other mayor brands), bring the top TH-camrs like Fauxhammer and J3Tech and Dennys Wang into their new product focus groups (which they obviously don’t actually have), signing an NDA, so they these companies can avoid or reduce the probability of making new 3D printers with so many basic problems and/or poor design choices year after year???
I’ve offered. I’ve even told them what the response would be to certain elements during development when I’ve heard about them.
I even told them not to release the 12k upgrade for the GKTWO
And here we are…
I have an elegoo mars 2 (yes, 2) and have been considering upgrading for a while. Is it worth buying the GK3, or is the GK2 still a better alternative? In terms of the drawbacks you talked about, I'd only be using one type of resin, don't really mind the smaller build volume and won't want to record my prints or really need the light. Any advice would be great!
I was looking at getting a GKTwo with the sale, but now i dont know if i should just go for the GK3 or GK3 pro? Or if I should go with a different brand. This review made me even more confused.
Exactly as I expected it would…
They’ve made it confusing…
They are all good. New ones are sharper but smaller volume
You only need the pro if you plan to print transparent materials.
@FauxHammer Thank you, for the advice here and for the video. First resin printer and I have found your channel informative. You also called it on the leadscrew for the regular, I would just go for the reg but I wish it had a ballscrew. However does that lead screw vs ball screw really make a big difference here? Sometimes with these systems the material properties throw out any benefit of precision motion systems. I'm intending to print primarily engineering resins & parts, would that have any effect on choosing between the pro and reg? I am a Warhammer 40k fan though so I'll end up enjoying myself anyways.
EDIT: On a side note, it's even more confusing with the price. Buying the bundle, the price between the GKTwo, GK3 and GK3 Pro is almost negligible.
It seems like a round of new features that ultimately don't really improve on the user experience. I'm pretty disappointed, based on the GKTwo, I thought they were really focused on UX
Physically in teh design, the UX is solid and the inclusion of a drip tray and flip up screen in the mechanics supports that.
But in the software, they are lagging behind.
About the build size and screen size … the screen is from 10.3 to 9.6 inches. But if you compare the size of the buildplate according to the uniformation website both printers has a 9.5 inch build plate.
So I’m questioning, doesn’t the gk2 just waste some screen there or do I overlook something
Well I show the difference if a 10” screen from the Saturn 4 compared to this and you can see it’s smaller.
And @BattkeBrither Sam did. Better completion of GK2 to GK3 plates in Chitubox
You can text this yourself by making a custom printer with these dimensions.
genuine feedback for you to consider - i hate the repeated video, it feels like cheaping out, almost AI-like.
Repeated video? eh?
Oops, that wasn’t to plan, was it?
In what way?
I thought this was going to be a no-brainer, but after seeing this review, I am no further a head in my search for my first resin printer. I was about to go with the GKTwo but wanted to wait to see this review.
I'm not really wanting a large printer. I'm fine with a medium printer. But I do like the heater in the M7 Max but not the screen. (I dont like the M7 Pro, so that one is out) The regular M7 with the plug in heater could do, but I like the flip lid like the GKTwo and M7 Max..Aaarrrgghh.
Can you Ross or anyone help me with the best option I should be looking at? Any advice would be greatly appreciated. Thanks in advance.
Honestly mate, the GK2 is still a killer machine and has benefits over this. you;re talking about a heater, and this still has the best heating method of any machine of this size.
The Gk3 will be better on when shipped than what I have shown here. Not by much, but there will be a few convenience changes, but we also don't know now when these will ship?
So you would recommend going with the GKTwo then? And buying a couple of extra screens. Is the GKTwo still better thean the M7 series?
I am new to Resin printers so I don't have any personal benchmarks to compare to.
Hi @FauxHammer!
I'd like to get the GK3+W230+Cure3 bundle via your recommendation link, so you can get the commision, but i have two questions:
1. When I click on link in description of your video, it takes me to the uniformation main page - will it work, when I choose what I want from there? I mean if you still get the commission?
2. How can I be sure if I get the right voltage and the power cords? When you want to buy W230 separately it ask you if you want the 110V or 220V. I don't see that option, when it comes to the bundle.
Well, this is disappointing... I was definitely thinking that a successor to the GK2 would be on my short list if/when my Saturn 2 packs up, given the quality of life features that the GK2 had I preferred over other printers, but this definitely sounds like something of a step back
It’s a good machine. But smaller screen, and it’s technologically not competitive
Elegoo ultra 4 Perfect
You seen the Ultra 16k?
thats what she said.....
Im really don’t see any reason to get anything other then a Saturn 4 ultra at this point. The price of the ultra is just way to good to consider any other printer of the same size.
How do they justify 1200 bucks for the ‘pro’ version?
1200? Where is that from?
So if there's a resin leak the plastic case will be marred.
Probably. But you’ll see it less in light grey…
