@@lazyman1011it all comes down to what people are willing to pay for. I work directly with Chinese manufacturers, and they do absolutely amazing work. The problem is people want ultra high quality stuff for the price of the lowest quality stuff, apparently not realizing that those two desires work in opposition to each other and have to be compromised in some direction, either towards higher price or lower quality. Instead of blaming China for making bad stuff, maybe look at home for the forces that are trying to convince you that you should somehow be able to get cheap and high quality. There's the classic engineering adage: fast, cheap, good, choose two. I don't even really think you can reliably take two of those, it's often just one.

The most people are like robots and not allowed to say their opinion or use there brain. Sure cost is one thing and profit optimisation. But quality takes so much effort I design my stuff and let it produce in Europe instead of China. Many fall back to there homecountry or nearby countries after this China experience.

Thank you for doing this test, I watched this a couple of times over the past month or so. I finally just did this upgrade along with the touch and light bar. Note: As of August, the ports seem to be cleaned out, ordered on Amazon if that has anything to do with it.

Probably should have looked at videos like this before buying my Panda jet a couple weeks ago. Must say, I didn't even do a before and after comparison, and just installed it and moved on. Happy to see the PR for this was true. I will for sure be checking mine for blocked ducts after seeing just how clogged yours was. Especially since I've noticed poorer cooling performance on a single consistent side. Great video all up! My P1S also had the OEM duct glued in. One other note, I find the noise produced by the Part Fan to be less irritating with the new Panda Jet duct as well.
Realize video is not new. Have printed a fair amount of BBL Petg CF with really good success, overhangs, etc. Found for BBL petg and pla CF filaments that running Aux fan at 70%, with door wide open, vents in riser open as well(have DK riser), and part positioned at front of build plate next to door opening was able to get by far best results. PLA CF is literally flawless, Petg CF is 99.8% flawless. All of this with stock fan duct. However do believe that I will also try biqu fan duct as every little bit helps. For reference tend to print regular BBL basic and HF petg with door wide open as well with excellent results (excellent quality and layer adhesion). In basment room so ambient air temp is about 68 F, and humidity 35-45%. Dried all filaments heavily and printed from heated dry box.
Very good informational video, thank you. I bought a Q1 Pro from your link when you first reviewed it. Could you make more videos about the Q1 Pro please. I have yet set it up or tried to use it because I was out of town for 6 weeks. Their customer support was great when I contacted them about shipping to the west coast (I live in the upper mid-west). They shipped it within 3 days and kept me informed!! Looking forward to learning the Q1 Pro. Thanks again for the videos.
Nice work. I've added a Panda Jet to my P1S a few weeks ago, and didn't check about ports obstruction. I'm travelling right now, bu as soon as I get back will do that immediately. Thanks for the great evaluation.
It's probably on at least 50% of them, it could be as high as 100% since the process of manufacture is the same. I'd imagine that they go into a tumbler to clear off most of the powder, but it could also be partially a hand process. It's a good thing that they're durable because I gave them some hard whacks off of the bench. I guess a pipe-cleaner would have been a good option now that I think of it... for cleaning pipes. Let me know how it goes, I'm curious if you have the issue too.
@@NeedItMakeIt, just to give a feedback. Returned from my trip, and mine had one duct obstructed. Living in an apartment with no access to an air compressor, rinsed with hot water and blown by mouth was enough to clear it. Tks!
@@NeedItMakeIt I've ordered MJF parts from Shapeways before, and they document it pretty closely; they do it by hand there with an air compressor. I imagine it's probably a pretty similar process for wherever they get their parts from. When you're in a rush to have a lot of throughput though it's easy to miss bits. My Panda Jet that I got the other day had no such problems, so hopefully it shows that BIQU has addressed the issue now.
Top work Mike with an excellent visual presentation of what's going with the airflow. Really well done. Content like this is what will keep people coming back for more. Really good work on identifying the slicer's role in producing good bridging results too. I wonder if Orca slider would do a little better on the bridging when using Monotonic Line for the infill for the layer just above the bridge, as opposed to Rectilinear. I use Monotonic Line myself which doesn't have any portions that run along the bridge line, and I wonder if that small setting difference might help to clean things up a little better?
Thanks for this video. You have been my go to for upgrades/ information since I had a Ender SE V3. Now, I have a P1S =) I bought the Panda Jet and Revo hotend. I know the Revo hotend runs about 10 degrees hotter but with the Panda Jet, I’m wondering how much that will offset the heat increase. Maybe a video with the Revo and Panda Jet would be cool 😎
Funny how you measured the bridging angles in the tests as negative from horizontal (which is zero). All tests I've used measure it as positive from horizontal (so that your -20 degrees is 70 degrees).
I see you have the Qidi Tech Q1 Pro fan initially and state it's the best bang for buck in your description. Could you test to show how the part cooling is performing on this printer and if any mods have / could be designed to improve it?
If it wasn't for making the video and trying to understand it, I would have done the exact same. BIQU responded to my email to say thanks for spotting the problem and that they have made sure to address the problem.
Great look at part cooling fans, I would of said the standard duct on the X1C starts to degrade at 30% as that's where it starts to look different. I too have had some better results on the cheaper filaments sometimes. As we know the colour affects the amount the print shrinks it makes sense that it would also affect bridging too.
Thanks! I suppose I could have gone a lot of further too but I only gave myself 1 week for this video. I'd love to have come up with a better way to measure air pressure right below the nozzle, maybe something digital? Almost like a strain gauge of sorts. I'm not sure if such a devise exists. That's a good point about the color, the color itself is an additive and it only makes sense that it would affect the properties. I'll continue to work on the PETG-CF in grey because I'm pretty sure I can dial it in, for me, I'll never bridge that far anyway, but it's nice to know that it can be done.
Biqu about to get deluged with orders 😂 I just got the BIQU Panda Lux LED Upgrade (they address the 0.3A issue) and it’s fantastic, I would buy this right now but I don’t do much PETG with overhangs.
great video, I thought about getting that very upgrade for my P1S. I would also be very curious to see your take on the panda revo as I have seen both good and bad
I'm so glad I found this video. I installed the Panda Jet on my X1C about a week ago and thought it was horrible compared to the original duct. After watching this and seeing that the outer ducts were clogged with powder, I inspected mine and found it had as much or more powder than yours did. I've been buying Biqu products for years and usually I think they have pretty good quality control but definitely not on these. From what I've read in the comments it's a very common problem. Makes you wonder how many of these were returned or just thrown into a drawer because those people thought they were junk or just a "gimick". Biqu should address this problem. Thank you for bringing this issue to my attention.
I'll have to email them again because I was told that they'd correct the problem. It could be that the one you bought was already packaged by the time I made the video, but I'd like to follow up anyway.
@@NeedItMakeIt I really appreciate that. I did have it sitting around for a couple weeks before I installed it, so I guess it was maybe 3 weeks ago that I received it. I've done a few prints since clearing the powder and it's a noticeable improvement now.
Great video. I have some thing to add. I have printed petgcf exclusively for over a year and thousands of parts with some of the hardest bridges to make -curved overhangs. I struggled with the these overhangs and bridges right up until production at the print farm. The solution was no more than 50% overhang on the inside circle overhang, and bridges you need to slow down the speed settings in the slicer. In Orca your overhang speeds should go down in this order - 73-30-30-15-15-20. Then you need to turn on extrusion rate smoothing to 350. This causes the extruder to slow down in a ramped fashion just before the bridge and allows the filament to stick to the launch point(spot where the bridge starts over the air) and drag the line across while giving enough time for cooling. It's also important to check how the part is being sliced in detail. Make sure the slicer is pulling straight lines across the bridge in dark blue, not solid infill lines in light blue that zigzag. This becomes important when the part geometry changes or it's orientation on the bed does as the infill patterns always face the same direction across the bed. And one last thing - use a z.offset of 0.03-0.05 to prevent curling or blobbing at the nozzle.
Great work. Congrats. I would be very interested in seeing other extruders catalogged like this. I got a. Voron and with stealth burner, always thought the air flow are weak and offset. Would be nice to see it like you show with the water and cameras
Great video … again. Another printer I am hearing a lot about is the FlashForge Adventure 5m and Pro. Not sure they are better than the Qidi or X1C but the 5M is no where the price. I have heard it called the poor man’s Bambu. lol. But it seems to have excellent printing. Might be a good one to check out.
This episode is why I subscribed. Thank you. NOTE: I wonder if the BambuLab would be further improved if the fan is modeled more towards the Ender-style fan. And I wonder if the Ender can be improved with a different type of port exhaust?
Bought and installed 8 of these for that slight improve to PLA, and seen absolutely no difference. Seems like all of them have great flow through the ducts, not sure if I'm doing something wrong
I'm about to pair this fan shroud up with the "Fully Assembled High Flow ObXidian™ HotEnd for Bambu Lab X1/P1 Series" by E3D for some serious high-speed printing. With that hotend you can easily go from 12 to 30+ mm3/sec for the volumetric flow rate so I'll really be able to spit out the filament.
Definitely seems like a worthwhile modification, kind of makes you wonder why the things weren't just made with this since they seem to have thought of everything else so well 🤷🏿♀️
I wonder how the black CFPETG would have done on the e3. I'm super glad you tried the other color. That was the first thing I thought about the bridging test, "I wouldn't be so sure the colors will behave the same." To be clear: it's the pigment mix that makes the difference. Maybe a different pigment (or a different amount of the same pigment) used to make black filament could perform even better than the red. 🤷 Similarly, maybe there's a way to make the same shade of red, but make the bridging perform worse due to a different pigment.
That makes sense, until I tested PETG-CF in a proper bridge test the difference didn't seem to be there, but it certainly was. I can always go further in my testing, but I only give myself 1 week per video, ideally I'd do 2/wk some videos take longer than others and this one took quite a bit longer than I was expecting. I'll be sure to keep this in mind for any future testing videos for PETG-CF the bridge settings and cooling do have an impact on real parts and it has been a bit of a pain to have near perfect prints except for the bridged areas. That problem should be a thing of the past.
I should have mentioned in my first post: thanks for the great video! I learned several ways of visualizing airflow I hadn't seen before. I'll definitely be putting them to good use.
i got a pandajetpack today installed it and after calibrating i was wondering where all this rust looking stuff came from on my build plate. now i know
The BQ is the worse I've tested, surprising you obtain better results than with stock. The big issue with these aftermarket fan duct is that you cannot remove them during print when head is above poop funnel.
I don't think you can compare the relative strength of the air flow in the way you are doing. These centrifugal blowers are designed to create *pressure*, not air flow. If the smaller outlet gets more of the directional airflow, it's going to develop a higher pressure which then applies back pressure to the incoming air stream, which will then direct more towards the other outlet. It won't reach a perfect balance, but it's not simply a matter of balancing or directing the air stream. The new one definitely looks better though, much better balanced. And the colour and fillers do indeed matter!
Also. Saw a video talking about wall line order, as inner/outter/inner being the best for part quality and overhang, but I can't get it on my mind how come. Would be nice to see a comparison and study from you.
I saw another review of this duct (I think) and it didn't have as good of result - but I bet theirs was clogged and they didn't realize it! This duct seems nice and I might upgrade my machines, but I am even more surprised how good the Creality cooling is. It's weird to see them actually stepping up, finally.
With all ports open it works better than I was expecting, quite a bit better actually. Before I mounted it I wasn't sure where it was going to put the air in relation to the nozzle, but it turned out great. If I hadn't remove the clog, it would have been a disaster for sure. I don't blame anyone for not catching it, I just happened to me taking quite a bit of time to test out the flow and when I blew into it with my mouth at first, no air was coming from the 2 ports... I showed the little blower, but I used my lips the first time... tasty nylon powder :) I would have loved to have a tiny camera to get inside there and see where the clogs were exactly, but I had no such camera that would fit. In any case, BIQU is aware of the problem and so is everyone who may want one in the future. Creality still falls short on the overall print quality, but is quite a bit better on cooling, and that was my experience with the K1 compared to the X1C as well. Bambu usually has a reason for their decisions, but in this case I can't think of a good one, it seems like they just didn't put quite as much thought into it as they could have.
Amazing and helpful video! Looking for a good cooling upgrade solution for the Ender 3 V3 KE. I'm trying to print a spring-like 3d model, with very thin diameter, and the cooling there is crucial. External fans (or fan ducts pointing to the bed) actually can help? maybe this can be tested on a future video? Thanks, and keep with the good work! 🙌
could you link the 4-way bridging test used in the video please? It looks very useful. too many tests out there have the obtuse angle marked instead of the acute angle.
Ouch, that's some terrible QC from BIQU. Quite a bad practice. For $30 you may expect better than that. Anyway, great video! I love the thorough workflow you use and the way of showing the results. Your calm but clear way of presenting is also really nice. It's a refreshing and welcome break from the typical overly hyper personalities that are so popular in streaming and such nowadays, for whatever mysterious reason.
It's something that FDM does better than other more professional methods of 3D printing, at home I wouldn't need to worry about clearing the ducts At least BIQU was good about it, they responded and they've addressed the QC issues. The funny part is that I read some not so positive comments before I made the video, and after finding this problem, the comments made a lot of sense. For the cost of a pipe-cleaner, it would have done the job to clear those. I believe with the process they use the parts are blasted with a medium from the outside to clean them off, and possible a vibratory tumbler too. I still like what they did, but they probably had a few unhappy customers upfront because of this before it was caught. Thanks for the feedback! I'm always trying to improve my skills, I'm not a "natural" let's say and I certainly don't want to change my personality for the camera, I hope to get a little more comfortable in front of the camera, it's not like speaking to a person of course, it's like speaking to... a camera, which should seem strange to most people unless you grew up with a smart phone I suppose. My best guess is that our attention spans have become very short with the constant flood of information and "shiny" things, I can't really say for sure though and I am curious to know what happens to our species in the future. Thanks for the support and the conversation, have a great night!
Excellent video! (Already a subscriber, this time I clicked the bell, making you a member of a very elite club. 👍😁) Excellent catch about the powder-clogged ports, I wouldn’t have caught that myself, now I’ll know to check before I install it. (Yes, I’m going to order one 😁) Also very interesting note about bridging in Orca Slicer, maybe I’ll finally switch :-)
If the original one is glued, then BiQu could send their own version of cover, or create a stl for one so we could print it. But it still seems that cooling is a thing that can be upgraded, but not sure if BiQu parts are good enouth with this quality - especially that we do have tools to create our own ducts?
Don't have any empirical evidence, but when my Ender 3 S1 Pro's part cooling fan failed, I switched to a blower and a trihorned duct and saw a marked difference in overhang quantity.
It's no easy task, I was thinking about a macro lens, but that's only useful at slow speeds, and slow speeds mean better cooling, so it's not going to allow us to test it well in reality. I was thinking about using something that simulated grass too. I think the best thing is just long-term testing. I think the blower like you did is close to the best, we can also move to the CPAP blower design and sit the fan up and away with a hose to feed the ducts for part cooling. I'd like to try that as well down the line.
@@NeedItMakeIt I just saw the CPAP on a video from RMRRP. I think that is an awesome concept. Get the weight off the extruder and outside air would be cooler.
Do you check temperatures with K-type thermocouple? Thermistors on different printers can have different temperatures. 245°c on different Bambu printers that I have actually have different temperatures.
I cannot post links but the video "3d printing bridges profile tuning" shows how to improve bridges when standard settings don't work. Maybe try that on the poorest bridges you got!
Unfortunately, I cannot confirm the results with my X1C. The overhangs and bridges with the Panda Jet look significantly worse than with the original Bambu Fan Duct
You blew that issue up, pretty big, I guess. Modding the parts cooling is one of the first mods I usually do, you can allways turn the fan down, if needed. Good to see a solution for bamboo printers, that helps with that.
Would this duct be a good combo with Panda Revo for X1C nozzle? Some people reported that because the Revo has that big thing around nozzle it actually blocks the air so the part cooling is worse wit stock fan duct
Im interested in this upgrade, but that left over powder inside has me very hesitant. I don't have an air compressor to remove gunk like that, and I especially don't want this kind of gunk going into my prints. Is this kind of post factory stuff in every unit?
Thank you. Definitely would like to see the install of BIQU light bar. Lots of conflicting information out there with respect to running the stock and Panda Lux simultaneously. Hopefully you can shed some honest light here 😉
I just received it- it’s great. And NO you should not run it with the stock light. There’s zero conflicting information from official sources because both Bambu Lab and Biqu acknowledge that the max output is 0.3A. So you can either run the Panda Lux OR the stock light, but not both. The confusion stems from the fact that the lux includes a splitter and additional wire to run them both, for those who want to take the risk. BBL says don’t risk it, and BIQU concurs and informs consumers on the website, in the insert in the packaging, and on their official installation video (it’s on TH-cam just search for panda lux). So that’s the final word. Also it looks great.
@@aeonjoey3d Thanks. Not sure why people want to run both, looks like the upgrade kit would provide more than enough light (compared to stock). Got one on order.
Not everyones Tool head port will have the same amount of glue fixing it to the cover and so the cover maybe damaged during removal, also I don't want to have to clean out the excess powder from a part I have paid good money for. Until there are QC changes made I will not be buying this upgrade. I checked out my X1C port and it is also glued in to the cover, by the amount of excess glue it looks like they used either a 3" brush or a cat to apply it, they got that stuff everywhere!
I understood that all of these were from Virgin material, but you could be right, I'd have to read the fine-print. Most of this was a surprise since I've never attempted to bridge this material before, bridging with PLA or ABS are both pretty easy in comparison, but PETG is not like the others.
19:23 I hope you learned that any tests must be fobe on the very same filament. Not a different color, not even a different roll. And if you print multiple pieces with each printer then alternate between printers, so you print a few pieces with one, then the same parts with the other printer, and the next few pieces with the first printer, then with the other, etc. Just so you avoid the possibility of the filament being inconsistent (e.g., maybe it's absorbing moisture while printing, so latter parts are worse).
Man, the glue on my toolhead cover was EXTREMELY difficult to remove. The stuff is so hard a knife barely scratches it - is it steel powder reinforced epoxy or something? Even after an hour of very carefully scraping it off, one of the catches for the clips broke off anyway - nothing a bit more glue can't fix, though! Anyone got any tips for making this process easier?
I'm with you on that one, they really did not want it coming off! The dentist tools worked wonders for me, but there may be a solvent that would soften it a bit.
Ha, sounds like Creality did more research on the cooling then Bambu did. Of course Creality also just has more experience mostly building the same machine over and over 😁
if they made something different every time no one would buy their products. There's such thing as a design that doesn't need changing because people still want it, not necessarily because it can't be improved.
@@shamancredible8632 I own a KE, I get it. Flashforge comes to mind when you mention different products. Good stuff, that nobody buys. Then again it looks like they've shrunk their product line lately.
Thanks for the video. Was this a sponsored video? When a company is providing a product for free and a quick ad plug for their other products is at the end of the video… Did you have any talking points? Were you compensated beyond the free product? What agreements, if any, exist between you and Biqu? I appreciate the video and see the results. Additionally, when channels are smaller, it’s important to be really clear about what is your honest opinion vs what is sponsored and a talking point.
Okey, now I go and smash my Panda Jet on the table 😂 For now i'm not impressed by the Panda 😕 Your settings as example where interessting for the bridging test
The fact that you had to clear out all that junk just smacks of really poor quality control. As a result I’d be very unlikely to purchase this new part. Honestly I would have just installed it only to find out it didn’t pass the cooling air as described and have wasted all that work. So they get a big nope from me.
First time I see a camera below the water. Genius.

Thanks for this video. You have been my go to for upgrades/ information since I had a Ender SE V3. Now, I have a P1S =) I bought the Panda Jet and Revo hotend. I know the Revo hotend runs about 10 degrees hotter but with the Panda Jet, I’m wondering how much that will offset the heat increase. Maybe a video with the Revo and Panda Jet would be cool 😎
Funny how you measured the bridging angles in the tests as negative from horizontal (which is zero). All tests I've used measure it as positive from horizontal (so that your -20 degrees is 70 degrees).
Might be because it’s how Bambu Studio and Orca measure overhangs as the former, even though most users do the latter
@@aeonjoey3d I should've known :D Bambu Studio, doing things differently since 202X.
Very informative. Good call on the blocked ports. Looking forward to your next video.
I see you have the Qidi Tech Q1 Pro fan initially and state it's the best bang for buck in your description. Could you test to show how the part cooling is performing on this printer and if any mods have / could be designed to improve it?
Great job checking the ports. I know I would have just slapped in the part and then get more frustrated. 😊
If it wasn't for making the video and trying to understand it, I would have done the exact same. BIQU responded to my email to say thanks for spotting the problem and that they have made sure to address the problem.
Great look at part cooling fans, I would of said the standard duct on the X1C starts to degrade at 30% as that's where it starts to look different. I too have had some better results on the cheaper filaments sometimes. As we know the colour affects the amount the print shrinks it makes sense that it would also affect bridging too.
Thanks! I suppose I could have gone a lot of further too but I only gave myself 1 week for this video. I'd love to have come up with a better way to measure air pressure right below the nozzle, maybe something digital? Almost like a strain gauge of sorts. I'm not sure if such a devise exists. That's a good point about the color, the color itself is an additive and it only makes sense that it would affect the properties. I'll continue to work on the PETG-CF in grey because I'm pretty sure I can dial it in, for me, I'll never bridge that far anyway, but it's nice to know that it can be done.
Biqu about to get deluged with orders 😂 I just got the BIQU Panda Lux LED Upgrade (they address the 0.3A issue) and it’s fantastic, I would buy this right now but I don’t do much PETG with overhangs.
great video, I thought about getting that very upgrade for my P1S. I would also be very curious to see your take on the panda revo as I have seen both good and bad
Nice video. And you're right. The color and humidity of the filament affect the print.
I'm so glad I found this video. I installed the Panda Jet on my X1C about a week ago and thought it was horrible compared to the original duct. After watching this and seeing that the outer ducts were clogged with powder, I inspected mine and found it had as much or more powder than yours did. I've been buying Biqu products for years and usually I think they have pretty good quality control but definitely not on these. From what I've read in the comments it's a very common problem. Makes you wonder how many of these were returned or just thrown into a drawer because those people thought they were junk or just a "gimick". Biqu should address this problem. Thank you for bringing this issue to my attention.
I'll have to email them again because I was told that they'd correct the problem. It could be that the one you bought was already packaged by the time I made the video, but I'd like to follow up anyway.
@@NeedItMakeIt I really appreciate that. I did have it sitting around for a couple weeks before I installed it, so I guess it was maybe 3 weeks ago that I received it. I've done a few prints since clearing the powder and it's a noticeable improvement now.
@NeedItMakeIt i just got one off amazon and it has the clogged problem. I bought the full panda jetpack instead of just the panda jet
Great video. I have some thing to add. I have printed petgcf exclusively for over a year and thousands of parts with some of the hardest bridges to make -curved overhangs. I struggled with the these overhangs and bridges right up until production at the print farm. The solution was no more than 50% overhang on the inside circle overhang, and bridges you need to slow down the speed settings in the slicer. In Orca your overhang speeds should go down in this order - 73-30-30-15-15-20. Then you need to turn on extrusion rate smoothing to 350. This causes the extruder to slow down in a ramped fashion just before the bridge and allows the filament to stick to the launch point(spot where the bridge starts over the air) and drag the line across while giving enough time for cooling. It's also important to check how the part is being sliced in detail. Make sure the slicer is pulling straight lines across the bridge in dark blue, not solid infill lines in light blue that zigzag. This becomes important when the part geometry changes or it's orientation on the bed does as the infill patterns always face the same direction across the bed. And one last thing - use a z.offset of 0.03-0.05 to prevent curling or blobbing at the nozzle.
These notes and parameters refer to which printer?
@@CreativeDesign75CZ P1p with all hardened steel parts.
Great work. Congrats. I would be very interested in seeing other extruders catalogged like this. I got a. Voron and with stealth burner, always thought the air flow are weak and offset. Would be nice to see it like you show with the water and cameras
Great video … again. Another printer I am hearing a lot about is the FlashForge Adventure 5m and Pro. Not sure they are better than the Qidi or X1C but the 5M is no where the price. I have heard it called the poor man’s Bambu. lol. But it seems to have excellent printing. Might be a good one to check out.
Would be nice to see a follow up vid with bridge setup dial in.
Best possible cooling video on the internet! Pure gold man :)
This episode is why I subscribed. Thank you.
NOTE: I wonder if the BambuLab would be further improved if the fan is modeled more towards the Ender-style fan. And I wonder if the Ender can be improved with a different type of port exhaust?
Please test the Ben2C Nautilus !
Maybe try their toolhead plate replacement and see if it makes any difference
Bought and installed 8 of these for that slight improve to PLA, and seen absolutely no difference. Seems like all of them have great flow through the ducts, not sure if I'm doing something wrong
I'm about to pair this fan shroud up with the "Fully Assembled High Flow ObXidian™ HotEnd for Bambu Lab X1/P1 Series" by E3D for some serious high-speed printing. With that hotend you can easily go from 12 to 30+ mm3/sec for the volumetric flow rate so I'll really be able to spit out the filament.
I don't generally like to 'upgrade'or mod my printer, but this actually seems like it's worth it, especially if it's inexpensive.
Definitely seems like a worthwhile modification, kind of makes you wonder why the things weren't just made with this since they seem to have thought of everything else so well 🤷🏿♀️
I wonder how the black CFPETG would have done on the e3.
I'm super glad you tried the other color. That was the first thing I thought about the bridging test, "I wouldn't be so sure the colors will behave the same."
To be clear: it's the pigment mix that makes the difference. Maybe a different pigment (or a different amount of the same pigment) used to make black filament could perform even better than the red. 🤷 Similarly, maybe there's a way to make the same shade of red, but make the bridging perform worse due to a different pigment.
That makes sense, until I tested PETG-CF in a proper bridge test the difference didn't seem to be there, but it certainly was. I can always go further in my testing, but I only give myself 1 week per video, ideally I'd do 2/wk some videos take longer than others and this one took quite a bit longer than I was expecting. I'll be sure to keep this in mind for any future testing videos for PETG-CF the bridge settings and cooling do have an impact on real parts and it has been a bit of a pain to have near perfect prints except for the bridged areas. That problem should be a thing of the past.
I should have mentioned in my first post: thanks for the great video!
I learned several ways of visualizing airflow I hadn't seen before. I'll definitely be putting them to good use.
Great video, the water really helped with the visuals great idea.
I wonder if the movement of the bed on the v3 makes a difference to bridging?
i got a pandajetpack today installed it and after calibrating i was wondering where all this rust looking stuff came from on my build plate. now i know
The BQ is the worse I've tested, surprising you obtain better results than with stock. The big issue with these aftermarket fan duct is that you cannot remove them during print when head is above poop funnel.
I don't think you can compare the relative strength of the air flow in the way you are doing. These centrifugal blowers are designed to create *pressure*, not air flow. If the smaller outlet gets more of the directional airflow, it's going to develop a higher pressure which then applies back pressure to the incoming air stream, which will then direct more towards the other outlet. It won't reach a perfect balance, but it's not simply a matter of balancing or directing the air stream.
The new one definitely looks better though, much better balanced. And the colour and fillers do indeed matter!
Also. Saw a video talking about wall line order, as inner/outter/inner being the best for part quality and overhang, but I can't get it on my mind how come. Would be nice to see a comparison and study from you.
The X1C seems to struggle with PETG in general has been my experience
I saw another review of this duct (I think) and it didn't have as good of result - but I bet theirs was clogged and they didn't realize it!
This duct seems nice and I might upgrade my machines, but I am even more surprised how good the Creality cooling is. It's weird to see them actually stepping up, finally.
With all ports open it works better than I was expecting, quite a bit better actually. Before I mounted it I wasn't sure where it was going to put the air in relation to the nozzle, but it turned out great. If I hadn't remove the clog, it would have been a disaster for sure. I don't blame anyone for not catching it, I just happened to me taking quite a bit of time to test out the flow and when I blew into it with my mouth at first, no air was coming from the 2 ports... I showed the little blower, but I used my lips the first time... tasty nylon powder :) I would have loved to have a tiny camera to get inside there and see where the clogs were exactly, but I had no such camera that would fit. In any case, BIQU is aware of the problem and so is everyone who may want one in the future. Creality still falls short on the overall print quality, but is quite a bit better on cooling, and that was my experience with the K1 compared to the X1C as well. Bambu usually has a reason for their decisions, but in this case I can't think of a good one, it seems like they just didn't put quite as much thought into it as they could have.
Amazing and helpful video!
Looking for a good cooling upgrade solution for the Ender 3 V3 KE. I'm trying to print a spring-like 3d model, with very thin diameter, and the cooling there is crucial. External fans (or fan ducts pointing to the bed) actually can help? maybe this can be tested on a future video?
Thanks, and keep with the good work! 🙌
Could you point to the bridging test you were using in the video, did not come across this one before ... thanks
My Panda jet just came in today. Can't wait to install it and test it out!
could you link the 4-way bridging test used in the video please? It looks very useful. too many tests out there have the obtuse angle marked instead of the acute angle.
I'd noticed the side of prints closest to the left of the x1c printer were slightly nicer. I had assumed it was the chamber fan.
I'm curious if the new fan duct weighs more. It looks heavy. Otherwise, good content!
weighs 0.2g more than the genuine one
Excellent video thank you. Love the water test awesome idea visualization of the invisible
Ouch, that's some terrible QC from BIQU. Quite a bad practice. For $30 you may expect better than that.
Anyway, great video! I love the thorough workflow you use and the way of showing the results. Your calm but clear way of presenting is also really nice. It's a refreshing and welcome break from the typical overly hyper personalities that are so popular in streaming and such nowadays, for whatever mysterious reason.
It's something that FDM does better than other more professional methods of 3D printing, at home I wouldn't need to worry about clearing the ducts At least BIQU was good about it, they responded and they've addressed the QC issues. The funny part is that I read some not so positive comments before I made the video, and after finding this problem, the comments made a lot of sense. For the cost of a pipe-cleaner, it would have done the job to clear those. I believe with the process they use the parts are blasted with a medium from the outside to clean them off, and possible a vibratory tumbler too. I still like what they did, but they probably had a few unhappy customers upfront because of this before it was caught.
Thanks for the feedback! I'm always trying to improve my skills, I'm not a "natural" let's say and I certainly don't want to change my personality for the camera, I hope to get a little more comfortable in front of the camera, it's not like speaking to a person of course, it's like speaking to... a camera, which should seem strange to most people unless you grew up with a smart phone I suppose. My best guess is that our attention spans have become very short with the constant flood of information and "shiny" things, I can't really say for sure though and I am curious to know what happens to our species in the future.
Thanks for the support and the conversation, have a great night!
Excellent video! (Already a subscriber, this time I clicked the bell, making you a member of a very elite club. 👍😁)
Excellent catch about the powder-clogged ports, I wouldn’t have caught that myself, now I’ll know to check before I install it. (Yes, I’m going to order one 😁)
Also very interesting note about bridging in Orca Slicer, maybe I’ll finally switch :-)
If the original one is glued, then BiQu could send their own version of cover, or create a stl for one so we could print it.
But it still seems that cooling is a thing that can be upgraded, but not sure if BiQu parts are good enouth with this quality - especially that we do have tools to create our own ducts?
I'd love to see how this compares to the BEN2C Nautilus fan duct. I can't find anyone doing a review on it yet.
Don't have any empirical evidence, but when my Ender 3 S1 Pro's part cooling fan failed, I switched to a blower and a trihorned duct and saw a marked difference in overhang quantity.
It's no easy task, I was thinking about a macro lens, but that's only useful at slow speeds, and slow speeds mean better cooling, so it's not going to allow us to test it well in reality. I was thinking about using something that simulated grass too. I think the best thing is just long-term testing. I think the blower like you did is close to the best, we can also move to the CPAP blower design and sit the fan up and away with a hose to feed the ducts for part cooling. I'd like to try that as well down the line.
@@NeedItMakeIt I just saw the CPAP on a video from RMRRP. I think that is an awesome concept.
Get the weight off the extruder and outside air would be cooler.
the video quality of this! so thorough through the subject!
can you test the other upgrades for from bq like panda claw and extruder
Has Bambu published any drawings of their parts, like those fan ducts?
I wish you would have compared with a CPAP system, is it really a game changer ?!
I wonder how high can you crank everything up with this and an obxidian nozzle.
Based on the comparison video fromDIY PERSPECTIVE the Q1 also has subpar cooling compared to P1S. I wonder, since the design seems similar.
Thanks for this video! It resulted in an instabuy of the "PANDA JET". 😃
Do you check temperatures with K-type thermocouple? Thermistors on different printers can have different temperatures. 245°c on different Bambu printers that I have actually have different temperatures.
Donyou need to reapply adhesive when installing the panda jet?
Great guide - just ordered a piece for me to try on my P1S
petg-cf ahs been kicking my butt on a big print for over a month :)
can you please test this against the ben2c nautilus duct!
I cannot post links but the video "3d printing bridges profile tuning" shows how to improve bridges when standard settings don't work. Maybe try that on the poorest bridges you got!
Unfortunately, I cannot confirm the results with my X1C. The overhangs and bridges with the Panda Jet look significantly worse than with the original Bambu Fan Duct
Here bc I'm having exact same issue.
You blew that issue up, pretty big, I guess.
Modding the parts cooling is one of the first mods I usually do, you can allways turn the fan down, if needed.
Good to see a solution for bamboo printers, that helps with that.
Would this duct be a good combo with Panda Revo for X1C nozzle? Some people reported that because the Revo has that big thing around nozzle it actually blocks the air so the part cooling is worse wit stock fan duct
Im interested in this upgrade, but that left over powder inside has me very hesitant. I don't have an air compressor to remove gunk like that, and I especially don't want this kind of gunk going into my prints. Is this kind of post factory stuff in every unit?
Thank you. Definitely would like to see the install of BIQU light bar. Lots of conflicting information out there with respect to running the stock and Panda Lux simultaneously. Hopefully you can shed some honest light here 😉
I just received it- it’s great. And NO you should not run it with the stock light. There’s zero conflicting information from official sources because both Bambu Lab and Biqu acknowledge that the max output is 0.3A. So you can either run the Panda Lux OR the stock light, but not both. The confusion stems from the fact that the lux includes a splitter and additional wire to run them both, for those who want to take the risk. BBL says don’t risk it, and BIQU concurs and informs consumers on the website, in the insert in the packaging, and on their official installation video (it’s on TH-cam just search for panda lux). So that’s the final word.
Also it looks great.
@@aeonjoey3d Thanks. Not sure why people want to run both, looks like the upgrade kit would provide more than enough light (compared to stock). Got one on order.
Not everyones Tool head port will have the same amount of glue fixing it to the cover and so the cover maybe damaged during removal, also I don't want to have to clean out the excess powder from a part I have paid good money for.
Until there are QC changes made I will not be buying this upgrade.
I checked out my X1C port and it is also glued in to the cover, by the amount of excess glue it looks like they used either a 3" brush or a cat to apply it, they got that stuff everywhere!
Did you leave the lid/door open?
Did you ever test with top glass taken off of the X1?
I haven't been lately no, is there something you'd like to test for?
Little info for the dust in the new cooling part: they solved it :-) - i bought one a week ago and there was no dust anymore in the cooling part.
Have to imagine this will be fixed on their next iteration
Right! You know BBL watched this video with chagrin at the Creality water test vs theirs
Isn’t black likely to perform worse since it tends to be made with re-grind plastic?
I understood that all of these were from Virgin material, but you could be right, I'd have to read the fine-print. Most of this was a surprise since I've never attempted to bridge this material before, bridging with PLA or ABS are both pretty easy in comparison, but PETG is not like the others.
Impressive test 👍😃
Try reducing bridge flow to .80 or .75 will improve you're bridging dramatically
do you tink havving the bridgetests so thin/ close to the bed makes the test unprecise or nah?
yes i think that overhangs and bridges close to the bed are afected more or less in open or closed printer and AUX fan can help for this
I'm trying to access your discord but am unable to. Is the link in the description not functional?
a flow test and calibration might have played a role in the tests, over extrusion will defiantly make overhangs worse
Please review panda Revo
19:23 I hope you learned that any tests must be fobe on the very same filament. Not a different color, not even a different roll. And if you print multiple pieces with each printer then alternate between printers, so you print a few pieces with one, then the same parts with the other printer, and the next few pieces with the first printer, then with the other, etc. Just so you avoid the possibility of the filament being inconsistent (e.g., maybe it's absorbing moisture while printing, so latter parts are worse).
Man, the glue on my toolhead cover was EXTREMELY difficult to remove. The stuff is so hard a knife barely scratches it - is it steel powder reinforced epoxy or something? Even after an hour of very carefully scraping it off, one of the catches for the clips broke off anyway - nothing a bit more glue can't fix, though!
Anyone got any tips for making this process easier?
I'm with you on that one, they really did not want it coming off! The dentist tools worked wonders for me, but there may be a solvent that would soften it a bit.
The no-brand PET-G Carbon fibre probably has next to no carbon fibre in it, which is why it did well.
Your share a sale link doesn't work. It says connection refused.
comment for the algorithm
was a great video
Ha, sounds like Creality did more research on the cooling then Bambu did. Of course Creality also just has more experience mostly building the same machine over and over 😁
if they made something different every time no one would buy their products. There's such thing as a design that doesn't need changing because people still want it, not necessarily because it can't be improved.
@@shamancredible8632 I own a KE, I get it. Flashforge comes to mind when you mention different products. Good stuff, that nobody buys. Then again it looks like they've shrunk their product line lately.
15:51 I hope you're wearing respiratory protection, as that powder's gotta be horribly bad to inhale.
Thanks for the video.
Was this a sponsored video? When a company is providing a product for free and a quick ad plug for their other products is at the end of the video… Did you have any talking points? Were you compensated beyond the free product? What agreements, if any, exist between you and Biqu?
I appreciate the video and see the results. Additionally, when channels are smaller, it’s important to be really clear about what is your honest opinion vs what is sponsored and a talking point.
Okey, now I go and smash my Panda Jet on the table 😂
For now i'm not impressed by the Panda 😕
Your settings as example where interessting for the bridging test
On BBL X1C
Great video. 👍👍🙏🙏
"3D Printing Ultimate Bridging vacuum duct Crazy idea" search for thid
christ their QC is bad, imagine all that powder blowing out all over your printer/room/lungs
The fact that you had to clear out all that junk just smacks of really poor quality control. As a result I’d be very unlikely to purchase this new part. Honestly I would have just installed it only to find out it didn’t pass the cooling air as described and have wasted all that work. So they get a big nope from me.
