Getting the Perfect TPU Settings

I spent quite a while dialing in my TPU settings. I know that they will be different for each printer, but the settings listed here in the video should give you a great starting point. It will also give you an idea of which particular settings to focus on.

IMPORTANT: In the video I state that the fan had very little impact on the quality of the print. After more work, I've discovered that the fan does play a role in layer adhesion for softer TPUs. I found when printing large flat surfaces with the fan speed at 100%, I had layer separation issues on the first couple of layers. I recommend fan sped of 30%-50% to correct for this.

Thank you for the video! I was able to print successfully with TPU with your recommendations

Thank you very much. I really appreciate your video. I used all settings and printing perfect parts. Printing time is long but worth the time for a longer print.

Thanks david for this video. I was able to successfully print my first tpu item on my 3d printer. I struggles so much even at 40mms speed and finally this video was my saviour.

Excellent info and no overly long explanation before diving in! Awesome video

This was the most helpful post I found on TPU. Your settings got me extremely close to what was needed to create a perfect part. I was getting some delayering after the part was half way printed. So, I bumped up the nozzle/ hot end temperature range and increased the bed temperature from 35 C to 40 C after printing the first layer. The parts started coming out with a nice smooth glossy finish with amazing details. Thanks for all of your hard work and for sharing your experience. 😄

the most helpful video i ever watch for tpu printing thank you ♥

[shamelessone]

So glad i found your video.. thank you so much for your settings! I also upped the flow rate by .03 and its coming out quite a bit smoother

[ccmoonie]

thanks for posting this. Helpful, to the point. Having grief with the exact same filament and suspect it needs to be dried more.

Your results are interesting regarding the slopes are interesting. I haven't worked with many TPUs, and I haven't used many benchies with it either, but I just printed one with 3DHOJOR 95A because it was sent to me for my channel, so I'm doing a filament review for it. But The only issues I had printing it on a bambu labs p1p with bambu's default TPU settings in bambu studio is some very light sagging on the absolute overhangs in the cabin's doorways and windows, and of course some light stringing.
There are obviously many factors to why we have this difference, but I just found it interesting.
Another interesting difference is that I have never used a print bed additive for TPU. I currently use a G10 build plate on my p1p and used to use, I think it was called a PEO surface. It's basically a smooth surface with some very light texturing to add a design to the first layer of your print and maybe for adhesion but I'm not for sure about that. But yeah, I have never used any glue or anything for removing the prints. Though looking back it may have helped with some print removals lol. I only used hairspray once when I 3D printed a tool box lid to ensure it would stick throughout the print, which I do with any print that has a large surface area on the build plate.
Good video. Very to the point. Keep up the good work!

Same filament, printing on a K1; excellent information. I had everything really dialed in when I was using the old, old version of Creality Print, but the settings didn't come to the new version and got wiped out anyways.
Time to let this thing cook overnight and hope to see some waaaay cleaner prints.

For removing a large part on the plate putting the plate in the freezer for a few minutes will make it pop right off.

Can you load your profile on makerworld or any other platform? I would be very helpful, I get anxious when I manage the print setting myself, btw I have a p1s printer and the filament is a creality tpu.
Thank you for your guide/tutorial and sorry for my broken English 🙏🏻

Cleaning your part cooling fan might help with the warping. It looks completely clogged with pet hair.

Any tip or trick for smoothening TPU surface?

[Barfly]

Guys. What;s going on? I run a K1 Max, K1 and K2. First layer @60mm/s. Then all others run @100mm/s. All fans set to no more than 20%. Bed @35C and Nozzle @240C using Creality TPU 95A. I found the fans causing way too many clogs and stringing. I got my prints down to 4hrs vs 12hrs. The only other changes i have made is to uncheck everything under Retraction in the Settings Overrides screen EXCEPT Length.
Hope this helps.

could you do a video with PETG for the k1c?
