I purchased the TPU Air and and tried printing on my Bambu A1 with a 0.6 mm nozzle but was not successful. What is the recommend filament setting to chose on the Bambu A1 to get this to work? I tried selecting a 90A TPU filament profile.
Any other recommendations for success?
I know there is a separate print profile for the TPU Air you can download on Makerworld. But even with that I couldn’t get the A1 to print it. It just wouldn’t feed it consistently. I ended up printing it on another printer. It is NOT easy to print
@NWCC what printer were you able to print it with?
A custom built. I never tried it in my Qidi printers. That stuff prints super weird. It just pours out of the nozzle lol. But it was pretty easy to clean up after the fact.
For others that may come here…I figured out my issue. The drag of the spool on the standard external spool holder that comes with the A1 is too much causing the nozzle to be starved for filament and creates layers with lots of “air” or “holes”. I printed some parts for a new spool holder with low friction spool and bearings and problems solved!
Jeff,
Great job troubleshooting! glad it worked out
So were you able to print the TPU Air on the A1 successfully? I made modifications to my spool holder also because this happened when printing 95A. I just ordered it and after everything I’m reading I’m conflicted about trying to print it. Thanks
Yes, it worked fine for me after the spool holder modifications. I also downloaded the filament profile from siraya tech for the Bambu A1.
Thank you, I also figured out how to download the file from Siraya Tech. This gives me hope.
If you can get the TPU Air to work, it will be worth it. I just finished printing the first cushion with it and it is so soft. Also the spool seemed expensive, but it did not use very much filament.
I don’t have a Bambu printer so can’t help much, but on my Sovol SV06 ACE I am printing it at 270 C, with the bed at 35 C, Flow Ratio of 0.5, fan at 100% and I set the max volumetric speed to 2 mm/s. I turned off retraction completely, so there is lots of stringing, but I also turned on “Avoid crossing walls” which helps some.
It prints slow but comes out nice.
For the bottom cushion, I flipped the part down so it would print flat on the print bed and wouldn’t need much support. But the headrest is printing vertically (without supports) and the upper cushion will have to be vertical, with supports - there will be stringing, but it seems pretty easy to clean up.
