Filaflex TPU 82A

Hi fellow enthusiasts, I am having a major issue trying to setup the correct profile to print TPU 82A filament, please if one of you have managed to successfully print the 82A please send me a copy of your profile setting. When I print TPU 95A with the standard non Generic profile this works fine.

Haven’t tried either, but if TPU95A works for you then TPU82A will just need even slower speeds but should print fine. Take your TPU95A profile and tune the Max Volumetric Speed down.

I have tried that, I found the problem is the filament is getting stuck in the gap between the hot end and the extruder gears

Not good as I just ordered some 70A hardness to try :slight_smile: guess it will have to sit in storage until some mod is developed…

Building up patients to try a couple of more attempts at getting the 82A to print, should be ready in around 6 months LOL

I’m afraid the default tension on the gears in the extruder is going to be too high

When I print very soft TPU on my old printer, I have to lower the tension to almost next to nothing because otherwise the filament (Fiberlogy 30D in this case) gets squished too much, it goes into every hole but the hotend…
When printing other filaments as PLA, ABS,… I had to adjust the tension waay higher or the filaments would just slip inside the extruder

On the Bambu Lab printers, you cannot adjust the tension between the two extruder gears, sadly. That’s why I think it will be impossible to print very flexible TPU’s.

I do not know this for sure. Honestly I have not dared to try the Fiberlogy 30D in my X1C exactly because of this fear. If the tension on the extruder wheels could only be modified.

This got me thinking and started a new thread specifically for tensioning the extruder wheels

I have not been able to use my bambu lab printer yet so I don’t know if this will work on the Bambu lab printer but on my other 3d printers I have used .6 nozzle and set all the line width to .50 and calibrate the flow rate this has help reduce the nozzle pressure and extruder pushing force might be a solution for the bambu lab printer.

All will try this when I receive my 0.6 nozzles in the next 10 Months LOL

I had a roll of 82A filament for a few years, but I was never able to use it on my Ender 3; I couldn’t get nice prints from it. I tried using it on my X1C, and it worked great. I removed the top glass, and the filament hangs on a bar right above the printer and is fed directly into the extruder. In the TPU Bambu profile, I only changed the volumetric speed to 2 mm, and it printed perfectly.
