Hi, I’m new to 3D printing, I printed only 200h but mostly with PETG, PLA and ASA and had no significant issues. However, I tried to print with TPU (4-5 different makers) and all gave bubbles on the arch part of the part I’m trying to print. The filament is dried 7-8h each. Tried to play with printing them, and cooling temperatures, but unfortunately, no luck. Do you know what could be the issue?
If you have tried different TPU brands, and they all fail in the same fashion, could it be the model?

I have printed the same model with PETG, PCTG, ASA without any issues.
I believe the issue is with the model but I’m not sure how to rectify and keep the same shape.
I was hoping that someone had a similar issue with the curve/arch part of the model and had found a solution.
I misunderstood then. My thought goes towards top layers then.
Meaning the number of them.

Slow down the overhang speeds and more top layers, I see overhangs warping there. Other materials do overhangs with good cooling better.
