I’ve mostly gotten the quality to where I’m happy except for whatever it’s doing to the bow of Benchy. Still some stringing but I don’t expect that to go away completely with TPU. Hatchbox TPU, been lowering temp, lowering print speed, fine tuning retraction, etc. I can give exact numbers if needed, but if anyone knows what to adjust specifically for what it’s doing at the bow that would be great.

      What printer and what orientation did you print these?

      Almost looks like some of the ones I’ve done in abs where I didn’t get proper cooling (turned to have the bow @ 45°, 90° being straight toward the rear of the printer for reference) either from my fan settings or orientation, could try increasing the fan speed? I know you said you’ve dropped the temperature but personally I still find I need to have the part cooling fan on (do print enclosed though so YMMV)

      How dry is the filament, afaik tpu is hygroscopic (been a while since I’ve printed with it unfortunately), I’ve seen messy bow show up on less dry filament, always worth a try anyhow just to remove variables.

        Prusa MK4S, standard Benchy orientation. I haven’t tried adjusting cooling yet, just using the default FLEX settings but I can try that.

    Supports? I’m guessing no, and Ive had issues with TPU and overhangs like the bow there myself. TPU is flexible and thus sags more when printing overhangs.
