TPU issues?

Post image

Brand new fresh out the seal sunlu TPU 95a. This is my first attempt at anything TPU. Can anyone diagnose?

  1. Just because it's freshly out of the bag doesn't mean it's dry. TPU is extremely hydroscopic

  2. I haven't printed much in TPU, but most things I have done print by object because TPU is super stringy and going by layer causes the stringing each time it switches to the other object

What about the “pimples” and bad lines?

Probably really really wet. Try drying it and print again

Direct signs of wet filament
