Why do my TPU prints look like this? - eviltoast

First time printing with TPU. Another problem I had was that it didn’t stick to the textured print bed, had to go for smooth PEI which I read (and now can confirm) is not ideal. Would satin be better?

    Not necessarily. If you don’t hear any sizzle like little pops when extruding you are fine.

    Also watch out for retraction amount and speed. You don’t want more than 1 or 2 mm of retraction at 15mm/s and try to only print that slow as well.

          All depends on your extruder. A decent extruder should have no problems with 200mm/s+

              Just because you can’t get it working doesn’t mean it’s impossible. Vez is printing tpu benchys under 6 minutes, so it’s clearly possible.

                I don’t know what you are talking about. I make real things out of tpu that get used everyday for years. I don’t know who pez is and I’m not interested in bench speed runs.

                  I get that speedbencys aren’t functional objects but as long as you’re not running out of flow rate the material properties shouldn’t differ between 20mm/s and 200
