Any advice printing tpu ?

[peter247]

O.K try again .

First I'll try it Hot 80c , must hotter than my 50c I set it too like PLA .
Than try tape or a covering if that doesn't work all at 50mm/s , which is 13mm/s first layer .

@egon-net What about blue painter's tape ? , not used that for a long time on my printer

Nope. It didn't work. It had to be polypropyplene tape, like the typical transparent packaging tape.

@egon-net I know what you mean now the brown / shiny polypropyplene packing tape

Yes, that tape! That worked for me. All the other materials I tried were like printing eggs on a teflon pan.

@egon-net i am using the Zimple Ziflex PEI powder coated sheet.
it sticks relatively good with a brim.

@danielkrah I already use a PEI sheet, but there's no adherence at all. I end up with the adhesive tape, and it kinda works.

I've only done a few bits for experimentation.

I just used Pritt (white glue stick for paper) and that worked fine, temperatures 70 & 240.

I print Ninjaflex TPU without any problems on glass and carbon.
Never had a problem with sticking. Mostly it sticks to much!

This has been my problem as well. Little bit of glue stick to act as a release agent.

I was originally using buildtak sheets, printing the same item repeatedly in the same location on the bed, got about 20-30 parts. Each part takes 9 hrs to print.
I then switched to garalite G11 3mm sheet 16months ago and still haven’t had to touch up the G11 surface. Best money spent
