Hi y'all!

I've been wanting to have a go at tpu-gf. I mostly print mechanical parts, so reinforced tpu with its stellar layer adhesion seems very intriguing! Does anyone here have any experience with printing Glassfibre-filled TPU? How did it go?

Also, are there any shops selling it within the EU?

Greetings, Waffle :)

Standard PEI build plate, I've printed normal TPU before and it was somewhat hard to take off, but not to this degree.

Oh dear, noted. Think i'll layer some gluestick on my buildplate as a cheap releaser

Isopropyl alcohol. a little dab under the print will help it come loose.

Though it is best to use a release agent with TPU, like a glue stick.
