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 :)

Edit 1: First print went well! Got an amazon spool from "Tinmorry" (a brand i've never used before). Glue stick is a must, and i'd recommend some 110%-130% nozzle size extrusion line width (maybe even more). I used a 0.6mm steel nozzle.

I've bought it once from local producer. Printed fine, destroyed my build plate. 😑😑

    Always use a glue stick with TPU. It's used as a release agent, not an adhesive.

    Not knowing this, I once printed TPU directlt on my smooth plate and absolutely destroyed it getting the print off.

    What surface was on the build plate? TPU adheres to some surfaces almost as well as it adheres to itself.

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

    I damaged my stock Snapmaker U1 build plate with a print of 2 layers TPU 85A topped with a solid PETG print.

    TPU 85A only comes off the build plate because you can bend and peel it off. The PETG on top of it stopped me from doing that. It was a dumb idea.
