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.
That seems like one of those things that ought to be inherently contradictory, but I’ll be interested to hear how it goes. Note that fiber fillings in a material inherently reduce its layer adhesion strength, so your formerly stellar adhesion may not be anymore with the inclusion of the glass fiber. It’ll also make your flexible TPU a lot less flexible. This mitigates the two major advantages of TPU, which leads me to wonder if it’s even worthwhile. But still, give it a go. For science!
Don’t forget to get a hardened steel or gemstone nozzle, otherwise you’ll destroy your brass nozzle in very short order printing with fiber filled materials.
For science! I’ll be ordering a spool from amazon. Heard about the material from the “Lost in Tech” yt channel, was effectively looking for a less fussy nylon-cf.
