I've been playing with carbon+fiber reinforced PET (not PETG) with the X1C. Project pics coming soon.
Holy Hell it's amazing.
Hydroscopic after printing so it's an extremely dimensionally stable even in wet or humid applications, and extremely tough and durable. Way stronger then ABS or conventional PETG, and flexible when thin.
I printed a 2.5mm bar and gave it to my daughter and said, Here try to break this. She folded it over on itself, it will not snap (along the xy plane). After a whole lot of trying everything and flipping it back and forth like a hinge best she could do is tear it.... You can see how it wouldn't fracture.

This is a 1.5mm bar, see how it will bend but not warp, stretch or break.

It will still snap along the z print lines, like if you made an L bracket it could break at the base wo a gusset.
Too bad it's $85/ kilo lol.
