Since I started 3D printing, I’ve tried out a bunch of different filaments in my projects, from basic PLA to nylon blends. But carbon fiber filament recently caught my attention. I’m excited ...

Here’s a Kickstarter from a few months ago that put carbon fiber in PLA filament, making every desktop 3D printer one that can print in carbon fiber. But perhaps there’s something more here.

The high amount of carbon fibers makes this ... material and lies about half way between PLA and ABS in terms of temperature resistance. Yet, PETG filaments are fairly undemanding to the printer ...
