Reading through this thread: https://forum.bambulab.com/t/gf-vs-cf-pros-and-cons/192469

What's the consensus on PA6-GF vs CF?

I'm mostly interested in optimizing Super Safety Components like the lever for impact resistance, but also anti-warping.

Currently using PA6-CF. Having solidish results.

PLA+ lever warped (but didn't break) after 450 rounds of .300blk. Very gassy with a can.

Still need to do more solid testing with PA6-CF.

Both material levers break if I smack em with a mallet on an anvil - but that seems like a shitty metric either way.

how does this compare with pla or pla plus?

[–] Kopsis 1 points 1 month ago

Compared to PLA+: 3 - 5x more expensive, much higher heat tolerance, somewhat lower stiffness, needs a 300+°C hot-end, prints best in an enclosure. Strength is comparable (there are differences but it's not dramatically better or worse).

I don't use regular PLA for anything.
