PA6-CF vs PA6-GF - Impact Toughness vs Brittleness
(fosscad.io)
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.
The differences between CF and GF reinforced PA-6 (within the same brand) are relatively small. Most testing I've seen shows the GF versions to be slightly weaker, but you could likely see just as much performance difference due to ordinary variables (room temperature for your printer, exact moisture content at time of printing, etc.).
Also 2 benefits to the GF is the ability to dye it and the price point.
GF has quite a lot more creep than CF in testing so that should be factored in
