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.

What is "normal" pa6-cf vs the green one and why isn't this post showing a chart between the two filaments in question? Pa6-cf and pa6-gf.

Based on some very lengthy discussions, both in person and via discord with polymakers material science rep and their director of product development, unless you are playing to dye the filament, there is no reason to use pa6-gf over pa6-cf..if cost is an issue, there are other filaments better suited.

Yeah that chart is a little fucky. It came from a thread discussing PETG-GF vs PA6-CF - and I was curious about the ductility improvements of the GF.

Even at the cost of overall strength. But it seems the brittleness is not that different.
