>Gotta be resin, because of how the layer splicing/fusion works, as well as the mechanical properties you get out of resin that you don't get out of thermomold plastic.
so potentially resin casings will extract and feed reliably? interesting
>Propellant and primers, biggest problem.
not really, I think
you don't really need a lot of muzzle energy or velocity to kill or maim someone, black powder can deliver 200-250 m/s which is enough
barrel grime doesn't matter, though I hope it wont maim the 3d printed receiver if fired from an FGC-9
primer compounds are MUCH easier to make than making NC gunpowder, just mix antimony trisulfide and potassium chlorate, both unregulated
if you cant buy pure antimony trisulfide buy it in its mineral form which I did and it worked
when mixed even in 50/50 it explodes violently upon impact, handle with care, do not mix more than than 30 grains per batch
