Doing a Cetme C build, and the wood had a train run on it by beavers so I'm gonna 3d print up a new set. Is PLA+ or PETG better for the front handguard and/or stock? If I model a pic rail into the forend will either filament hold up to the clamping load better?I do plan to shoot this gun in below freezing weather if it matters.Also I'm a poor, so will not be melting them with mag dumping as far as heat is concerned, but I
Speaking as someone with zero gun building knowledge but a little 3d printing experience, isn't PLA+ wildly inappropriate for anything that gets prolonged exposed to the sun due to its very low softening point?
>>65252983I've heard it's the UV and moisture that causes problems because it's a bioplastic and those break it down and weaken it.It does have less temperature resistance on paper than PETG in fairness as well though
>>65252983Pla+ is the best filament for guns you can use with a cheap printer. Petg tends to shatter when it fails and is widely cautioned against when printing guns, you might get away with it for furniture but you're better off with pla+. They will both creep from the clamping load but petg tends to squish more and rails are common on 3d gun designed for pla+. All plastic photodegrades in uv not just bioplastic.
