This will be a hot take but I think the community is too conservative with materials. I understand that printed bang sticks are inherently dangerous and it's best to be on the safe side, but there was a guy on reddit who printed launchers out of ASA only and got shit for that despite having working proofs. There even was a guy who posted a beautiful Urutau made from Creality Hyper PLA-CF and claimed over 100 rounds without signs of damage. OG FGC-9 readme calls for plain PLA. That is not something that an average Joe should do, but experiments could lead us to material independent designs. And it would be a good thing, Homeland security can't put everyone who orders any type of filament from Amazon on their watch list.
Well untill the sub got nuked I had about 5 post of ASA frames failing none of them at the layer lines all being through out the layers so it wasn’t bad printing. How ever you are right the commmunity does have a knee jerk on a lot of materials that are fine for certain things how ever a lot of people who have to ask “is this filament good” probably shouldn’t be printing anyway
I went through 2kg of 72D TPU testing it in several different designs. You can find my report on Odysee, but the tldr; is it didn't work - even with design changes. I'm now exploring the capabilities of PCTG (with much better results).
But the bottom line is that some materials have limitations that you just can't design around. PETG, PC, and artistic PLA are always going to be poor choices for most functional firearms parts.
You could multi-material to cover the outside in them
makes the print sky rocket in time. i had a print i was setting up in PLA that i didnt want to have to work too much on removing supports so i was doing PLA and PETG and the print time went from 3 hours to 14 hours. need an IDEX
Yeah that is a downside
