>Not very many people specify the type of plastic, PLA and PLA+ won’t last for very long, definitely not thousands and thousands of rounds
They're using PLA+. PETG is a bad idea for a firearm, as I'm sure you know since this you say this is your area of expertise.
Lot of people have thousands of rounds through their printed firearms. Not just .22LR either. Google the Amigo Grande, a .308 rifle. Will they last as long as steel or aluminum? Nah. But they're well beyond where you think they are.
>Those printers are going to be well upgraded and the raw prints carefully cleaned and sanded after. (Again I said specialized like the guy who did an SLS nylon ar lower in the last few days on that Reddit, or well tuned which is still not a trivial task).
There's some sanding involved of course, but lots of people are using completely stock Ender 3's. There are people who go benchy -> glock frame.
>Basically what I’m saying in my original comment is it’s not buy printer download gun go shoot things.
It pretty much is though, and the barrier to entry is dropping week by week.
