While NFA items are a different story, you’re generally allowed to manufacture anything you could legally buy in a store. So no suppressors / SBRs / destructive devices without the appropriate paperwork & tax stamps, no machine guns without all that and a time machine, and no fun allowed if you’re a prohibited person. Other than that, there’s nothing* stopping you from printing, say, a semi-automatic rifle with a 16 inch barrel or a glock frame.
*Federally. Also, I am a dumbass and not a lawyer, do your own research.
