Scorch is right on the money. Actually, I would say with the correct broach, that a CNC lathe or machining center could rifle a barrel, and I think something similar has been done commercially, but I can't remember who it is that used it. It should be able to cut any twist you want, simply by programming it.
The old stamped steel Liberator was designed to be mass produced, very cheaply, and dropped behind enemy lines for defectors to use in an escape, during WWII. The Liberator 3D printable gun, though, really costs way more to make, over the 3D printer. Plus, there's no plastic, that I know of, yet, that can withstand high pressure, like steel, to use in a barrel or breech block. Fiberglass over a steel sleeve, yes, (Winchester), but not a resin or plastic. I would be afraid to fire an all plastic gun, I value my hand and life way more.
