If it's spring driven, then it's not really a firearm. Doesn't mean it's not lethal...but, hell, you can add powerful springs to Nerf guns without 3D printing.)

The AR versions are made with metal and metal parts, but they are made with 3d printed parts as well. The metal parts can be fabricated in another machine that the company sells.
According to
this article. I was referring to "The Liberator"
Quote:
dubbed it “the Liberator” in an homage to the cheap, one-shot pistols designed to be air-dropped by the Allies over France during its Nazi occupation in World War II. Unlike the original, steel Liberator, though, Wilson’s weapon is almost entirely plastic: Fifteen of its 16 pieces have been created inside an $8,000 second-hand Stratasys Dimension SST 3D printer, a machine that lays down threads of melted polymer that add up to precisely-shaped solid objects just as easily as a traditional printer lays ink on a page. The only non-printed piece is a common hardware store nail used as its firing pin.
