Meet The 'Liberator': Test-Firing The World's First Fully 3D-Printed Gun

[MineralMan]

20. And you're right to have those doubts.

But, it doesn't matter, really. This plastic thing and most zip guns are meant to be used at point-blank range, anyhow. Accuracy and the ability to fire multiple rounds aren't really issues at all for such weapons. They're throwaways to begin with.

The only thing unique about this printed single-use weapon is that it's printed. I can, and have, made a .25 ACP single-use zip gun with nothing but materials purchased at my local Ace Hardware. The only tool needed was an electric drill and a couple of drill bits. It took me less than half an hour to assemble the thing, which fired just fine the first time.

The difference was that I didn't need an $8000 3D printer to accomplish this. I made it to win a $20 bet with a guy who said it couldn't be done. I didn't hold the thing when it was test-fired, but it clearly demonstrated that I could have.

A later project, also made on a bet, was a 12 ga. shotgun, also made with almost unaltered hardware store components.
