An entirely 3D printed firearm.

So basically a paper cartridge muzzle loader with electric igniter instead of percussion caps? I mean, I’m all in on black powder goodness, but this is a little different. Wonder about the barrel. Is it really all plastic? Then how many shots can it take before the barrel gives up? Read a few comments talking about pressure differences between black powder and smokeless, but still a little concerning.

Of course, like the WWII victory gun, all you need to get a better gun is a one shot throw-away.

    There is equipment that will 3D print with metal. Not sure I would trust it as a firearm for long term use, but it’s better than throwing a rock.

      Way back in the 80’s, my college project in engineering was coating metal particles with polymer so it could be 3D printed like you said. We didn’t call it that back then, but the idea was you’d print the polymer coated metal, the polymer would cause it to stick together in it’s desired shape. You’d then put it in an (easy-bake – LOL) oven and reach temps at which polymer would burn away and the metal would sinter and fuse. We didn’t get much beyond proving the concept, but I’m aware of the concept.

      If I just needed a single shot “better than throwing a rock” gun, I’d be more inclined to go with a length of pipe, a cannister of high pressure air, and a 50 cal pellet. A little bulky, but if it gets me to a better gun then it served a purpose. Thankfully I lost all my guns in a canoe accident. If I need a gun, it’s as simple as renting some scuba gear 🙂

A plastic .50 cal?
Oh, wait, black powder .50, not BMG.

I wouldn’t want to be the guy writing this guy’s accidental death & dismemberment policy in any event.

Call back when this guy can get through two magazines consecutively, and still has all his body parts intact afterwards.

Before then this is a curiosity, not a weapon.

Oh, wait again,…magazine?
Or has he just invented a plastic Brown Bess?

I need an eye roll emoji.
