New bullet for 3D guns invented by PA machinist

I've been looking at the 3D printing thing for a while now with some interest. This might make them a much more practical idea down the line. Obviously, the simplicity of his idea is key. I wonder if Mr. Crumling is a PAFOAer?

I've often told anti-gun friends about alternate methods for obtaining a gun if they outlaw them & one of the many reasons bans won't work - that people can build a zip gun from junk at the hardware store. Of course, there's the cool homemade pistols from Latin America I've seen posted here, but the 3D printer really has the potential to give everyone the opportunity to arm themselves from the comfort of their home.

When they tell us that we're not allowed, Americans ALWAYS find a way to do it anyway....

star systems are like tadpoles, slippery little buggers.

looks like the shell will hit you in the eye

Would this be considered a blowback action?

The British gov't went wild when the first plans for 3-D printed guns were posted. They are terrified that the average person will make guns, staging a police raid on a computer shop for allegedly making gun parts (they were actually printing printer parts), and putting out videos showing how unsafe 3-D printer made guns were. Of course the videos were pure propaganda: they substituted 9mm for the original .22 of the original design with predictable results... A lot of governments fear losing their monopoly on power.

Once 3-D printers get cheaper and the media used for printing get better, things ought to get really interesting!

If that was the only weapon American citizens could have I think we would be better off with machetes and Molotov cocktails.

Maybe a bow staff like donatello

Totally awesome, from a fellow chipmaker.....

but you could just as easily go to your LGS and get a Jiminez for $100.
3D printing needs more time, but its small steps that get you there. Imagine a time when the percussion cap was revolutionary. !

Pretty cool solution I must say.

“It’s a really simple concept: It’s kind of a barrel integrated into the shell, so to speak,” 25-year-old Michael Crumling said. “Basically it removes all the stresses and pressures from the 3D-printed parts. You should be able to fire an unlimited number of shots through the gun without replacing any parts other than the shell.”

The ammunition has a thicker steel shell that contains a lead bullet an inch inside. That allows the shell to be able to handle the explosion from the gun as it’s fired without affecting other parts of the gun.

But the gunsmith’s new .314 Atlas ammunition does have its limitations.

For example, it can take up to an hour to make. However, Crumling pointed out that once the rounds have been made and shot they can be ready to shoot again as soon as they’re repacked with gunpowder, bullets and primer.

That seems easy enough. But perhaps not so easy has been all the legal precautions Crumling has had to take to ensure what he’s doing is actually legal.

His test gun contains a piece of metal which makes it legal under the Undetectable Firearms Act. He’s also included a rifled bore to make sure his invention complies with the National Firearms Act. And while it’s perfectly legal to manufacture your own firearms in the U.S. without a Federal Firearms License, it’s illegal to sell firearms without a license.

That’s why, for now, Crumling is simply sharing how to design the ammunition on his website.

Despite all the legal hurdles, Crumling called his invention a “building block for the future of 3D-printed firearms.” The small rounds, he added, could later allow people to develop their own semiautomatic, and even fully automatic guns.

Neat, nice to know PA still has good inventors.
Quoted parts are from the Blaze. His Website has more pics.
Now all I need is a metal lathe and a 3D printer.

Nice 380 ACP carbine in another of his pages.

I'd go for 10mm Norma myself, using a short recoil action.
