Who's up for a 3D printed bridge?

Video of the day: Fully 3D Printed Rifle The Grizzly Hand Firing

Hand firing 3 more shots through the Grizzly 2.0 with the same barrel for a total of 14 shots. On the 14th shot a crack develops around the chamber. The rounds fired are Winchester Dynapoints.  

The 1st 3D printed gun is here. Gun control is now impossible.

The 1st all-plastic gun (except nail for firing pin) is now ready for download to your 3D printer. 

The (almost) all-plastic 3D-printed Liberator pistol was announced by Defense Distributed late last week, but with the gun's blueprints and construction details now live on the company's own DefCAD design site, it's also released a video taken during its testing. In front of a Forbes onlooker, the clip apparently shows a 0.380 caliber bullet being fired by the Liberator.

The only non-plastic part of the design is a common nail, which acts as the firing pin. Defense Distributed's founder Cody Wilson has worked over a year on the project, apparently citing the one-shot pistols that were designed to be air-dropped over France during World War II as inspiration -- also called the Liberator. This modern version is, however, formed of 15 components made inside a Stratasys Dimension SST 3D printer. The video of the test shot and more details are right after the break.

Amusing: New durable 3-D printable 30 bullet magazine named the “Cuomo.”

With new 3-D printing technology, gun control is being made obsolete...

Via Wired:

In response to the upsurge in gun violence, politicians are proposing restrictions on the number of bullets that handgun and rifle magazines can hold. And just as they do, new printing technology blows holes right through that debate. The 3-D printing gunsmiths at Defense Distributed are about to release blueprints for an upgraded magazine that won’t degrade even after you fire hundreds of rounds.

Meet the “Cuomo.” It’s a new printed magazine for your AR-15 rifle, soon to be available for download, and it holds 30 bullets. Upgrading an earlier design that didn’t hold up particularly well after extended use, it’s an unsubtle rejoinder to New York Governor Andrew Cuomo, who recently signed a magazine-restriction law limiting mags to seven rounds. Defense Distributed is basically saying that if you’re not going to be allowed to buy larger magazines in the near future, you can print them yourself — if, that is, 3-D printed weapons don’t fall into legislators’ own crosshairs.
