The Liberator, the first completely 3D-printed gun, gets test-fired (video)

The Liberator, the world's first completely 3Dprinted hand gun, gets fired video

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 .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.

$17,000 Rifle Uses Linux Wizardry And Fancy Scopes To “Auto-Aim”

Let’s get the moral aspect out of the way first: we’re not big fans of killing for sport. We’re not going to turn this into a debate on the topic, but we’re only covering the TrackingPoint XS1 because, frankly, that’s some impressive tech. What is it? It’s a rifle that takes so much guesswork out of aiming, a child could do it. Not that a child should, but we’re just sayin’. The company calls it a PGF, a precision guided firearm. And this is how it works:

To shoot at something, you first “mark” it using a button near the trigger. Marking a target illuminates it with the tracking scope’s built-in laser, and the target gains a pip in the scope’s display. When a target is marked, the tracking scope takes into account the range of the target, the ambient temperature and humidity, the age of the barrel, and a whole boatload of other parameters. It quickly reorients the display so the crosshairs in the center accurately show where the round will go.

The shooting mechanism is also different than a regular gun. Once you’ve pulled the trigger, the shot won’t go off until you line up the reticle with the previously set pip; at the precise moment they’re lined up, the bullet leaves. This eliminates a lot of the shakes associated with pulling the trigger and dramatically increases accuracy. But you can also change your mind and take the finger off the trigger altogether, and cancel your shot.
