Yesterday, I wrote about Defense Distributed's 3D printed handgun, and asked whether it would fire, and how many rounds it could fire before experiencing stress fractures, melting, etc. Now, Forbes's Andy Greenberg follows up with a report of the successful firing of the gun -- though not its longevity -- and says that Defense Distributed will publish the CAD files for printing your own gun on its site today, along with videos of the gun in action.
Unlike the original, steel Liberator, though, Wilson’s weapon is almost entirely plastic: Fifteen of its 16 pieces have been created inside an $8,000 second-hand Stratasys Dimension SST 3D printer, a machine that lays down threads of melted polymer that add up to precisely-shaped solid objects just as easily as a traditional printer lays ink on a page. The only non-printed piece is a common hardware store nail used as its firing pin...
Even Wilson himself says he’s not sure exactly how that’s possible. But one important trick may be the group’s added step of treating the gun’s barrel in a jar of acetone vaporized with a pan of water and a camp stove, a process that chemically melts its surface slightly and smooths the bore to avoid friction. The Dimension printer Defense Distributed used also keeps its print chamber heated to 167 degrees Fahrenheit, a method patented by Stratasys that improves the parts’ resiliency.

Mondo Tees has announced a line of Aliens xenomorph tiki mugs, (“in space, no one can hear you drink”), available for pre-order now with ship dates this summer (some glazes only available at Alamo Drafthouses).
The Signal Sidearm is a sensor designed to be fitted to a police pistol holster: when triggered, it wirelessly signals all nearby police bodycams to go into record-and-archive mode. It’s made by Axon, the bodycam division of Taser International.
Spiral Toys — a division of Mready, a Romanian electronics company that lost more than 99% of its market-cap in 2015 — makes a line of toys called “Cloudpets,” that use an app to allow parents and children to exchange voice-messages with one another. They exposed a database of millions of these messages, along with […]
Wireless headphones aren’t a mind-bending thing anymore now that Apple made them the standard thing-to-be-outraged-over-in-the-new-iPhone fare, thereby killing the cool factor. But let’s be reasonable here. Wires really are a pain when you’re running, trying to get off the bus, or even just standing up from your desk. Wireless headphones make sense, they just don’t […]
Python is such a commonly used general-purpose programming language and features such (comparatively) simple syntax, that most veteran programmers consider it an excellent foundation for aspiring programmers. The Python 3 Bootcamp Bundle packs over 30 hours of training into nine courses to build that foundation for you.If you’ve never had any introduction to code at […]
