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.

I’d call it a spoiler, but you already know what’s coming: “As Seen On TV” garden gadgets are not much good, however ingenious they seem to be. Household Hacker picked up a few items and subjected them to tests. None were terrible or dangerous, but the gimmicks don’t really work — a trimmer that uses […]
The Inverter is a kickstarted, sub-$500, 34mm automatic mechanical watch built around Citizen's Miyota Calibre 9000 movement, augmented with a custom module that makes the watch run backwards, so that it can be mounted so that the movement is exposed (beneath a sapphire crystal), with the back of the watch becoming its "face."
Damon Beres notes that the situation with folding displays is quickly going to hell. Enter Samsung’s Galaxy Fold, a kind of metal and glass taco that could define a new category of personal device — provided the company can get the thing to work. Several tech writers accidentally broke the gadget’s foldable display shortly after receiving review […]
