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.

A flashlight review that begins with the promise “I’m about to hike through a remote canyon to an abandoned mine, and I gotta tell you there’s a storm raging outside” should end on an interesting note, and this one does. [via] Disturbing, strange sounds. That’s exactly what I caught on video while filming and documenting […]
Reflectacles, the hyper-reflective Ray Ban-style $75 glasses frames that Scott Urban is Kickstarting have a new feature: now you can get ones doped with materials that reflect the infrared light that CCTVs kick out to let them capture images in low light, which blind cameras’ sensors. Cool!
Typewriter historian Martin Howard (previously) writes, “I was able to pick up a rare and exquisite Waverley typewriter (1896) this summer in Scotland and have just the other day posted it to my website all cleaned and ready to show.”
Loot Crate is a totally different kind of subscription service that mails subscribers monthly boxes filled with curated geek, pop culture, and gamer paraphernalia. Its cult following awaits a box every month filled with everything from bobble heads to T-shirts to special edition collectibles. But nothing gets Loot Crate fans as excited as the limited […]
The ARMOR-X Mini Flexible Phone Tripod is a smartphone tripod that is designed with flexible legs to rest on virtually any type of surface. Other tripods have proved useless unless I conveniently have a flat surface in front of me, which is why this particular tripod was appealing enough to try out. The ARMOR-X is compact and easy […]
You don’t need to get an advanced degree and take out massive loans to become a coder. This bundle of 10 courses was designed to teach anyone to code at home for less than it costs to go out for dinner. I was particularly impressed with this new 2017 bundle because it includes courses on […]
