Defense Distributed, a group that is developing free designs for weapons made on 3D printers, tested out a firearm that has a plastic lower receiver made on a 3D printer. It successfully fired six rounds before splitting.
HaveBlue claimed in July to have fired his printed gun hundreds of times, which doesn't seem impossible given the quality of the printing. The part printed by the group is called the lower receiver, which is where a round is received from the magazine. Pictures show it to be very well made, and it appears to fit exactly to the other parts in the gun kit they used.
But the pressure of the recoil appears to have been too much for the "buffer ring," which separates the stock from the upper receiver. After firing just six shots, the gun split in two. It's a serious setback, especially considering they were firing a lower-caliber cartridge than the gun would normally shoot.
3D printed gun fires 6 shots - then falls apart (Thanks, Lew!)

Just look at it. (Thanks, Geoff Cole)
Nicole Prause is a sex researcher who wanted to design a gender-neutral orgasm-measuring tool that would fit in the anus and detect and measure pelvic contractions but all the buttplugs she tried to modify ("We ordered like 20 of these butt plugs off Amazon, and it messed up my recommendation engine for all time") were […]
CNC Kitchen's 18-minute video on nozzle wear in 3D printing involves sending abrasive filaments (the abrasiveness comes from pigments and additives like carbon fiber, etc) through a variety of nozzles (mostly cheap ones from China), then measuring the results with a micrometer and by taking castings of their interiors -- but the best part is […]

On the one hand, nostalgia is “a corruption of the historical impulse,” according to William Gibson. On the other hand, “Super Mario Bros.” will never not be cool. Luckily, there’s a way to satisfy that retro gaming while still keeping an eye on the future: The GameShell Kit. This thing is simultaneously the last handheld […]
The field of data analytics can get intimidating, even for business professionals who constantly rely on it. But at its heart, its purpose is to simplify. To take mounds of information and distill their insights into a single clear picture. Currently, the go-to software for painting that picture is Tableau. And if you want to […]
