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!)

I bought a 50-pack of plastic centrifuge tubes for $14 on Amazon a couple of years ago. I was planning to use them to do geocaching with my daughter but we both lost interest. I left the tubes in a bag in the garage. A couple of weeks ago I needed a screw to fix […]
Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
