A Working Assault Rifle Made With a 3-D PrinterBy John RobbPosted 07.26.2012 at 5:29 pm

HaveBlue then decided to push the limits of what was possible and use his printer to make an AR-15 rifle. To do this, he downloaded plans for an AR-15 in the Solidworks file format from a site called CNCGunsmith.com. After some small modifications to the design, he fed about $30 of ABS plastic feedstock into his late-model Stratasys printer. The result was a functional AR-15 rifle. Early testing shows that it works, although it still has some minor feed and extraction problems to be worked out.

People are doing cool stuff printing tools and all. But I don't think I'd want to put a printed weapon next to my face and fire it.

I watched a news segment a while back on 3D printer technology and it's really insane to think of the possibilities it holds. Someday we could all have our own replicators in our houses like Star Trek. It could also make various manufacturing sectors obsolete. No need to head to Wally to buy cheap Chinese toys for the kids when you can make your own in the basement. :lol:

Never thought about guns though, kind of scary when you start thinking of the bad things you could make.

Media falsely reports man used 3-D printer to make assault rifle

 
But the only part of the gun -- an AR-15 -- that was fabricated using the 3-D printer was a part that did not have to withstand the explosions of the cartridge going off, nor was it a part that hasn't been made of plastic in other guns already. The chamber was not fabricated, the barrel was not fabricated, the bolt wasn’t, and the firing pin wasn't. In fact, none of the most important working parts were created using the 3-D printer.

Okay, but except for the chamber, the barrel, the bolt, and the firing pin the AR-15 was printed. Are those parts important? :lol:

 
kind of related...but good little video from an engineering professor suggesting 3D printers can be used to build structures such as homes.

http://news.yahoo.com/blogs/sideshow/3d-printer-could-build-house-20-hours-224156687.html

In the video, the professor demonstrates how the machine lays down a concrete foundation, puts up walls, even inserts wiring and plumbing, and eventually constructs an entire building, which Professor Khoshnevis says can be completed in less than a day.
