Yes its happened, Philadelphia’s City Council has banned 3D printed guns to make it the first city in the United States to do so. After the unanimous vote to ban the manufacturing of guns from 3D printers, the author of the bill, Kenyatta Johnson still isn’t aware of any local 3D printer gun manufacturers. ”It’s all pre-emptive,” says Johnson’s director of legislation Steve Cobb. “It’s just based upon internet stuff out there.”

“As technology progresses, three-dimensional printers will become more advanced, less expensive and more commonplace,” Councilman Kenyatta Johnson said after the vote. “As instructions for the manufacture of guns via 3D printing technology are already available on the Internet, we could be looking at a recipe for disaster.”

While people have been manufacturing guns for centuries, recent developments such as Solid Concepts metal 3D printed gun may have been the tipping point for the Councillors. Still, it would be easier and cheaper for somebody to make a gun in a machine shop or even buy one illegally than producing them on a 3D printer.

It will be interesting to see how they enforce the bill as it will be almost impossible track the manufacturing of them. The banning of 3D printed firearms seems to be politically motivated rather than anything to do with public safety and home security.
