3D-printed “ghost guns,” made of a plastic-like material, can slip through metal detectors. They’re also guns you can print for yourself at home.
The Justice Department is going to allow the sale of files which tell a 3D printer how to create a gun. 3D printers create objects by spraying material, layer by layer from the bottom up.
“In order to print really anything you have to either have a file or create a file,” says Matt Cushman, co-owner of Think A Little Bigger, a local St. Louis area 3D printing company.
He says these template files have already been out there on the dark web, and interest is growing.
