Submission + - The ATF Isn't Convinced That 3D-Printed Guns Compare to the Real Thing (vice.com)
"We are aware of all the 3D printing of firearms and have been tracking it for quite a while," Earl Woodham, spokesperson for the ATF field office in Charlotte, said. "Our firearms technology people have looked at it, and we have not yet seen a consistently reliable firearm made with 3D printing."
A reporter called the ATF's Washington headquarters to get a better idea of what it took to make a gun "consistently reliable," and program manager George Semonick said the guns should be "made to last years or generations." In other words, because 3D-printed guns aren't yet as durable as their metal counterparts, the ATF doesn't yet consider them as much of a concern.
