The national panic over Defense Distributed is overblown, Medium blogger BJ Campbell argues:

For one, it’s already legal to assemble your own gun for personal use under government rules, as long as you don’t have a felony or domestic violence charge, Campbell writes.

It’s also much cheaper to buy a gun than a 3D printer, and even criminals who can’t pass a background check would have little difficulty buying what they need on the black market, according to a Frontline investigation.

The upper range for the number of 3D printers in the U.S. is believed to be around 300,000 by at least one trade publication’s estimate, Campbell adds. In the unlikely scenario that all 300,000 owners decided to print a gun, it would be an increase in guns per capita of just 0.086%.
