ExtremeTech: Global Threat of 3D-Printed Guns

A US court has put a temporary hold on a US company’s plans to publish online instructions for 3D printing of guns. Writing for ExtremeTech, David Cardinal points out that hobbyists already have many ways to make do-it-yourself guns without serial numbers or registration, and a cottage industry has developed around kits and components. “Since it’s also currently legal to sell all the pieces needed, it means that there is currently a legal way for guns to proliferate despite various state and local efforts to curb the sale of weapons,” Cardinal writes. Two concerns: Plastic 3D-printed weapons could evade metal detectors, and guns produced by the typical 3D printer would be flimsy, more dangerous for users than targets. The technology will advance though, and online gun designs have global implications. “Looking at the worldwide situation, countries that have worked hardest to reduce the number of guns are at the most risk from DIY guns of any kind,” Cardinal writes. Australia already has a law prohibiting possession of plans. He notes that regulation could extend to technology: “In particular, the 3D printing industry is nervous about potential backlash and regulation that will impact the broad adoption of what is clearly an important emerging technology.” – YaleGlobal
