A new U.S. federal law aims to block the production of guns using 3D printers by leveraging the National Firearm Reference Vault. This policy affects manufacturers and individuals who use 3D printing technology to create firearms, with supporters arguing it prevents untraceable weapons while opponents raise concerns about innovation and rights.

The dispute centers on the law's scope and enforcement authority, with the National Services Center involved in implementation and the National Rifle Association opposing the measure. The law's next procedural steps remain pending.
