3D Printed Gun Safety Act of 2023

This bill prohibits the online distribution of digital instructions (like 3D printer files) that can automatically create firearms or complete firearm frames/receivers. It directly affects individuals or entities sharing such code online, not those using 3D printers to make guns. The key mechanism bans sharing this code via the internet or World Wide Web, aiming to prevent untraceable firearms that lack serial numbers. This addresses a safety concern where 3D-printed guns evade detection and background checks, undermining firearm tracing used in crime investigations.
