Bill > AB2047

This bill, known as the California Firearm Printing Prevention Act, establishes a framework to regulate the sale of three-dimensional (3D) printers in the state by requiring them to include built-in "firearm blocking technology"—meaning hardware or software mechanisms designed to scan digital print files and prevent the creation of homemade firearms or machine gun conversion devices. Beginning in July 2027, the California Department of Justice will periodically check if ASTM International, an organization that develops international technical standards, has published official industry standards for this type of safety technology. If ASTM publishes these standards, the state Department of Justice must issue its own official guidance and minimum performance rules within 24 months, and one year after that, it will become illegal to sell or transfer any 3D printer in California that lacks compliant blocking technology. The bill exempts 3D printers used exclusively for making props in the entertainment industry, protects developers who test and refine blocking technology from civil liability for sharing digital firearm code, and includes a severability clause ensuring that if any part of the law is struck down by a court, the remaining parts will still remain in effect.
