Bill > AB2047

This bill requires the California Department of Justice (DOJ) to develop and implement a system to prevent the 3D printing of firearms by mandating that 3D printers sold or transferred in California be equipped with "firearm blocking technology," which includes a "firearm blueprint detection algorithm" (software that identifies and blocks designs for firearms or illegal firearm parts) and "software controls processes" (measures to ensure the algorithm functions properly). The DOJ must establish performance standards for these technologies by January 1, 2028, and by July 1, 2028, manufacturers must submit attestations confirming their printers meet these standards. Starting March 1, 2029, only 3D printers listed by the DOJ as compliant can be sold, and it will be illegal to disable this blocking technology with the intent to manufacture firearms, with violations potentially leading to civil action or misdemeanor charges.
