Bill > AB2047

This bill, the California Firearm Printing Prevention Act, aims to prevent the unlawful manufacturing of firearms using 3D printers by requiring manufacturers to implement "firearm blocking technology" in their devices. This technology includes a "firearm blueprint detection algorithm," which is software designed to identify and prevent the printing of files that could be used to create firearms or illegal firearm parts. By September 1, 2028, the Department of Justice (DOJ) will publish performance standards for these algorithms and related software controls. Manufacturers must then submit attestations to the DOJ by March 1, 2029, confirming their 3D printers are equipped with this technology, and the DOJ will maintain a public list of compliant printers. Beginning December 1, 2029, it will be illegal to sell or transfer 3D printers in California that are not equipped with this blocking technology and are not on the DOJ's approved list, with certain exceptions for specific industries and law enforcement. The bill also makes it a crime to knowingly disable this technology with the intent to manufacture firearms, and allows for civil actions against those who sell non-compliant printers.
