Direction

Firearms weapon accessory restrictionsAI label

Restricts gun access model confidence 90%

Requires 3D printers sold in California to include firearm blocking technology that prevents printing of firearms or machine gun conversion devices once standards are set, so fewer 3D-printed guns can be made.

It shall be unlawful to sell, offer for sale, or transfer for consideration a three-dimensional printer in the State of California that is not equipped with firearm blocking technology that meets the minimum performance standards set forth in the department’s guidance or regulations.

Why the model tagged it this way: The bill primarily restricts by mandating firearm blocking technology on 3D printers sold in CA to block printing of firearms and conversion devices (with standards to be set by DOJ based on ASTM), and prohibits sales of non-equipped printers. It also expands by creating a new exemption from existing civil liability for distributing digital firearm manufacturing code when used solely for developing or testing such blocking technology. No other topics are substantively addressed.
