Under the proposal, printers would have to evaluate STL files, CAD files, or other geometric code using a firearm blueprint detection algorithm and block files flagged as capable of producing a firearm or illegal firearm parts, including conversion devices.

California’s Department of Justice, or another relevant state agency, would have until January 1, 2028, to publish performance standards for detection algorithms and software control processes.

This is the problem when lawmakers write technical bills without speaking to technical people. They’re going to publish standards for evaluating if your gcode is a firearm or firearm part? THAT’S FUCKING IMPOSSIBLE
