California's proposed legislation would require 3D printers to detect and block the manufacture of untraceable firearms, a move the Electronic Frontier Foundation warns could expand government surveillance of consumer devices.

The bill seeks to embed detection technology into 3D printers to prevent production of so-called ghost guns—firearms without serial numbers manufactured at home. Under the proposal, manufacturers would need to implement software that identifies firearm components and prevents printing. The EFF argues the measure creates troubling precedent by deputizing consumer hardware to enforce law. The organization warns that mandating detection systems in 3D printers could lead to similar requirements for other devices and represents a form of automated censorship built into products. Ghost guns have become a focal point for California lawmakers concerned about untraceable weapons. The state previously banned the sale of 3D printer files for firearms and unfinished receiver blanks. Proponents say the technology requirement targets a specific problem. Critics counter that detection systems are unreliable, could be circumvented, and shift policing responsibility to manufacturers rather than law enforcement.
