A new bill proposed in the California State Assembly could potentially require the makers of 3D printers to confirm that they are using algorithms or other technologies to prevent the printing of firearms.
The new bill is AB-2047, and it mostly mimics Washington's HB 2321 and New York Assembly's S9005/A10005, all proposed recently in 2026. However, California goes one step further by "[banning] the sale or transfer of any 3D printer in California unless it appears on a state-maintained roster of approved makes and models."
