How about California AB 2047? - requires 3D printers sold in the state to be DOJ‑approved and equipped with firearm‑blocking technology. It also criminalizes disabling or bypassing the blocking software. Maybe another bill, but it makes all open-source for 3D printers illegal.
California AB 2607? Requires firearm‑detection/blocking modules in all 3D printers sold in the state.
Colorado HB26‑1144? Bans manufacturing firearm components via 3D printing; bans digital instructions.
Washington HB 2321? - requires 3D printers to include blocking features that cannot be bypassed even by technically skilled users. Prohibits using 3D printers/CNC to manufacture certain firearm components; restricts digital firearm manufacturing code.
Just like in the firearm community, the problem is not the objects (firearms, bullets, 3d printed parts) it is politicians who are grossly uneducated, technophobic, and ignorant.
