California’s bill, AB 2047, will not only mandate censorware on all 3D printers; it will also criminalize the use of open-source alternatives. Repeating the mistakes of DRM won’t make anyone safer, but it will hurt innovation in the state and risks a slew of new consumer harms ranging from surveillance to platform lock-in. California must stand with creators and reject this legislation before it’s too late.

The California legislature may pass a bill that will require censorware on all 3D printers, and would make it a misdemeanor for the owner of a 3D printer to disable, deactivate, or otherwise circumvent that algorithm. This effectively criminalizes the use of any third-party, open-source 3D printer firmware.
