California’s New Bill Requires DOJ-Approved 3D Printers That Report on Themselves (blog.adafruit.com)

California’s new bill requires DOJ-approved 3D printers that report on themselves targeting general-purpose machines.

Assembly Member Bauer-Kahan introduced AB-2047, the “California Firearm Printing Prevention Act,” on February 17th. The bill would ban the sale or transfer of any 3D printer in California unless it appears on a state-maintained roster of approved makes and models… certified by the Department of Justice as equipped with “firearm blocking technology.” Manufacturers would need to submit attestations for every make and model. The DOJ would publish a list. If your printer isn’t on the list by March 1, 2029, it can’t be sold. In addition, knowingly disabling or circumventing the blocking software is a misdemeanor.

It's not about firearms.

It's about controlling what you can 3D print.

When your 3D printer has to connect to a third party service to check if it's allowed to print what you just sent it. That's a clear vector for companies to enforce IPs.

Printing a replacement part for your appliance? Sorry, they're blocked.

Printing parts to repair part of your vehicle or snap something back on? Sorry, that's banned.

Printing something that resembles the intellectual property of any other company? Sorry, that's banned.

Can't have you cutting into the profits of corporations by self-servicing and self-repairing.

Also a mass surveillance device to produce surveillance of what people are 3D printing and report it to a central authority.

Ok however its hard for me to believe that such measures could render effective. Regulating the tech literate people in such a way will always fail. The only effect it could have is that when its illegal to posses a unregistered/hacked you are an easier target for "law enforcement actions"
