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.

my current printer is powered by an arduino mega, and it's staying that way while i can. the best appliances are the ones you can control and replace yourself if you need to. 😉

all parts you can find at a hardware store + some 3d printed pieces. repraps and foss printers are the best period.

I am the owner of a brand new Prusa MK4S. A lot of its components aren't open source, but it's an i3, I can keep it running, and I can hit its wifi module with a hammer if I want to.
