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.

Thanks, yeah, my friends use Fusion 360. I don't have a working Windows machine right now but maybe I can set something up or run under Wine.

Yeah right now what I want to do is duplicate a shower door guide which is a 3 inch plastic part with some specific grooves and a screw hole. It's incredibly hard to find the right one online or tell that it's right. Home Depot doesn't even have that kind of thing in their store any more. I do at least have a reasonably intact one that I can measure with a caliper.

Yikes, a 28 minute video, but I guess I'll watch it during some downtime at some point. Thanks again.
