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.
Silly woman who proposed that bill, if passed the law will only create a black market for 3D printers.
And largely unenforceable. Like, it can only really block the sale of prebuilt, proprietary crap like Bamboo, but most of these things are built out of common parts that are used for a verity of applications and there are countless completely open source printers you can just built from sourced parts that this literally cannot apply to.
Even for most of the prebuilt or kits you get you put open source firmware on it. They can boot lock the board that comes with it, technically, but the board is easy enough to replace on most printers and it's a standard micro controller and/or raspberry pi nowadays.
Half the time people who get those kits end up replacing various components to customize for their use case. I have a Sovol SV08 that I put stock Klipper on and want to do the multi-print-head mod someday. I've even considered replacing the main board with a more powerful one so I can run higher microsteps without overloading the processor.
