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 seems like that should be invalidated as a law? Like it would be if the feds pre-empted it.
But the courts have previously ruled that you can’t illegalize dual use devices that have legitimate legal uses and possible illegal ones, as they tried to do with CD burners back in the day for the record companies, may they burn in hell.
Not sure that would apply?
