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.
Even if it was in good faith: 3D printed guns are not a problem. Even if you made one it is going to jam up very quickly due to softening and melting, if not just explode all together.
It would be easier, faster, and more effective to build a gun from things sourced at the local hardware store.
Even then, If someone is going to commit a crime with a gun they are unlikely to build it themselves. Most guns used in crimes are actually legally purchased, purchased at a gunshow, or purchased on the black market.
Anyone 3D printing a gun is doing it as a novelty. Because of that I don’t see this as a second amendment violation. This is blantantly a first and fourth violation.
