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.


So in other words, what else is new?
The danger if this passes isn’t that someone will be able to successfully implement some manner of system for identifying gun parts which will, apparently, rely on pixie dust and magic. In reality this will effectively prohibit 3D printer sales in California entirely because compliance is literally impossible. And it’ll and give overreaching cops and prosecutors yet another nonsense charge they can arbitrarily slap people with over “circumventing” this mystical technology which does not in fact exist if they, ye gods forbid, build their own printer.
It’s the same horseshit rationale as the spent casing “microstamping” fantasy that legislators have been salivating about for decades. It doesn’t work, it’ll never work, but that’s not going to stop them from wishing it does and therefore turning it into a defacto ban.
Keep in mind, California also has the precedent of their infamous approved handguns list, which notoriously does things like arbitrarily declaring that the black version of some model of gun is legal, but possession of the stainless version of the exact same gun is a felony. We’re not dealing with people in possession of any type of rationality, here.
I haven’t read the bill, but from the description I think you could actually get around this by building your own. They can’t sell a printer that doesn’t have this, and you can disable it, but it doesn’t say here that you can’t build your own that never had the software. In that case, I assume we’ll see kits that are totally not meant to be assembled into printers with all their parts you need, and then unrelated documentation online somewhere on how to assemble it.
It seems they are rationally putting pressure upon those willing to own guns or 3d printers.
Like most of rifle shots fired in WWI didn’t kill anyone and were meant for suppression.
Making you afraid of everything that can be a legal trap. Thus possibly dropping the thought of even owning this or that thing.
Except for the fact that this doesn’t put any pressure on anyone who wants a gun (those are still really easy to get in California, just not as easy as most other states). But those who benefit the most from this law are gun manufacturers, and not long after when this bill is extended to printing replacement parts for anything, all companies that charge inflated prices for repair parts or design their products to be unrepairable entirely.
What people who print “guns” are actually printing is gun furniture. Custom grips and the like, either for comfort/aesthetics or so they can take cheaper gun parts and use them to build a clone of a similar gun from a company that charges more. They still use legally purchased gun internals.
The gun that Luigi Mangione supposedly used was a Glock, legally purchased and one of the most ubiquitous pistols in the world, with a 3d printed grip on it. Every other part of that gun came from the manufacturer.
The gun used to kill Shinzo Abe, however, was made entirely out of simple materials readily available at any hardware store and is completely legal in all 50 states. Because a gun like that is considered a “garage gun” and those are legal under federal law because it’s essentially impossible to stop somebody from gluing together a pipe and a nail to strike the bullet with and fire it down the pipe barrel. But 3d printed gun parts don’t fall under the same regulations and those who stand to lose the most from people 3d printing are those who charge unreasonable prices.
You know who else would benefit from this law? Games Workshop, who sells many miniature figures for $40+ each, and a few for over one thousand dollars.
I live in Russia and here this is very illegal. It can suddenly become where you live too.
I was just talking with a friend about the microstamping idea. I’d never heard of it before.
