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.

I can see you care about this topic. I'm not here to piss in your soup. I just said what the purpose is.

But in essence you are correct. The problem isn't that you can print certain parts, it's how easy it is to access everyone else supporting it. E.g. bullets or shells

Don't worry, you're not pissing in my Cheerios or anything, I just always end up in one of those "That's not how this works. That's not how any of this works!" rants whenever they pull the "ghost gun" nonsense.

It's like how it's illegal in Mass to own a suppressor unless you're a cop or military, then you can buy as many as you want. Like...it reduces recoil a little and reduces the noise from permanent hearing loss to temporary hearing damage, it's not gonna make a gun silent. Movie magic quiet is only possible with very particular sub-sonic rounds of a specific caliber. You want silent? You put a suppressor on an air rifle. Dead silent and completely legal to put a suppressor on in all 50 states because it's not a gun, despite being just as dangerous at close ranges.

Edit: Also, these laws are often supported by firearms manufacturers because it benefits them to prevent people from being able to go elsewhere, like making aftermarket car parts illegal or forcing people to get their service done at a car dealership.
