California’s New Bill Requires DOJ-Approved 3D Printers That Report on Themselves (blog.adafruit.com)

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.

This is coordinated. Multiple states at the same time.

I don’t think it has anything to do with guns. Middle of the bell curve, most people aren’t using these for guns. They’re using these for right to repair. They’re using these for garage businesses. Shop businesses. Small businesses. (See: not corporate USA). Or for making/creatimg.

I’ve no doubt there are people sitting on some small slice of a tail on the bell curve who do print gun parts, but this is about corporate America.

It’s also a foot in the door dig on free and open source software.

It’s a way to block individual and small business from horning in on corporate America’s profit for a comparably tiny slice of their own.

Printing a knob to replace a broken on/off switch instead of buying a whole new item? Worse, selling that item or even just posting the pattern for free? We can’t have that.

Now, you’re bypassing my item’s proprietary system by printing…

Wait. I was able to sell threaded hand screw knobs for $5 each. Now you’re all just printing them? And the pattern is up there for free?

We need a law.

It is nothing less than, I say without exaggeration, a war on property rights as a whole.

Great points, I think you're on to something.
I think the old saying "Never attribute to malice that which can be adequately explained by stupidity" doesn't apply when malice and corporate interests are in alignment. Now I'm curious to dig into who actually wrote the bill, and who are they financially supported by...
