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.
Applicability is in the eye of the beholder… of bureaucracy.
It is not really enforceable what people grow in their nook with led lights, or what they produce with metal lathes and metalworking tools, or what they mix up with common chemicals, and yet!
With EURion, printers/scanners that are capable of somewhat convincing replica go into the “definitely need to do this thing” money bracket I guess.
Printer instructions are also usually quite convoluted (don’t event know if anybody really knows the actual format), but definitely it’s not the actual document being sent to a printer (except some last decade printers perhaps), just the actual dithered inkjet patterns, though I am heavily guesstimating. And yet, from inkjet patterns, the printer knows to crash, presumably, though I dont know, the knowledge of currency steganography seems spotty…
There is a semi-infinite amount of processing that can be done on the slicing machine, so detecting gun-like item is wildly possible. Making your own slicer is the same as making your own photoshop (or hacking it). I definitely don’t see 3d printers having enough horses to figure out a non-watermarked-model produced geocode to have gunlike things. But! We forget! With legislation, everything is possible. Probably will require any decent (especially things like metal) 3d printer to have an ISIC specifically programmed to rebuild a model from geocode and do analysis :D (Honestly, completely easy with current technology, MNIST 99.99% accuracy fits into 10k transistors or so)
But I guess this assumes same amount of know-how and confident skills that they had in 90s. It will probably all crash and burn and make all honest customers very unhappy.
