I don't know what language you speak but here is a part of the bill in English

This bill would require, on or before July 1, 2028, any business that produces or manufactures 3-dimensional printers for sale or transfer in California to submit to the department an attestation for each make and model of printer they intend to make available for sale or transfer in California, confirming, among other things, that the manufacturer has equipped that make and model with a certified firearm blueprint detection algorithm. If the department verifies a printer make and model is properly equipped, the bill would require the department to issue a notice of compliance, as specified. The bill would require, on or before September 1, 2028, the department to publish a list of all the makes and models of 3-dimensional printers whose manufacturers have submitted complete self-attestations and would require the department to update the list no less frequently than on a quarterly basis and to make the list available on the department’s internet website. The bill, beginning on March 1, 2029, would prohibit the sale or transfer of 3-dimensional printers that are not equipped with firearm blocking technology and that are not listed on the department’s list of manufacturers with a certificate of compliance verification, except as specified. The bill would authorize a civil action to be brought against a person who sells, offers to sell, or transfers a printer without the firearm blocking technology.

Let me point out the statement:

> The bill, beginning on March 1, 2029, would prohibit the sale or transfer of 3-dimensional printers that are not equipped with firearm blocking technology and that are not listed on the department’s list of manufacturers with a certificate of compliance verification, except as specified.

It seems pretty clear this would prohibit the sale of 3D printers that are not approved by the California DoJ.

It's not nice to lie about extremely obvious things.

Clearly this is mostly security theatre (see eg comment about proving that them printer can't print a printer that can print a gun).

On the other hand - it would be low hanging fruit to prevent off the shelf printers to print well known gun parts? Much like photocopiers and scanners and printers won't scan, copy or print known currency bills?

Actual text from your link is:

> (a) Any business that produces or manufactures three-dimensional printers for sale or transfer in California shall take both of the following steps

This is worded a bit ambiguously: it's not clear whether it's meant to be "manufactures ... in California" or "for sale or transfer in California". IANAL, but wouldn't the latter be unconstitutional inasmuch as it conflicts with federal jurisdiction over interstate commerce? It seems unlikely that California would be able to enforce this against businesses that have no operational presence there, and are merely shipping 3D printers to California from other states.

And if that's the case, the only meaningful effect of this bill passing will be to further motivate anyone making or selling 3D printers to leave California for other states.

> It seems pretty clear this would prohibit the sale of 3D printers that are not approved by the California DoJ.

Note the difference w.r.t. the ridiculous "California's New Bill Requires DOJ-Approved 3D Printers".
