AB 2047

Existing law makes it a crime to knowingly or willfully cause another person to engage in the unlawful manufacture of firearms or knowingly or willfully aiding, abetting, prompting, or facilitating the unlawful manufacture of firearms, including the manufacture of assault weapons or .50 BMG rifles or the manufacture of any firearm using a 3-dimensional printer, as specified. This bill would require, on or before September 1, 2028, the department to publish written guidance on performance standards for firearm blueprint detection algorithm for use by 3-dimensional printer manufacturers, as specified. This bill would require, on or before March 1, 2029, 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 firearm blueprint detection algorithm. The bill would require, on or before June 1, 2029, 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 December 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, 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. This bill would also make it a crime to knowingly disable, deactivate, uninstall, or otherwise circumvent any firearm blocking technology installed in a 3-dimensional printer with intent to manufacture firearms or to knowingly distribute, sell, or transfer for consideration in California one or more modified versions of a 3-dimensional printer identified on the Department of Justice’s list of 3-dimensional printers eligible for sale in California, with the intent to facilitate the unlawful manufacture of firearms. By creating a new crime, this bill would impose a state-mandated local program. This bill would make these provisions severable. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
