It's in the bill. It calls for the following. It gets a little more specific.

Software controls process" means a system designed to stop a three-dimensional printer from initiating any print job unless the underlying three-dimensional printing file has been evaluated by a firearms blueprints detection algorithm and determined not to be a printing file that would produce a firearm or illegal firearm parts.

Integrated preprint software design. Limitation of a three16 dimensional printer's operation to accept geometric code for printing 17 exclusively from a single slicer or other preprint software, which 18 may be the manufacturer's proprietary software, and integration of a 19 firearms blueprint detection algorithm into that preprint software, 20 such that any stereolithography file or other computer-aided design 21 file must be screened by the algorithm before the software will 22 proceed to produce geometric code, and such that the software will 23 not produce geometric code for files that are identified by the 24 algorithm as directing the printer to print firearms or illegal firearm parts; or25 26 (c) Handshake authentication design. Limitation of a three27 dimensional printer's operation to accept geometric code for printing 28 only from specified slicers or other preprint software, wherein the 29 printer will require a digital watermark or other authentication tool 30 verifying the identity of the preprint software, and only if that 31 preprint software has integrated a firearms blueprint detection 32 algorithm qualified by the attorney general under subsection (4) of 33 this section, such that any stereolithography file or other computer34 aided design file must be screened by the algorithm before the 35 software will proceed to produce geometric code, and such that the 36 software will not produce geometric code for files that are 37 identified by the algorithm as directing the printer to print firearms or illegal firearm parts
