Bill > HB2321

This bill requires that, starting July 1, 2027, any three-dimensional (3D) printer manufactured, wholesaled, or sold in Washington state must be equipped with "blocking features." These features involve a "software controls process" that uses a "firearms blueprint detection algorithm" to identify and prevent the printing of firearms or illegal firearm parts, defined as unfinished frames or receivers or parts for converting a weapon into a machine gun. The algorithm must be highly reliable in detecting these blueprints, which are digital design files (like STL files) used to program 3D printers, and the blocking features cannot be easily bypassed by technically skilled users. Manufacturers must attest to the Attorney General, under penalty of perjury, that their printers meet these standards, and the Attorney General will establish specific rules and standards for these blocking technologies. This requirement does not apply to 3D printers sold to entities with a federal firearms manufacturing license. Violations of this bill can result in misdemeanor or felony charges for individuals and a class C felony for corporations, with penalties including imprisonment and fines, and filing a false attestation is considered perjury. The bill also establishes that violations are considered unfair or deceptive acts under the Consumer Protection Act. The Attorney General is tasked with creating and maintaining a database of firearm blueprint files to aid the detection algorithms.
