Hawaii already restricts 3D-printed firearms under HRS section 134-10.2. The statute makes it illegal for anyone not licensed as a manufacturer or dealer to purchase, produce with a three-dimensional printer, or otherwise obtain an unserialised firearm receiver or combination of parts for the purpose of assembling a firearm.
HB 392 would have gone further, defining ghost guns to include anything made by 3D printing or self-assembly without a registered serial number, making possession, transfer, manufacture and sale a Class C felony, and adding mandatory minimum sentences. It was introduced in 2025, carried over into 2026, missed its committee deadlines, and died when the legislature adjourned on May 8, 2026.
HRS 134-10.2 (active): unlicensed persons may not produce an unserialised firearm receiver or parts combination with a 3D printer for the purpose of assembling a firearm.
On firearms assembled from 3D-printed parts, the serial number must be engraved on stainless steel and permanently embedded into the receiver during fabrication.
When registering a firearm made by additive manufacturing, the police registration database must log "3-D printer" in the manufacturer and model field.
HB 392 (died in committee, May 2026): would have made possession, transfer, manufacture or sale of a 3D-printed or unserialised firearm a Class C felony with mandatory minimum sentencing.
