Washington's 3D-Printed Gun Ban: A Blueprint for Legal Firearm Controls?

Washington State is drafting a law that would criminalize the sale of 3D printers without built-in gun-printing safeguards—turning printers into potential accomplices in a regulatory arms race.

The proposed HB 2321 requires 3D printers to include "blocking features" that detect firearm blueprints via algorithm. Non-compliance would be classified as a class C felony, carrying a maximum 5-year prison sentence and $15,000 fine.

Manufacturers could meet compliance through firmware integration, preprint software with detection capabilities, or handshake authentication protocols. The law would take effect July 1, 2027, applying to any entity selling 3D printers in the state.

New York recently introduced similar legislation targeting 3D-printed gun restrictions, suggesting growing regulatory momentum. However, Washington’s approach introduces stricter penalties and specific technical requirements.

The $15,000 fine and 5-year prison term could deter smaller manufacturers from entering the market, while larger firms might absorb costs through compliance upgrades. Consumer access to 3D printers may shrink as vendors prioritize legal compliance over affordability.
