In response to the rise of 3D printing technology, Washington state lawmakers have introduced two significant bills aimed at regulating the production of unserialized firearms, commonly referred to as "ghost guns." The legislation seeks to address the evolving capabilities of accessible manufacturing technologies.
House Bill 2320 specifically targets the creation of ghost guns by prohibiting the use of 3D printers or CNC machines for manufacturing firearms or their components without a license. It also establishes a legal presumption of criminal intent for those found with relevant manufacturing codes without proper authorization. Meanwhile, House Bill 2321 mandates that all 3D printers sold in the state must include software to detect firearm blueprints, preventing unauthorized printing.
The initiative, led by Rep. Osman Salahuddin (D-Redmond), is a response to alarming incidents involving firearms with 3D-printed parts. Salahuddin highlighted a case from September 2025 when law enforcement discovered over 23 firearms from a minor, underscoring the potential risks associated with unregulated access to this technology. This follows previous laws enacted in 2019 and 2022 aimed at controlling the proliferation of ghost guns in the state.
