As concerns over 3D-printed firearms continue to escalate, Washington state has proposed new legislation aimed at regulating their manufacture. A bill introduced last week, known as HB 2321, would require all 3D printers sold in the state to be equipped with technology that prevents them from printing firearms or unauthorized firearm components.
The proposed law mandates that, effective July 1, 2027, no manufacturer or vendor of 3D printers can sell their products in Washington unless they include “blocking features.” These features are intended to detect blueprints for firearms, effectively restricting users from bypassing the safeguards. The bill suggests implementing a firearms blueprint detection algorithm that would be an integral part of the printer’s firmware or software.
If enacted, any 3D printing company that violates this law could face significant penalties, including up to five years in prison and fines reaching $15,000.
Washington’s legislative move follows similar actions taken in other states, such as New York, which has proposed laws to ban 3D-printed guns altogether and strengthen regulations surrounding gun-related blueprints. As states increasingly grapple with the implications of 3D printing technology in firearm manufacturing, Washington’s bill marks another step in a broader national discussion on gun control and public safety measures related to emerging technologies.
