Reject AB 2047: California’s Attack on 3D Printers, Creators, and Open Source
California lawmakers are advancing A.B. 2047 toward a floor vote in the State Assembly within the next few weeks. The bill would require 3D printers sold in California to run government-approved software that scans every print and leaves it up to unproven algorithms to identify blueprints which could be firearm components. The real impact however is surveillance, manufacturer lock-in, and censorship without recourse — while the scheme is easily bypassed by people already willing to break existing law by producing firearm parts.
Unlike similar bills, A.B. 2047 goes as far as criminalizing individual users who disable or modify these systems, implicating the open source community and any users or developers who create or use third-party tools.
This bill won’t stop ghost guns, and it’s not about safety. This law demands an unfeasible tech solution for something that is already illegal, and is an attack on user control over devices they already own. California legislators are handing a huge gift to printer manufacturers looking to lock-in users. Creators across the state, from engineers to costume designers, will be stuck with fewer choices, new inconveniences, and enshittification driving up costs and surveillance risks.
California is not merely another state market. It is large enough to set defaults for the entire technology industry. We need to stand with grassroot innovators and demand that the legislature reject A.B. 2047.
