California Assembly passes 3D printer bill that would criminalize bypassing mandated gun-blocking software
The California Assembly has passed AB 2047, a bill aimed at regulating 3D printers by requiring them to include firearm-blocking technology. This legislation makes it a misdemeanor to disable such technology, which has raised concerns among advocates for open-source firmware. The bill now moves to the state Senate for further consideration.
- ▪AB 2047 mandates that all 3D printers sold in California must include firearm-blocking technology.
- ▪Disabling or circumventing this technology would be classified as a misdemeanor under the new law.
- ▪The bill aims to address the rise in 3D-printed firearms, which have increased significantly in recent years.
