California moves to ban the sale of 3D printers without a "firearm blueprint detection algorithm."
California is moving to ban the sale of 3D printers that do not include a firearm blueprint detection algorithm. This legislation aims to prevent the production of untraceable firearms, known as 'ghost guns.' The bill has sparked controversy over concerns regarding innovation and consumer rights.
- ▪The proposed ban would require all new 3D printers sold in California to have a mandatory detection algorithm to block firearm printing.
- ▪The bill, known as AB-2047, has passed the assembly and is pending Senate review before reaching Governor Gavin Newsom.
- ▪Critics argue that the legislation could impede innovation and lead to government overreach in consumer purchases.
