California's AB-2047 bill could reshape 3D printing with firearm restrictions

California has introduced bill AB-2047, which could significantly reshape the state's 3D printing market. The legislation mandates that 3D printers incorporate special algorithms or software mechanisms capable of blocking the printing of firearm parts. Furthermore, it proposes that only models listed on an official approved device registry be permitted for sale.

This initiative largely mirrors similar bills previously proposed in Washington and New York, but the California version goes further. According to the text, the state's Department of Justice must develop certification rules for printers and their software by 2027. Manufacturers will be able to apply for approval, and from 2029, the sale of devices not included in the state registry will be prohibited.

The bill also outlines technical requirements for firmware and print preparation software. Specifically, printers will need to check print jobs via a built-in algorithm before starting work and only accept files from designated software, preventing system bypass. Attempts to circumvent these protective mechanisms would be deemed illegal.

Experts note that if such measures are adopted simultaneously in California, Washington, and New York, a significant portion of the American market would be affected. Together, these three states account for about one-fifth of the U.S. population and nearly a quarter of the national GDP. In that scenario, 3D printer manufacturers might face a decision: create separate device versions for these regions or reconsider their nationwide product strategy.
