California’s Assembly advanced AB 2047, a bill that would require 3D printers to use software that monitors prints and tries to block firearm-related designs. EFF says the amended bill still mandates surveillance of all prints, relies on vague third-party standards, and continues to pressure manufacturers, resellers, and open-source developers to implement or support filtering technology, even after changes carving out some resale and entertainment uses.
Why it matters: This is a security- and rights-relevant policy fight because it would normalize device-level monitoring of lawful activity and could burden open-source tools and creators far beyond its stated target. People in California, printer makers, and open-source developers may need to track the bill closely and oppose or prepare for compliance requirements if it advances.
