#gun control

California and New York are advancing legislation that would require 3D printers sold in their states to include software capable of detecting and blocking gun blueprints, with New York's law already signed and California's AB 2047 passing the Assembly. This legislation represents a significant intervention in the open-source 3D printing ecosystem and DIY culture, raising concerns about digital rights, censorship, and the potential for misuse beyond gun control, such as intellectual property enforcement. New York's law also applies to CNC machines, while California's AB 2047 would ban sale of uncertified printers after March 2029 with fines up to $25,000; critics warn the technology may inadvertently block everyday objects and require cloud scanning of user files.
