Some people are making guns with 3D printers. A new law seeks to cancel their print jobs

New York is considering a law requiring 3D printers sold for home and business use to include technology blocking gun production, aiming to combat 'ghost guns' used in crimes. Similar measures are under review in California, with concerns about the technology's effectiveness and privacy rights. Privately made firearms recovered in crimes have risen sharply, including a 3D-printed gun linked to a 2024 UnitedHealthcare CEO killing.
