3D Printed Gun Safety Act of 2025

Summary

Makes it a federal crime to intentionally post or otherwise distribute online digital instructions—such as CAD files or code—that can automatically program a 3D printer or similar device to produce a firearm or to finish an unfinished firearm frame or receiver. The bill frames the change as a public-safety measure to prevent production of untraceable or metal-detector‑evading firearms, and it adds the prohibition as a new subsection to 18 U.S.C. § 922.

• Creates a federal crime to intentionally post or distribute online files or code that automatically program 3D printers or similar devices to make firearms or complete unfinished firearm parts.
• Targets digital instructions such as CAD files or other machine‑readable code delivered over the Internet or World Wide Web.
• Congressional findings justify the prohibition on public-safety and national-security grounds, citing incidents and trace data about untraceable or undetectable firearms.
• Focuses on intentional distribution; the statutory text emphasizes the distributor's intent as an element of the offense.
• Does not include penalty amounts, enforcement funding, or implementation timelines in the provided sections.
• Raises likely legal and technical challenges around definitions (what counts as covered code), intent proof, dual-use materials, and First Amendment questions.
• Will affect a range of actors: people who post/design distribution files, online platforms that host files, 3D-printing businesses, and law enforcement agencies tasked with investigations.
