S2165 3D Printed Gun Safety Act of 2025

Direction

Firearms weapon accessory restrictionsAI label

Restricts gun access model confidence 90%

Prohibits distributing 3D printer files that can automatically produce firearms or complete them from unfinished frames/receivers, so fewer untraceable or undetectable guns can be made and distributed.

It shall be unlawful for any person to intentionally distribute, over the internet or by means of the World Wide Web, digital instructions in the form of Computer Aided Design files or other code that can automatically program a 3-dimensional printer or similar device to produce a firearm or complete a firearm from an unfinished frame or receiver.

Firearms otherAI label

Restricts gun access model confidence 80%

Prohibits distributing 3D printer files for firearms to reduce untraceable guns that evade background checks, serial-number tracing, and metal detectors, thereby limiting access by prohibited persons.

The availability of online schematics for the 3D printing of firearms and firearm parts increases the risk that dangerous people, including felons, domestic abusers, and other people prohibited from possessing firearms under Federal law, will obtain a firearm through 3D printing.

Firearms purchase background checksAI label

Restricts gun access model confidence 70%

Highlights how 3D-printed guns allow prohibited persons to evade background checks (as in the Santa Monica example) and aims to curb that by banning distribution of the files, so fewer such evasions.

The person had failed a background check when he tried to purchase a gun from a licensed gun dealer. The gun he used was made from an unfinished AR-15-style receiver, similar to a receiver that can now be made with a 3D printer.

Why the model tagged it this way: The bill adds a prohibition in 18 USC 922 on distributing CAD files or code that can 3D-print firearms or complete them from unfinished receivers, directly restricting access to and manufacture of such weapons; findings emphasize risks of evading background checks, serial-number tracing, and detection, supporting the firearms tags with no provisions on transgender, abortion, or immigration topics.
