Untraceable 3D-printed guns are rising rapidly in U.S. cities, evading federal oversight and prompting calls for stronger laws and tech industry action.
Gun safety advocates warn of a sharp rise in untraceable 3D-printed firearms across U.S. cities, with law enforcement reporting hundreds of recoveries—up from fewer than 30 in 2020—due to widespread access to affordable 3D printers and online gun blueprints.
Unlike regulated ghost-gun kits, these weapons evade federal oversight because they are not produced through traditional channels, leaving the ATF without authority over printer makers or digital platforms.
While 2022 federal rules require serial numbers and background checks for certain kits, they don’t apply to 3D-printed guns.
Officials, including Manhattan District Attorney Alvin Bragg, are pushing tech companies to remove blueprints and adopt detection software, with some printer manufacturers adding firmware to block gun part prints.
Advocates stress the need for stronger laws and industry cooperation to prevent misuse without restricting legitimate 3D printing.
Las armas imprimidas en 3D no rastreables están aumentando rápidamente en las ciudades de EE.UU., eludiendo la supervisión federal y provocando llamados a leyes más estrictas y acciones de la industria tecnológica.
