CA Bill: 3D Printers Must Detect Guns
20 Feb
Summary
- California bill requires 3D printers to have firearm detection.
- The legislation aims to prevent untraceable 3D-printed guns.
- Concerns raised over verification processes and potential bypassing.

A new bill in California, AB-2047, has been introduced by Assemblymember Rebecca Bauer-Kahan with the goal of preventing the creation of untraceable 3D-printed guns. This legislation mandates that all 3D printers sold within the state must incorporate "firearm detection algorithms." The proposed law aims to add a layer of technological security to block the production of illegal firearms.
Implementation of AB-2047 involves a new verification process, prompting criticism from entities like Adafruit, which suggests a state-maintained roster of approved printer models. The bill also stipulates that disabling the firearm-blocking software will be a misdemeanor, and vendors selling printers without the technology could face civil lawsuits. The Department of Justice or another state agency would oversee the certification of these algorithms.
