California Bill Would Force 3-D Printers to Block Ghost Guns as Hollywood Warns of 2029 Sales Ban
2 articles · Updated · Los Angeles Times · Jul 19
Summary
AB 2047 would require 3-D printers sold in California to use software that blocks triggers and other gun parts, with noncompliant machines barred from sale or transfer starting in December 2029.
Lawmakers say the measure targets a sharp rise in privately made firearms recovered in crimes—up from more than 1,600 in 2017 to nearly 27,500 in 2023—with California leading the nation.
Hollywood effects studios, 3-D printing companies and civil-liberties groups argue the bill is too broad, saying it could block legitimate propmaking, expose design files and create a surveillance back door.
Backers including Assemblymember Rebecca Bauer-Kahan and Everytown say the software can save lives and does not transmit files, though critics note most ghost guns recovered by police come from kits or unfinished parts, not home printing.
The bill passed the Assembly in May and is moving through the Senate, where Bauer-Kahan says she is still working on changes after an entertainment-industry exemption failed to reassure studios using general-purpose printers.
If most ghost guns come from kits, will restricting 3D printers actually solve the problem?
Will software blocking ghost guns create a permanent backdoor for government surveillance?

California’s 3D Printer Ban on Ghost Guns: AB 2047’s Timeline, Legal Hurdles, and National Implications
Overview
California's Assembly Bill 2047 (AB 2047) targets the rise of untraceable, 3D-printed firearms by requiring all 3D printers sold in the state to include technology that blocks gun printing. Supporters believe this law is essential to close enforcement gaps, especially as law enforcement has seen a sharp increase in 3D-printed gun recoveries, including a major seizure in Santa Rosa and a 1,000% rise across 20 cities. The bill sets strict penalties for non-compliance and outlines a clear implementation timeline, reflecting California's proactive approach to addressing the challenges posed by emerging technologies and ghost guns.
