California's 3D printer surveillance bill advances despite privacy concerns
Original: We can still stop California's 3D printer surveillance scheme
Why This Matters
Surveillance mandate threatens open source innovation and consumer privacy while risking ineffective regulation of 3D printing technology.
The California State Assembly approved legislation mandating surveillance software on 3D printers to prevent unlicensed firearm manufacturing. The EFF warns the bill censors lawful speech, enables corporate surveillance, and criminalizes open source use despite amendments addressing some concerns.
The California State Assembly has approved AB 2047, legislation requiring 3D printer surveillance software to prevent the unlicensed manufacturing of firearms. The Electronic Frontier Foundation (EFF) warned legislators about the dangers and implementation challenges of the mandate, but the bill advanced with amendments that, according to the EFF, created additional confusion while failing to address core privacy and free speech risks. Recent amendments include a carveout removing criminal penalties for private resale of 3D printers purchased before the mandate takes effect—a win for the 3D printing community. However, the EFF identified critical remaining flaws. New amendments provide a carveout for open source tools, but only if they include compliant censorship software. This burdens open source developers with ambiguous standards and creates a chilling effect for users. The EFF emphasizes the fundamental problem: no technical solution can reliably block only illegal firearm printing while allowing lawful 3D printer use. The bill will both block legitimate uses and fail to prevent determined bad actors from printing firearms. The EFF called on California state senators to reject the legislation and protect creators' tools.
