California's 3D Printer Surveillance Bill: Why AB 2047 Must Be Stopped

• The California State Assembly has passed AB 2047, a bill mandating surveillance software for 3D printers, despite warnings from the EFF regarding privacy, free speech, and technical infeasibility.
• The bill is currently heading to the state senate, and advocates are calling for its rejection.

Legislative Amendments and Flaws

• The bill removes the criminalization of private device resales, but other significant issues remain unresolved.
• Open-source carveouts are effectively neutralized because they require the inclusion of mandatory censorship software, placing an unrealistic burden on developers.
• The performance standard for surveillance algorithms has been downgraded from requiring the effective prevention of evasion to simply reducing the likelihood of foreseeable circumvention, admitting the scheme's fundamental inability to work.
• A new carveout for the entertainment industry protects major studios but excludes indie filmmakers and independent creators, functioning primarily as a defense against corporate opposition.

Consequences for Privacy and Innovation

• General-purpose 3D printers do not have a clear division between commercial and consumer use; the law forces businesses to choose between paying for expensive commercial-tier printers or using retail versions that expose prototypes and designs to potential data breaches.
• The mandated surveillance creates a chilling effect on open-source experimentation and threatens the privacy of all lawful users.
• The bill fails to provide a viable security mechanism for its stated goal of preventing illegal firearm manufacturing while imposing invasive oversight on the creative community.
