We Can Still Stop California’s 3D Printer Surveillance Scheme
Rory Mir and Cliff Braun · 2026-06-26 · via Electronic Frontier Foundation

Ignoring EFF’s warnings about the dangers and impossibility of implementing a new mandate for 3D print surveillance software, the California State Assembly has signed off on legislation to do just that. In the process, legislators amended the bill to make it even more confusing, while failing to address the risks to privacy, speech, and consumer rights. We must renew our call on legislators to drop this bill as it heads to the state senate, and protect the tools of creators in the state.

What’s changed about the bill?

Since we first wrote about AB  2047, a bill targeting 3D printers for the rare, impractical, and already outlawed practice of manufacturing firearms without a license, it has picked up several amendments. Some are welcome changes, but most have only highlighted the technocratic absurdity of the proposed scheme. Our core concernsthat this mandate censors lawful speech, builds out corporate surveillance, and criminalizes open source experimentationhave not been remedied. 

Removes criminalization of resale

Starting with one silver lining, the current bill includes a carveout for the private resale of devices. The original bill would have made it a criminal offense for an individual to resell 3D printers purchased before this mandated censorship and surveillance software. This is a clear win for the 3D-printing community, but it is unfortunately not enough.

Ineffective carveouts for open source

One of the most dangerous aspects of the bill is that it criminalizes individual users for common practices, like creating and using alternative open source programs with their 3D printer. New amendments provide a carveout for the use of an open source tool, but only if it includes compliant censorship software. The bill burdens open source developers with ambiguous and unrealistic standards for print blocking, and continues to create a chilling effect for open source users.

Removes any actual requirement to work

To reiteratethere is no world where the mandated technology actually works as intended. It will both block lawful use of 3D printers, and allow firearms to be printed by anyone determined to do so. There is no amendment that can change this reality.

Instead, the current bill simply drops the pretense that this mandate is expected to work. The performance standard of algorithms changed from “effectively prevent[ing] a technically skilled user from evading [the algorithm]” to “substantially reduce the likelihood of foreseeable circumvention attempts…” The bill will still require all prints to be surveilled, but instead of testing efficacy against a skilled user, it just plays whack-a-mole with the (literally) infinite number of circumventions that any user can employ. 

Further, the bill now leaves us with an unclear process that relies on non-governmental third parties to define standards, and now relies on manufacturers and resellers to self-police.

Hollywood gets a cut

The bill includes yet another carve out for commercial users. This time for the entertainment industry, which makes extensive use of 3D printers for props and costumes. 

That’s fine for big studios, but it leaves out indie filmmakers, cosplayers, and many other small creators. 

This is simply a defensive edit to limit corporate opposition. There isn’t a clear division in 3D-printing between consumer and commercial tools. These are general purpose tools which might be picked up by a prop department of a big studio, or an artist getting ready for Comic Con. Indeed consumer level products are not only used by amateur artists and engineers developing their skills. Commercial 3D printers, like their traditional 2D equivalents, are frequently used in workplaces, as well as by professionals honing their skills or just trying to get some work done at home. 

Commercial carveouts hands printer manufacturers the ability to sell a more expensive tier of printers, locking-in and up-charging their commercial customers. Some of those customers will choose to buy general retail versions, but that carries its own price: increased risk of IP theft as all printed files are surveilled the same way they are for hobbyists. That means a real risk of businesses leaking any prototypes or new designs to not only the printer manufacturer, but potentially snooping governments and/or the general public through data breaches.

Demand  your senator oppose AB 2047

This updated version of AB 2047 downgrades performance standards and removes oversight while still threatening privacy and choice for users of 3D printers. A printer surveillance system won’t work for its intended purpose, and will only harm law abiding users. 

Act now to demand your senators to vote no on this ineffective and invasive bill.
