California’s bill, A.B. 2047, will not only mandate censorware — software which exists to bluntly block your speech as a user — on all 3D printers; it will also criminalize the use of open-source alternatives. Repeating the mistakes of Digital Rights Management (DRM) technologies won’t make anyone safer. What it will do is hurt innovation in the state and risk a slew of new consumer harms, ranging from surveillance to platform lock-in. California must stand with creators and reject this legislation before it’s too late.
3D printing might evoke images of props from blockbuster films, rapid prototyping, medical research, or even affordable repair parts. Yet for a growing number of legislators, the perceived threat of “ghost guns” is a reason to impose restrictions on all 3D printers. Despite 3D printing of guns already being rare and banned under existing law, California may outright criminalize any user having control over their own device.
This bill is a gift for the biggest 3D printer manufacturers looking to adopt HP’s approach to 2D printing: criminalize altering your printer’s code, lock users into your own ecosystem, and let enshittification run its course. Even worse, algorithmic print blocking will never work for its intended purpose, but it will threaten consumer choice, free expression, and privacy.
A misstep here can have serious repercussions across the whole 3D printing industry, lead the way for more bad bills, and leave California with an expensive and ineffective bureaucratic mess.
What’s in the California Proposal?
Compared to the Washington and New York laws proposed this year, California’s is the most troubling. It criminalizes open source, reduces consumer choice, and creates a bureaucratic burden.
Criminalizing Open Source and User Control
A.B. 2047 goes further than any other legislation on algorithmic print-blocking by making it a misdemeanor for the owners of these devices to disable, deactivate, or otherwise circumvent these mandated algorithms. Not only does this effectively criminalize use of any third-party, open-source 3D printer firmware, but it also enables print-blocking algorithms to parallel anti-consumer behaviors seen with DRM.
Manufacturers will be able to lock users into first-party tools, parts, and “consumables” (analogous to how 2D printer ink works). They will also be able to mandate purchases through first-party stores, imposing a heavy platform tax. Additionally, manufacturers could force regular upgrade cycles through planned obsolescence by ceasing updates to a printer’s print-blocking system, thereby taking devices out of compliance and making them illegal for consumers to resell. In short, a wide range of anti-consumer practices can be enforced, potentially resulting in criminal charges.
Independent of these deliberate harms manufacturers may inflict, DRM has shown that criminalizing code leads to more barriers to repair, more consumer waste, and far more cybersecurity risks by criminalizing research.
