The California State Assembly has passed a bill that mandates 3D printer surveillance software, despite warnings from the Electronic Frontier Foundation (EFF) about its dangers and impracticality [1]. The bill, AB 2047, targets 3D printers for the rare and already outlawed practice of manufacturing firearms without a license. However, its implementation may harm law-abiding users and threaten their privacy and choice. The scheme mandates print-blocking algorithms that can be easily circumvented, and its effectiveness is questionable [2].

The EFF has expressed concerns that the bill will not only criminalize the use of open-source 3D printer firmware but also enable print-blocking algorithms to parallel anti-consumer behaviors seen with DRM [3]. The bill's amendments have not addressed the risks to privacy, speech, and consumer rights, and its implementation may have unintended consequences. As the bill heads to the state senate, it is essential to renew the call on legislators to drop it and protect the tools of creators in the state. The proposed scheme may also have implications for the broader tech industry, as it sets a precedent for government-mandated surveillance and control of emerging technologies.

The EFF has urged the public to take action and tell their senators to stand with creators and oppose the bill [4]. In conclusion, California's proposed 3D printer surveillance scheme is a misguided attempt to regulate emerging technologies, and its implementation may have far-reaching consequences for privacy, choice, and innovation.
