New York state lawmakers are considering legislation that would require all 3D printers sold or delivered within the state to include “blocking technology” capable of preventing the production of firearms or firearm components. The provision is embedded within the state’s 2026-2027 executive budget bill (S.9005 / A.10005), specifically in Part C, and has drawn criticism from digital rights groups and makerspace advocates.
The “blocking technology” would function by scanning print files using a “firearms blueprint detection algorithm” before allowing them to be printed. If the algorithm identifies a file as a potential firearm or component, the printer would be prohibited from completing the print job. The bill does not specify which algorithm would be used, nor who would be responsible for maintaining and updating it.
Adafruit, a well-known online electronics retailer and open-source hardware proponent, has publicly warned of flaws in the proposed legislation. The company argues that the approach is fundamentally flawed, echoing concerns raised over a decade ago regarding Digital Rights Management (DRM) technologies. According to Adafruit, attempting to restrict the functionality of general-purpose computers – which 3D printers effectively are – is unlikely to succeed and could stifle legitimate uses of the technology.
Critics point to the potential for circumvention of the “blocking technology,” noting that blueprints can be altered or fragmented to evade detection. The effectiveness of such algorithms has been questioned, with concerns that they could generate false positives, preventing the printing of legitimate objects. Boing Boing reported that the bill’s language is broad enough to potentially impact a wide range of manufacturing and creative activities beyond firearms.
The legislation arrives as New York continues to grapple with gun violence and seeks to implement stricter firearm regulations. However, the focus on 3D printers reflects a growing concern over the potential for individuals to manufacture firearms outside of traditional regulatory frameworks. The New York Civil Liberties Union (NYCLU) is currently focused on issues related to buffer zones around houses of worship, indicating a broader legislative agenda concerning public safety and security.
As of February 13, 2026, the bill remains under consideration by the New York State Legislature. No public hearings have been scheduled to specifically address the 3D printer provision, and This proves unclear when a vote may be taken. The state budget is currently under negotiation, and the final form of the legislation remains subject to change.
