Michael Bloomberg is Behind the Push to Let the Government Decide What You Can Make on Your 3D Printer

Michael Bloomberg’s fingerprints are all over the latest scheme to turn every 3D printer into a government-monitored workstation, and the 2A community should recognize the move for what it is: an attempt to choke off the decentralized future of firearms before it fully arrives. By pushing “spyware” mandates that would force printers to log, report, or even refuse jobs involving certain files, Bloomberg is betting that most Americans won’t notice until the infrastructure is already in place. The same billionaire who once tried to buy mayoral control of entire cities is now trying to buy regulatory control of what can and cannot be fabricated in a garage, and the target is obvious—home gunsmithing that bypasses both background checks and the commercial supply chain. What makes this especially dangerous is how quietly it could be implemented. Instead of a flashy new ban, the strategy is to embed compliance software at the hardware or slicer level, sold to the public as a safety feature while quietly giving federal agencies a kill switch on unapproved designs. That’s a direct assault on the core 2A principle that the right to keep and bear arms includes the right to manufacture them, a right the Founders took for granted when every blacksmith could forge a musket. If Bloomberg’s vision wins, the next generation of innovators won’t be experimenting with new receiver geometries or suppressor baffles; they’ll be navigating terms-of-service agreements written by the same people who spent decades trying to make “assault weapon” a permanent legal category. For gun owners, the takeaway is straightforward: any technology that lets one unelected donor redefine what is printable is a technology that can be turned against every other form of private manufacturing. The 2A community has already watched magazines, pistol grips, and now braced pistols get redefined by regulatory word games; letting the same crowd redefine CAD files is simply the next logical step. The defense isn’t louder lobbying in Washington—it’s accelerating open-source development, maintaining offline design libraries, and making clear that any printer requiring a government backdoor is a printer the community will refuse to buy.
