Brickbat: Ghost in the Machine
San Diego County, California, has sued Polymaker, a company that manufactures filament for 3D printers. The lawsuit accuses the company of illegally marketing its products to people who make unregistered firearms, often called "ghost guns." The county admits that the filament itself is legal but objects to how the company markets it. The lawsuit alleges that Polymaker worked with a firearm-printing influencer, promoted products for making guns, and provided technical advice to online communities interested in 3D-printed firearms. The county argues that this marketing violates California consumer protection laws. It is seeking the return of revenue linked to the allegedly illegal marketing, a court order stopping the company from continuing the challenged practices, and civil penalties of up to $2,500 per violation—with each day counting as a separate violation.
