GoKawiilCalifornia sues Polymaker over filament marketing to 3D-printed gun community
San Diego County Counsel filed a civil lawsuit on October 5, 2026 in San Diego County Superior Court against Polymaker LLC, the Shanghai-based filament maker with U.S. operations in Houston. The complaint alleges Polymaker's marketing, including hiring 3D-printing figure Sean Aranda ("The 3D Print General") after his 2023 YouTube ban over firearms content, effectively turned its PLA filament into a regulated firearm precursor part under California law. The state seeks disgorgement of profits, civil penalties and injunctive relief.
