California sues Polymaker over 'ghost gun' filament marketing

The State of California has filed a lawsuit against 3D printer filament manufacturer Polymaker, alleging that the company illegally marketed its products to the "ghost gun" community. The lawsuit, filed by San Diego County Counsel, claims Polymaker transformed harmless PLA filament into a regulated "firearm precursor part" by appealing to gun enthusiasts. Prosecutors point to Polymaker's hiring of social media personality Sean Aranda, known as "The 3D Print General," who was previously banned from YouTube for firearm policy violations, as evidence of the company's intent to cultivate this market.
