Anycubic PA6-CF Carbon Fiber 3D Printer Filament, 0.5KG, Black

A hardware brand first — Anycubic made its name on printers like the Photon and Kobra before building out a proper filament catalog. PLA, PETG, ABS, ASA, and a high-speed variant are all covered, priced at the low end of the market. Big direct store with Amazon stock too.
