Kingroon PA6-CF Filament, Carbon Fiber Nylon 6 3D Printer Filament, High Strength High Rigidity Heat Resistant for Functional Parts and Industrial Tooling, 1kg (2.2lbs) Black Filament

Budget hardware maker that sells filament alongside its printers. Prices are low; the catalog sticks to standard PLA, PETG, and a few specialty variants. Not the place to shop for engineering materials.
