Kingroon Carbon Fiber PETG Filament 1kg (2.2lbs) Black, High Strength & Rigid 3D Printer Filament, ± Precision, Enhanced Flow & Smooth Printing for Functional Parts

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.
