Kingroon High Speed PLA 3D Printer Filament, 3D Printer Rapid Filament for 30-/s Hyper Printing Filament, Dimensional Accuracy +/-, 3 kg Plastic Spool (6.6lbs（Red&Green&Blue）

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.
