KINGROON 16KG PLA Filament Bulk Bundle, 16 Pack (8 Basic PLA & 8 Tri-Color Silk Spools), Dimensional Accuracy +/-, Tangle-Free 3D Printing Materials for Print Farms & Creators

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.
