3D printer filament (1.75mm diameter, blue; 1 kg spool); designed to fit most common 3D printers (check spool size for compatibility) Made of commonly used ABS, a strong thermoplastic material―great for creating durable items that require a higher resistance to heat Spool’s built-in gauge shows percentage of material remaining and approximate length remaining Engineered to reduce jamming; keep filament dry and away from UV light Note: Please refer to the filament parameter on the spool to configure your 3D printer settings correctly.
