Synthetic nylon polyamide 6 filament is strong and versatile, providing high inter-layer adhesion for 3D printing projects. Sensitivity to moisture is offset by durability, minimal shrinkage, and resistance to a range of chemicals, making it suitable for moving parts and heavy-duty components. This black 2.85mm filament on a 1kg spool offers excellent mechanical performance and dimensional stability, as well as low moisture absorption for warping prevention and consistent performance.
