Description Nylon PA6 Low Warp CF15S is a strong and low-shrinkage material that has the advantages of carbon fibers. In addition, it is stiff, dampens vibration and is wear-resistant. This filament is resistant to chemical materials and has a consistent operation, even at higher temperatures up to 180 ˚ C. This makes the material an ideal choice for 3D prints that must withstand heavy conditions. The filament is specially designed for better flow, resulting in better adhesion. Thanks to the 15% added carbon fibers, the stiffness and tensile strength have been significantly improved. Finally, the carbon fibers give the filament a matte look, making the layer lines less visible. This filament is 1.75 mm, comes in the color Black and has 0.5 Kg on the spool.
