LulzBot Taulman Alloy 910 Nylon 3D Printer Filament, 1 lb. Reel, 3 mm, Natural Hot-end print temperature 245-250C Incredibly resilient, stiff, and strong Comparable to polycarbonate, easier to print and almost as strong With a tensile strength of 8,500 PSI when 3D printed, Alloy 910 is almost as strong as polycarbonate. Unlike polycarbonate that requires a hot-end capable of reaching near 300C Perfect for printed objects that need to be strong and stiff like enclosures, high-impact parts, and even mechanical linkages used in robotics and production environments
