Overview

POLMASK Polymaker Fiberon PA612-CF15 is a high-performance 3D printing filament engineered for professionals who need strength, heat resistance, and reliability. The filament combines polyamide 612 (nylon 6/12) with 15% carbon fiber by weight, resulting in a material that is both stiff and tough. With a diameter of 1.75 mm and a tolerance of ±0.05 mm, it ensures consistent extrusion and high-quality prints. The spool contains 0.5 kg of filament, vacuum-sealed with desiccant to protect against moisture.
