AddNorth PC Blend HT LCF is a long carbon fiber reinforced polycarbonate designed for extreme stiffness and high temperature resistance. In this video, I test how far those claims go — from tensile strength and layer adhesion to impact resistance, creep, and heat performance.
Is this really one of the strongest and stiffest PC-CF filaments I’ve tested so far? Let’s find out.
