Feature Introduction:
PET K7CF is a carbon fiber-reinforced PET material with high stiffness, rigidity, strength, and wear resistance. As an entry-level high-performance FDM filament, it is easy to print without rigorous printing conditions. Compared with PA/CF, PET K7CF is less absorbent and more applicable to high-performance structural parts.
