The PET base brings low moisture sensitivity (relative to nylon), high strength, creep resistance, good chemical resistance and high heat resistance; the 15% chopped carbon fiber adds stiffness and a matte finish while suppressing PET's tendency to warp. Phaetus's \"Smart Fiber Reinforced Technology\" forms a fiber mesh inside the material so prints stay dimensionally stable with minimal shrinkage.
