Carbon-Fiber and Glass-Filled PETG
Chopped-fiber PETG gains stiffness, dimensional stability, and a matte finish but the fibers shred brass nozzles within hundreds of grams, demanding hardened steel or ruby nozzles and usually a 0.6 mm bore to resist clogging. Fibers improve stiffness along the extrusion direction while slightly weakening interlayer bonds.
