The PC family covers polycarbonate-based engineering thermoplastics developed for demanding FDM applications. Polycarbonate combines high toughness, impact resistance, mechanical strength and elevated-temperature performance. It is commonly selected when PLA, PETG or standard general-purpose materials cannot provide the required structural or thermal performance. PC requires controlled material drying, stable processing conditions and careful management of part orientation and thermal contraction. Final performance depends on the selected grade, geometry, wall design, print orientation, operating environment and production parameters.
