The study of the FDM technology of 3D printing with the use of materials for production tooling

The paper presents a comprehensive study of the surfaces of plastic samples (90% polysulfone (PSU) + 10% polycarbonate (PC)) modified with the help of an ultrasonic resonator to reduce friction in contact between the material of aluminum skins and a covering puncheon. Comparative characteristics of surfaces have been obtained, such as: microhardness, coefficient of friction and wear resistance in contact with wrought aluminum alloy D16T
