TECHNOLOGICAL CAPABILITIES OF EFFICIENT USE OF ADDITIVE TECHNOLOGIES IN MANUFACTURE OF MACHINE PARTS

Recommendations on equipment selection are made, theoretical considerations on designing 3D printer for manufacture of parts by additive technologies are presented, and examples of parts and their application in machine building are given. The experimental model of the printer named TECHNOTOP RUDN is proposed: it has the best price/quality ratio, simple in use, has improved configuration and is an optimal alternative for discrete application. The strength and precision of the machine tool are analyzed as functions of the type of transmission, step motors, their capacity and operating modes. Thermal experiments and calculations of extrusion machine with a thermal barrier made of different materials are carried out. The pressing problems are solved, as well as defects and nuances of program settings during 3D printing are identified.

Keywords

Additive technologies, thermal experiments, printing techniques, selective laser sintering, direct material settlement, thermal barrier, material extrusion, thermal conduction, conventional technologies, three-dimensional printing.
