Abstract:

In the high energy beam metal additive manufacturing technology, the laser and electron beam are used as the heating source to realize the manufacture of metal parts by powder melting or fuse deposition modeling. Based on the development of the metal additive manufacturing technology in the field of space, combining with the higher requirements of the on-orbit equipment size, weight, power consumption and life span induced by the strong constraints of space station and deep space exploration, the two working modes of the laser and electron beam heating sources are compared,and the on-orbit feasibility is analyzed. Moreover, the problems as well as the solutions to the development of future space metal additive manufacturing technology are presented.

Key words: Laser, Electron beam, Fused deposition modeling, Space metal additive manufacturing
