摘　　要：近年来,增材制造技术在载人航天工程中的应用迅速发展。对熔融沉积成型技术、激光选区熔化技术、线材电弧增材制造技术、热喷涂增材技术、月壤增材制造技术等用于载人航天工程的增材制造技术及这些技术的应用领域进行了总结。对增材制造技术在在轨制造飞行器替换件、制造大型桁架等难以在地面制造或发射的部件、制造飞行器复杂部件等应用领域进行了总结。提出未来载人航天工程技术的增材制造中应发展适合载人航天工程的材料体系,应研究微重力环境下的增材制造技术,同时未来还应发展相关工艺。In recent years,the application of additive manufacturing technology in manned space engineering has developed rapidly.This paper summarizes the additive manufacturing technologies used in manned space engineering,such as fused deposition modeling technology,selective laser melting technology,wire and arc additive manufacturing technology,thermal spraying additive technology,lunar soil additive manufacturing technology and their application fields.This paper also summarizes the application fields of additive manufacturing technology in onorbit manufacturing of aircraft replacement parts,manufacturing of large truss and other components that are difficult to be manufactured or launched on the ground,and manufacturing of complex aircraft components.Finally,this study makes the case that in order to implement additive manufacturing in the future,a material system appropriate for manned space engineering must be developed.Additive manufacturing in a microgravity environment should be studied.Also,relevant processes should be developed in the future.
