增材制造技术在载人航天工程中的应用与展望

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 on-orbit 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.
