空间增材制造技术的应用

中国空间站旨在进行大量在轨科学实验和空间应用研究，在轨保障是支持空间站在全寿命周期内完成载人航天任务的重要途径.传统地面制造及上行补给方式难以满足较大规模应用的需求，亟需一种创新性的保障模式突破资源瓶颈，空间增材制造技术具有极大的潜力实现即造即用的资源保障模式.本文根据空间增材制造技术的最新研究进展，结合中国空间站和载人深空探测任务需求，对空间增材制造技术的在轨应用模式进行分析，提出了中国空间增材制造技术未来发展所面临的问题和解决途径. 

Application of Additive Manufacturing Technology for Space

Chinese Space Station has planned a large number of scientific experiments and applied research. On-orbit support is critical for the accomplishing of manned space mission during the full life cycle of space station. Nevertheless, resources supplied by cargo aircrafts are difficult to be sustainable. The space additive manufacturing technology is a revolutionary and strategic technique for future space exploration, which has the potential to realize manufacturing on the station demand, and will facilitate deeper space exploration by saving logistics from Earth. 3D printing is an important modeling technique to support space manufacturing with its efficiency and flexibility. The latest research of the on-orbit additive manufacturing is summarized, and its on-orbit application pattern is analyzed by taking account of the requirements of Chinese space station and its manned space missions. Moreover, the challenges and solutions of applying additive manufacturing on-orbit are analyzed.
