摘要:
以太阳帆深空探测为引子,对以在轨3D打印及装配技术为基础的在轨制造技术的必要性和可行性进行分析,分别阐述了在轨3D打印技术的技术优势、技术可行性以及在轨装配的最新研究进展,并重点研究了美国NASA资助的“蜘蛛制造”在轨制造技术,此项研究成功地将在轨3D打印和空间自主装配有机结合起来,有望突破目前空间可展开机构无法达到万米量级的技术局限性,为中国深空探测的发展提供了一种可供选择的发展思路。

Abstract:
The solar sails for cost reduction become the trend and research focus of the world in deep space exploration in recent years, and the technologies of how to manufacture and deploy an extremely large scale deployment structure such as solar sail are particularly important, The self-fabrication space technologies based on on-orbit 3D printing and space assembly can provide an available research feasibility for our study. In this paper, the advantage and the feasibility of the on-orbit 3D printing technology is summarized firstly, and then the latest research achievements of on-orbit space assembly technology are introduced. The SpiderFabTM on-orbit manufacturing technology sponsored by NASA Innovative Advanced Concepts (NIAC) is introduced to break through the technical limit of traditional deployment structure with 10 000 m2 size. After which, the on-orbit manufacturing technology may provide an available direction for future deep space exploration research.
