| Abstract: |
| In-space manufacturing technology holds extensive application prospects in deep space exploration and future aerospace activities, representing an advanced technology being actively developed by major space-faring nations. This paper begins by analyzing the development background and practical significance of space manufacturing technology, elucidating its core concepts and systemic composition. Based on this foundation, it reviews the current research status of both on-orbit manufacturing technologies and in-situ resource utilization (ISRU) techniques for extraterrestrial bodies. The study systematically summarizes key areas of focus in space manufacturing, including on-orbit material production, on-orbit additive manufacturing, on-orbit equal-channel manufacturing, on-orbit connection and repair, on-orbit assembly and inspection, extraterrestrial resource in-situ extraction-utilization, and extraterrestrial facility in-situ construction. It also identifies a series of technical challenges encountered during the development process and distills future trends for this technology. By analyzing the developmental trajectory of space manufacturing technologies both domestically and internationally, as well as the differences in research focus between the two, the paper provides recommendations for advancing China’s space manufacturing capabilities from three perspectives: mission-driven development, infrastructure construction, and standardization. These insights aim to offer valuable references for strategic planning in the advancement of space manufacturing technology. |
