Analysis of Research Status on In-situ Fabrication and Repair Technology in Space

The conception and characteristics of In-situ Fabrication and Repair （ISFR） technology in space were introduced in this paper. Then the background, current status and future trend of ISFR were explained in detail including the, in-situ fabrication technology represented by selective laser sintering and electron beam melting, soldering in space, building technology of space base and the utilization of in-situ resources. According to the development of Chinese space technology, sug- gestions such as referencing the technology achievements abroad, focusing on the space environment adaptation and application verification of main materials used, and studying the in-situ fabrication technology with simulated lunar soil were put forward.
