Abstract: In-space additive manufacturing technology is a “space 3D” printing technology,which has attracted major attention due to its application in on-orbit manufacturing and space base additive manufacturing.The basic concepts were introduced and the progress of space on-orbit additive manufacturing technology in the world was summarized.With the requirement of space stations and on-orbit spacecraft,the significant challenge of in-space additive manufacturing was the raw materials,printing technology and equipment.This was attributed to the unique feature of the space environment,including microgravity and high vacuum,etc. Finally,based on the current development status,requirements,and possible implementation paths of in-space onorbit manufacturing technology,the development direction of in-space additive manufacturing was pointed out.

Key words: on-orbit manufacturing, space environment, mission requirements, space applications
