Abstract: |
This paper briefly introduces the concept of 3D printing technology, describes in detail the current situation of 3D printing materials, equipment and its main application in aerospace. By comparing with traditional manufacturing, the advantages of 3D printing are summarized. The paper puts the emphasis on manufacturing of honeycomb panel, truss, large antennas and other spacecraft complex components and facilities, and an integral forming process and on-orbit manufacturing by using 3D printing are proposed. Considering the status of spacecraft equipment manufacturing and 3D printing technology capabilities, it is concluded that 3D printing research on complex and difficult-to-machine components of satellite could be carried out recently, then in the middle and long term, we should aim at on-orbit maintenance of manned space station and deep space exploration. |
