Abstract: Automobile manufacturing costs need to be continuously optimized and the manufacturing cycle is constantly compressed and optimized with the increasing competition in the automotive industry. Therefore, the 3D printing technology with efficient processing capacity, cost saving and lightweight characteristics has been increasingly applied and promoted in automobile manufacturing. This paper mainly studies the application scenarios of non-metallic 3D printing technology in the body shop, and analyzes its application characteristic. It provides a reference for the non–metallic 3D technology application in body shop of automobile manufacturing.
