With the continuous maturity of 3D printing technology, the continuous breakthrough in the research and development and application of printing materials, and the obvious advantages of 3D printing technology in the early stage of research and development and trial production, such as low cost, high efficiency and easy modification, the machining industry pays more and more attention to 3D printing technology, and has taken this technology as a practical choice for few-quantity production of special parts. 3D printing has significant advantages in the processing and manufacturing of parts and components with small batches, diversity, special materials and complex shapes. Personalized products are designed according to customers' needs, and multiple products are produced in the same version. Spare parts manufacturing can solve or verify multiple problems and reduce the occupation of capital, space and production capacity.
