Problems solved by technology

[0005] However, the usual 3D laser sintering printers are extremely expensive due to their complex structure, and there are microscopic pores in the sintering process of metal raw material powders, which damage the mechanical properties of metal products. These seriously affect the application and popularization of metal 3D printing production technology. High-performance and low-cost metal 3D printer technology and equipment have become one of the keys to the development of the industry
