Metal 3D printing technology has unique advantages in manufacturing complex structures and high-performance parts, and has been widely used in aerospace, energy power, automotive manufacturing, mold manufacturing and other fields. Designers can be based on additive thinking, to achieve high-performance materials, typical structures, complex structures, integrated optimization design, to meet the requirements of lightweight weight reduction at the same time, to ensure that the use of high temperature and high pressure and other extreme environmental performance.

　　In the field of aerospace, metal 3D printing technology facilitates the manufacturing of aviation engines and other parts with complex internal features and thin-walled structures, but in practical applications, many parts need to be made of multiple materials coupling, which also puts forward higher requirements for metal 3D printing technology.

　　LiM Laser team combines laser selective zone melting and laser cladding technology to successfully manufacture high-performance complex structure aero-engine thrust chamber parts.

　　The part has many fine structures with complex internal runners and thin-walled structures, and is manufactured using a variety of additive processes.

　　First use LiM-X260 equipment to complete the copper alloy (CuCrZr) laser selective melting forming, followed by the use of laser cladding technology to add high-temperature alloy (GH4169) cladding layer on the external surface to achieve the purpose of the surface modification to achieve the functional structure of copper alloys and high-temperature alloys of the integration of the gradient additive manufacturing, and the final product has both high thermal conductivity and high strength performance.

　　The part realizes the structure-function integrated additive manufacturing of the thrust chamber components, proves the manufacturing potential of multi-alloy, multi-process combination 3D printing, and provides a new manufacturing idea for the rapid development of low-cost, high-quality parts.

　　Metal 3D printing technology has greatly improved the aerospace, energy power and other high-end manufacturing areas parts design freedom and product development iteration speed. However, how to use the technology low-cost, high-efficiency, high-quality production of complex structural components, there is still a broad space for exploration. As an advanced enterprise in the metal 3D printing industry, LiM Laser will solidly promote technological innovation, crack the process problems, tap the application demand, and continuously provide more targeted metal 3D printing solutions for users in various fields to empower the development of the industry.
