On March 14th, Professor Yan Yongnian, the founder of Laser Rapid Prototyping Center of Tsinghua University, the chief consultant of China 3D Printing Technology Industry Alliance, and the chairman of China Industrial 3D Printing Council, went to Guangxi University for the theme of "Principle and Application of Laser Metal Melting / Clad Technology Academic report. Professor Yan Yongnian said that China will become the world's largest civil aviation market. Metal 3D printing has a good prospect in the aero engine and gas turbine market. Aero engines / gas turbines are the most important application areas of metal 3D printing technology. They are designed and produced complex internal structures. The core technology of the engine.
Professor Yan Yongnian also introduced the application of 3D printed SLM technology in aero engine casings, jet engine fuel nozzles, satellites, and rocket manufacturing, and pointed out that 3D printed SLM technology is changing the status of high-end manufacturing aero engine manufacturing industry. He also talked about metal 3D Printing (ie, metal additive manufacturing or laser metal melting / cladding technology) is the principle and difference of traditional manufacturing technology, and the application of this technology in aero engine casing, jet engine fuel nozzle, satellite, and rocket manufacturing.
Finally, Professor Yan introduced the development of the ultra-large and high-efficiency SLM process and equipment of Jiangsu Yongnian Laser Forming Technology Co., Ltd. In the summary of the report, Professor Yan believes that 3D printing SLM technology is changing the status of high-end manufacturing aero engine manufacturing. The world's metal 3D printing is still in the development stage. It is still necessary to continuously research and improve the technology, and continue to improve it. 3D printing technology contributes to China's manufacturing and national defense.
