Additive manufacturing, commonly known as 3D printing, integrates computer-aided design, material processing and forming technology. Based on digital model files, special metal materials, non-metallic materials and medical biomaterials are stacked layer by layer through software and CNC system according to the methods of extrusion, sintering, melting, light curing and spraying to produce the manufacturing technology of physical goods.
Yueyang Luojia project team has made a lot of scientific research achievements in metal additive manufacturing technology, mastered the core technology of nondestructive testing, developed the first on-line monitoring device for metal additive manufacturing in China, and successfully passed the acceptance of the expert group of the Ministry of science and technology. The device can directly measure the defects online in the process of metal additive manufacturing, eliminate the defects in real time, and directly improve the quality of parts. The on-line nondestructive testing technology and laser shock strengthening post-treatment method are introduced into the additive manufacturing process to form a new defect free additive manufacturing technology. During the processing process, the laser shock strengthening post-treatment is detected, fed back and controlled. Through organic combination, a new additive manufacturing method and equipment are formed to overcome the additive manufacturing defects and material performance problems, At the same time, it has short processing time, effectively breaks through the bottleneck of metal additive manufacturing technology, and realizes high-quality and efficient additive manufacturing.Main business: research and development of high-performance component metal additive manufacturing equipment and on-line monitoring technologyApplication fields: national defense, military industry, aerospace and other fields
