Some time ago, the No. 705 Research Institute of China Shipbuilding Heavy Industry Co., Ltd. completed the first prototype of the new Direct Direct Sintering Rapid Prototyping Technology (DMLS) and became the fourth company in the world to master this technology. 3D printing of metal parts achieved a major breakthrough and successfully entered the international leading position. Nowadays, 3D printing technology is becoming more and more mature, and the scientific and technological achievements realized by 3D printing technology are more and more sophisticated, more and more complicated, and with the birth of 3D printing aerospace engine, it marks our technology A big step forward! Beijing Power Machinery Research Institute has successfully applied metal 3D printing technology to realize the trial production of some complex, critical and important parts of the engine, breaking through the bottleneck of “engine design is restricted by the processing levelâ€, marking the entry of China’s aerospace engine into the “fast laneâ€. . The 3D printing technology of metal materials is mainly based on metal powder, granules or wires as raw materials, pre-layered by CAD model, and the laser beam is used to melt the material and solidify to form a metal material additive manufacturing technology. Compared with metal processing technologies such as traditional lathes and CNC machine tools, this technology has the advantages of free mold free molding, fast processing speed, low production cost of small batch parts, strong ability to process complex shaped structures, and arbitrary composite manufacturing of various materials. It has aroused widespread concern from aerospace units at home and abroad. “The new generation of aerospace and aerospace engines have the characteristics of variable design and high frequency of repetition in the pre-research stage. This is very demanding for rapid manufacturing response. At the same time, in order to improve various engine performance indicators, the structure of parts and components is also becoming more and more In the complication, this has added a lot of difficulties to the trial production stage of the engine.†The head of process technology at the Beijing Institute of Power Machinery said that the introduction of metal 3D printing technology into the field of aerospace engine parts manufacturing can respond to rapid manufacturing needs. It is of great significance to improve China's engine design and manufacturing capabilities. Designed as a concenient solution for temporary storage and transferring slide.
