The Chongqing Institute of Green Intelligent Technology of the Chinese Academy of Sciences announced on April 18 that the first domestic space 3D printer jointly developed by the Institute and the Space Application Engineering Technology Center of the Chinese Academy of Sciences has successfully completed the parabolic weightless flight test in Bordeaux, France, capable of being in a micro-heavy environment. Complete 3D printing. According to Duan Xuanming, director of the 3D Printing Technology Research Center of the Chongqing Research Institute of the Chinese Academy of Sciences, the printer's largest component size is 200×130mm, which is more than twice the size of NASA's first space-in-orbit printer. In early March of this year, the printer conducted a parabolic weightless flight test in Bordeaux, France. A total of 93 printing tests were carried out in 3 days, realizing two kinds of materials such as plastic and composite materials, and three kinds of process parameters under weightlessness, overweight and normal gravity, and four kinds of models, such as microgravity printing, which successfully acquired the microgravity environment. The experimental data affected by the 3D printing process parameters laid the foundation for China's completion of the space station construction and later operation in 2020. Duan Xuanming introduced that space-based 3D printing manufacturing is an effective way to solve the space station maintenance support needs. At present, space station astronauts rely heavily on the supply of the ground. Almost all supplies in the space station require ground replenishment, especially some precision instruments. If astronauts can make the necessary experimental and maintenance tools and parts in a weightless environment, the flexibility of space station experiments and maintenance will be greatly improved, and the types, quantities and operating costs of spare parts in the space station will be reduced. It is understood that the space station needs at least half a year to wait for an earth supply, and 3D printing only takes 1-2 days to produce parts that need to be replaced. Duan Xuanming introduced that this printer is the third edition of their research and improvement. Through continuous research and development of design, motor and transmission equipment, and through weightless flight test, it proves that the printer is inclined and inverted on the earth. It can be printed without gravity, and the printing effect is equivalent to foreign level. Duan Xuanming said that he hopes that this achievement can be applied to China's space station.
