my country's first space 3D printer officially exposed
Introduction: Duan Xuanming, deputy director of the Intelligent Manufacturing Technology and Wood Research Institute of the Chongqing Research Institute of the Chinese Academy of Sciences, and director of the 3D Printing Technology and Wood Research Center, introduced that after two years of hard work, the Institute and the Space Application Center have developed my country's first space 3D printer.
OFweek3D Printing Network News The Chongqing Research Institute of the Chinese Academy of Sciences and the Space Application Center of the Chinese Academy of Sciences recently jointly developed my country's first space 3D printer, and recently completed a parabolic weightless flight test in Bordeaux, France. The size of the large parts that can be printed exceeds that of the National Aeronautics and Space Administration (NASA) Printed size of an upgraded 3D printer shipped to the International Space Station on March 26.
The reporter saw at the Chongqing Research Institute of the Chinese Academy of Sciences that a 3D printer the size of a safe prints different types of parts, including wrenches, nuts, connecting rods, etc. This spatial 3D printer works fine no matter how tilted it is.
Duan Xuanming, deputy director of the Intelligent Manufacturing Technology and Wood Research Institute of the Chongqing Research Institute of the Chinese Academy of Sciences and director of the 3D Printing Technology and Wood Research Center, introduced that after two years of hard work, the Institute and the Space Application Center have developed my country's first space 3D printer, which can print large parts and components. The size reaches 200×130mm, which is more than twice the printing size of NASA’s first space on-orbit printer, and exceeds the printing size of the upgraded 3D printer that NASA shipped to the International Space Station on March 26 this year.

"We completed the parabolic weightlessness flight test in Bordeaux, France. Through 93 weightlessness tests, we verified the key technologies and processes of 3D printing equipment in a microgravity environment, and realized two materials, plastic and composite materials, as well as weightless, overweight and normal The microgravity printing of 4 models of 3 types of gravity process parameters has obtained experimental data on the influence of the microgravity environment on the 3D printing process parameters, laying a foundation for my country to complete the construction of the space station and post-operation in 2020."
On-orbit 3D printing manufacturing is an effective way to solve the maintenance and support needs of the space station, and is a necessary guarantee for the completion of future deep space exploration missions.
The reporter learned that before there is no space for on-orbit 3D printing manufacturing technology, the space station needs to prepare and store spare parts for maintenance and replacement. If there is a lack of spare parts, it can only be transported to the space station by a cargo spacecraft, which takes a long time and costs a lot.
Duan Xuanming said that the printing speed of space 3D printing manufacturing technology is 10-30 mm/s, which can print parts that need to be replaced within one to two days, and is suitable for most parts, operating in the space station, deep space It plays an indispensable role in tasks such as detection, and can easily and quickly help astronauts make necessary experimental and maintenance tools and parts in a weightless environment, greatly improving the flexibility of space station experiments and the timeliness of maintenance, reducing The types, quantities and operating costs of space station spare parts reduce the space station's dependence on ground supplies.
