Significance of China's First Completion of 3D Printing in Space.

China's space industry is booming, and many projects have been successful, laying the foundation for China's space industry. Recently, China's first space 3D printing was successfully completed? So what is the meaning and function? Then let's reveal the knowledge of constellations for everyone. China's first space 3D printing was successfully completed. A new generation of manned spacecraft test ship has installed a 3D printer. This is the first space 3D printing experiment in China, and it is also the first time in the world to carry out the 3D printing experiment of continuous fiber reinforced composites in space. During the flight, the system independently completed the sample printing of continuous fiber reinforced composites, and verified the scientific experimental goal of 3D printing of composites in microgravity environment. Look at this printer. What is printed on the spaceship? It is reported that this test ship is equipped with a composite space 3D printing system independently developed by China. The researchers installed this 3D printer in the return cabin of the test ship. During the flight, the system independently completed the printing of continuous fiber reinforced composites, and verified the scientific experimental goal of 3D printing of composites in microgravity environment. It is understood that continuous fiber reinforced composites are the main materials of spacecraft structures at home and abroad, with low density and high strength. The research on 3D printing technology of composite materials is of great significance to the long-term on-orbit operation of space station and the future on-orbit manufacturing development of space super-large structures. The first goal is to support the long-term manned operation and maintenance of the space station in orbit. The second goal is to support the on-orbit expansion of our space station. The role and advantages of 3D printing in space Generally speaking, when the International Space Station lacks some tools or components, astronauts have to spend weeks or even months waiting for ground supplies. With the space 3D printer, technicians can set up the manufacturing program (i.e. design model files) of items on the earth, and then send them to the International Space Station by e-mail. The whole process took less than a week. The actual printing time is only about 4 hours. In addition to the time cost, the transportation cost saved by space 3D printing is also considerable. The system of space station, base or complex spacecraft consists of many parts. Although it strives to be reliable in construction, it still faces problems such as parts damage and system upgrade. If you carry a large number of prefabricated parts into space, it will greatly increase the high launch cost. If space 3D printing technology is adopted, only raw materials and light printers need to be brought into space, and the required parts can be manufactured locally, so as to minimize the launching weight and improve work efficiency. In the future, when humans can mine raw materials from the surface of other planets, they can also set up parts factories in space to further reduce the launching weight of spacecraft and save space.
