On the 5th of this month, China’s new generation manned spacecraft test ship was carried on the Long March 5 B carrier rocket, which successfully flew for the first time, and a “3D printer” was also carried on the ship.

This is the first space 3D printing experiment in China and the first 3D printing experiment of continuous fiber reinforced composites in space in the world,

China successfully completed the first space “3D printing”

There are two objects printed this time, one is the honeycomb structure (representing the lightweight structure of spacecraft), and the other is the CASC (China Aerospace Science and Technology Corporation) logo.

The researchers installed the “composite space 3D printing system” independently developed by China in the return cabin of the test ship. 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.

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 space 3D printing technology of composites is of great significance for the long-term on orbit operation of the future space station and the development of on orbit manufacturing of space super large structures.

Qi Junfeng, head of composite space 3D printing system of 529 plant of the Fifth Academy of Aerospace Science and Technology Group:

The first objective is to support the long-term manned operation and maintenance of the space station in orbit. If we have the ability to make things in the space station, we can realize on-demand manufacturing; The second goal is to support the on orbit expansion of our space station.
