Long March 5B was outfitted with a new-generation maned spaceship test ship, and a portable cargo return cabin.
An “3D Printer” was also added to the new-generation, humanoid spacecraft test boat. China’s 3D printing experiments in space are the first of its kind. This also represents an international 3D printing trial for continuous fiber-reinforced, composite materials. How did it print the spaceship’s composite materials?
China developed a composite space 3D printing technology that could be carried onto the ship. These “3D printers” were installed by the researchers in the back cabin of the test boat. The continuous fiber Enhanced sampling of composite materials was completed by the system during flight. It also verified scientific experiments regarding 3D printing composite materials under microgravity conditions.
It’s well-known that composite materials made from continuous fiber reinforced are used as spacecraft materials at home and overseas. This research is on space 3D printing technology. Development of super-large orbital manufacturing structures is essential for long-term space station operation.
Composite materials consisting of continuously reinforced fibers are currently used to build spacecraft structures in the United States and around the world. These materials have high strength, low density, and great strength. This research is vital for long-term space station operation and future development of high-volume spacecraft structures. .
The Stereolithography 3D printer technology of Space Application Center of Chinese Academy of Sciences is utilized on-orbit to manufacture metal/ ceramic composite materials. It has micron-level precision.
Space 3D-printing research of China’s Space Application Center of Sciences. Reports indicate that the Long March 5B rocket placed China’s new-generation maneuverable spacecraft test ship in an orbit. This is a potential research area for China’s 3D-printing technology. Space Application Center of Chinese Academy of Sciences developed “On orbit fine forming experimental device”. This will enable space manufacturers to increase their manufacturing accuracy. Stereolithography is challenged by space weightlessness. An ordinary printing paste won’t hold its form in space weightlessness. Additionally, wall climbing can lead to liquid level fluctuations. Over 100 tests conducted under microgravity, at home as well as abroad, the rheological and internal behavior of the Slurry were determined. Its yield strength resists deformation, inhibites wall climbing, can restore good fluidity when subjected to greater shear forces and allows smooth 3D printing.
In 2018, 3D printing was successfully tested under microgravity by the Key Laboratory of Space Manufacturing Technology of Chinese Academy of Sciences. It’s believed that the CAS Key Laboratory of Space Manufacturing Technology SMT was established towards the end of 2017. This center is a scientific research unit that researches on “space-making technology.” In June 2018, scientists at the Key Laboratory of Space Manufacturing Technology of Chinese Academy of Sciences in Dubendorf in Switzerland successfully performed the first international stereolithography of clay materials in a microgravity atmosphere using European weightless airplanes. The test involved casting technology as well as form technology.

Space 3D printers: Their role and benefits Space 3D printers can be used to make manufacturing (that is, model files) from the Earth, and sent them by email to International Space Station. The process itself takes only a few days and is finished in about four hours. It is also worth the time and transportation savings that space 3D printing offers. Each part of the complex space station, base, and spacecraft systems is composed of multiple parts. Although the system strives for reliability, problems can still arise such as damage to parts and upgrades. Prefabricated parts can significantly increase launch costs. To use 3D printing in space, it is necessary to only bring raw materials along with light-weight printers into space. These will be used to create the desired parts quickly, lower the launch weight, increase efficiency and decrease costs. If humans have access to the resources they need on other planets in the future, then space-based “parts factories,” or space mining, will allow them to reduce launch weights and save space.
FDM melt Extrusion is used on NASA International Space Station, USA. Heat the nozzle until the polymer wire becomes liquid. It is then extruded through mechanical force. Layer by layer. NASA. NASA introduced the concept of “space manufacturing” in 2014 when it brought its first 3D printer to space. 3D printing in space requires a completely different working environment to that found on the Earth. While 3D printing can still be done on the ground, which relies heavily upon gravity, it is possible to deposit the heat-extruded plastic, metal, or other material by using a 3D printer layer by layer. You will need to adjust the speed of the centrifuge to help the machine run smoother under zero gravity. It’s easier to adapt 3D printing technology from the Earth to Mars, and Mars in microgravity.
