With the continuous development of 3D printing technology, countries all over the world pay more attention to it and try to maximize its value in new fields! At 9:41 on September 25, 2015, with the huge roar, China’s first solid rocket, Long March, vacated from the Jiuquan Satellite Launch Center and carried four satellites into space.
One of the satellites, named "Pujiang No. 1", flew over the Huangpu River at 19:48 on September 26. The "Pujiang No. 1" satellite is different in that it uses 3D printed parts for the first time. The "Pujiang No.1" satellite was developed by Shanghai Aerospace Technology Research Institute of China Aerospace Science and Technology Corporation. It can realize fast and convenient comprehensive information service customized for users. It can be widely used in environmental monitoring, land resources survey, emergency search and rescue, etc. .
The 3D printing component of the Pujiang No. 1 satellite equipment is a titanium alloy antenna, which is the first in China. It takes about 4 months to make such a titanium alloy antenna in the traditional process. It took only 3 days to use the antenna made by the 3D printing process! A full 40 times gap! Among them, in the past three days, printing was completed in one day, and performance testing was carried out in two days. In addition, the cost of 3D printing has also been reduced a lot, so the advantages of these two points make them choose 3D printing technology to complete the manufacture of antenna components.
In the end, the 3D printed titanium alloy antenna passed the test perfectly, and all performance indexes were not shrunk. It is believed that with the continuous rapid development of 3D printing technology, similar applications will appear more and more, and more vigorously promote the continuous advancement of China's aerospace industry!
