The level of civil aerospace manufacturing is not only a yardstick to measure a country's scientific and technological strength, but also directly reflects the development level of human technology. The products are composed of millions of parts, with a wide variety and complex structure, which have high requirements for stability, safety, lightweight and refinement. Based on this, there are very high process requirements and quality standards for the design and manufacture of parts in all links. Metal 3D printing technology can fully meet the needs in the aspects of complex structure forming, lightweight design, shortening production cycle and so on. it has become the backbone of promoting the rapid development of civil aerospace manufacturing industry.
