Restricted by technology and cost, 3D printing technology is difficult to replace mass assembly line production, but no need die, can be transformed directly from design to part fast and freely. It has been widely used in weapons and equipment design, complex and expensive parts manufacturing, and maintenance support. It is the key to future military equipment manufacturing technology innovation.At present, 3D printing has been widely used in Chinese military aircraft

3D printing technology simplifies manufacturing process of high-performance metal parts, thus greatly shortening the development and manufacturing cycle of military aircraft.

According to li daguang, a professor in the teaching and research department of military logistics and military science and technology equipment at the national defense university, it took at least 10 to 20 years to develop a new generation of fighter jets in the 1980s and 1990s,but with 3D printing, it will take at least three years.

3D printing technology can be used to optimize the structure of complex parts, thus reducing weight and increasing service life.

American F16s use 3D technology to make landing gear, with an average life of 2.5 times. Experts estimate that Titanium alloy forgings for F-22 could lose up to 40 percent of their weight if made using Chinese 3D printing technology.

As the only country in the world that has mastered the manufacturing and application of large laser-formed titanium alloy main bearing components, China's j-20, j-31, j-15, j-16 and other aircraft have widely used 3D printing technology. The rapid manufacturing of the y-20's fuselage/main landing gear connector and the large main load-bearing components is also done by 3D printing.

Facing the great challenge by 3D printing technology, metal injection molding technology’s advantage has been limited to mass production. Regarding design evaluation and prototype, 3D printing is much preferred. In future, the combination of metal injection molding technology and 3D printing technology will be the development trend in a long time.
