(1) Aerospace industry. Another advantage of parts manufactured by 3D printing is that the parts manufactured can be lighter and help reduce fuel consumption for aircraft. Using 3D printing to make part model is more flexible and economical than traditional die manufacturing.
(2) Medical industry. Everyone's body structure is different, and it must be completely personalized customization. Three-dimensional printing technology can "tailor-made" organs for patients needing organ transplantation without fear of rejection.
(3) Architectural design industry: In the construction industry, 3D printers have been gradually used to print building models. This method is fast, low-cost, environmentally friendly and exquisite.
(4) Military field. For example, China's first fighter J-15, stealth fighter J-20 and other large-scale use of 3D printing technology. The U.S. military has used 3D printing technology to assist in the manufacture of missile ignition models, and 3D printing technology has been used in the manufacture of engine and military satellite parts.
