3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files, using powdery metal or plastic and other adhesive materials, and constructed by layer-by-layer printing Object technology.
With the advancement of 3D printing technology and continuous product innovation, the global 3D printing market has expanded rapidly in recent years. At present, the global 3D printing technology has been developed to ceramic 3D printing, polymer 3D printing, metal 3D printing and biological 3D printing, etc., and has been applied in various fields. The United States is the main competitive area of the 3D printing industry, with a market share of more than 40%, followed by Japan, Germany, and China ranked fourth. In 2018, China's 3D printing market reached 2.36 billion yuan, a year-on-year increase of nearly 42%. With the corresponding maturity of China's 3D printing technology, demand in the aerospace, automotive and other industries will continue to increase.
