3D printing began to emerge from the 1990s, its development is based on high energy hot melt cladding technology and rapid prototyping technology, compared with the traditional technology of manufacturing, not after all kinds of knives cutting and processing of a variety of complex process and greatly reduce the processing time, at the same time for complex components, its processing and manufacturing precision is higher.

Titanium alloy parts made with 3D printing technology have very high strength and precise size, and their mechanical properties are superior to forging process. Because of its good biocompatibility and excellent mechanical properties, titanium alloy is mainly used in biomedical materials, aerospace, precision instruments and so on.
