Additive manufacturing technology of titanium alloy

Additive Manufacturing (AM), also known as "3D printing", is a digital manufacturing technology that enables mould-free forming of components, featuring integrated design and manufacturing, high machining accuracy, short processing cycles, and excellent physical and chemical properties. Additive manufacturing technology has been developing rapidly since the 1970s. Due to its great difference from traditional manufacturing technology, additive manufacturing technology has become a research hotspot in the industrial field and has been developing rapidly in many fields of modern industry.

With the rapid development of additive manufacturing technology, any single or polymetallic composite structure can be realized theoretically, which provides a new method for the manufacture of complex structural parts. The additive manufacturing technology of titanium alloy has solved the machining problem of precision structural parts and further expanded the application range of titanium alloy. With the rapid development of industrial society, the additive manufacturing technology of titanium alloy changes with each passing day. According to the different heat sources of the additive manufacturing technology, the additive manufacturing technology of titanium alloy can be divided into laser/electron beam additive manufacturing, fusion welding additive manufacturing and solid welding additive manufacturing. Domestic and foreign experts and scholars through different additive manufacturing technology means, optimize the process, stabilize the additive manufacturing process, reduce or avoid the additive manufacturing structure defects, so that the titanium alloy additive manufacturing technology towards the direction of green, efficient and stable development.
