Metal 3D printing technology is a "transformative" integrated advanced manufacturing technology of "preparation of high-performance materials and near-net-shape of metal parts". , it takes into account the rapid manufacture of complex shapes and high-performance metal components, and creates an important technical approach for the rapid research and development and innovative design of new products, thereby achieving lightweight, high-performance and low-cost product structures. Metal 3D printing can be directly used for aviation and aerospace functional structural parts, and can be used for structural verification, functional testing, batch direct application, etc. It can be shaped and manufactured according to user design requirements. Aerospace, automotive, precision instruments and other fields. At the same time, metal 3D printing can also be used for high-performance repair and remanufacturing of metal parts, realizing the full-life manufacturing and guarantee of high-performance metal parts.

There are many kinds of metal 3D printing materials, including titanium alloys, nickel-based superalloys, aluminum alloys, stainless steels, etc., which have broad application prospects in high-tech related fields such as aerospace, biomedicine, and power energy.
