Abstract As a “green and lightweight metallic structure material”, magnesium alloy has become a necessary choice to realize lightweight, complex and personalized structure manufacturing. In order to meet the requirements of high-end equipment on the high-performance components and break the barriers of traditional manufacturing technology, laser manufacturing technology of high flexibility, high cleanliness and high precision is gradually adopted to achieve complex and personalized structures. Thereinto, laser cutting, laser welding, laser surface modification and laser additive manufacturing of magnesium alloy are the currently main developing directions of laser manufacturing technology. Therefore, the basic principles, research focus and related research progress of different laser manufacturing technologies are introduced respectively. The development of laser manufacturing technology of magnesium alloy is summarized. Furthermore, multi-scale tools such as real-time monitoring are proposed with the goal of “reducing shape and increasing property”.
