Abstract:
In this paper, the current research hotspots and related research progress of laser additive manufacturing technology were analyzed from the aspects of material, technology, equipment, and application. And the main development directions in the future were combed. In terms of materials and processes, the related research was mainly focused on the laser additive manufacturing of lightweight alloy and high-value alloy. From the point of view of forming equipment, large-scale equipment, high-speed, and composite processing were the main development direction in the future, while the application was it mainly focuses on the laser additive manufacturing of high performance, high value parts, and biological implants. Generally speaking, high quality, high performance, and high efficiency will be the focus of laser additive manufacturing in the future.
