“…It is deployed in several aeronautical, medicinal, automotive, and marine applications [4][5][6][7]. Using a laser as an energy source, laser additive manufacturing is a non-equilibrium metallurgical process involving a variety of complicated material metallurgy and physical and thermal coupling phenomena [8][9][10]. Surface defects such as porosity, spheroidization, unmelting, delamination, and fractures are prevalent, reducing the surface quality of produced components and reducing the mechanical properties, such as fatigue strength [11].…”

Due to the unparalleled benefits of traditional processing techniques, additive manufacturing technology has experienced rapid development and continues to expand its applications. However, as industrial standards advance, the pressing needs for high precision, high performance, and high efficiency in the manufacturing sector have emerged as critical bottlenecks hindering the technology’s progress. Single-laser additive manufacturing methods are insufficient to meet these demands. This review presents a comprehensive exploration of metal hybrid laser additive manufacturing technology, encompassing various aspects, such as multi-process hybrid laser additive manufacturing, additive–subtractive hybrid manufacturing, multi-energy hybrid additive manufacturing, and multi-material hybrid additive manufacturing. Through a thorough examination of the principles of laser additive manufacturing technology and the concept of hybrid manufacturing, this paper investigates in depth the notable advantages of hybrid laser additive manufacturing technology. It provides valuable insights and recommendations to guide the development and research of innovative machining technologies.

“…7 Bulges can increase the surface roughness of components and reduce the density and mechanical properties of components. 8 Also, holes in parts may be the starting point of failure, which can reduce the fatigue life of samples. 9 Due to the inhomogeneity of the metal structure and obvious anisotropy, 10 the structure and defect characteristics of metal AM components are also different from those of traditional process parts; while the main defect types and distribution characteristics are similar to those of traditional parts.…”
