Abstract: Diamond has extremely high hardness and excellent wear resistance. Diamond tools made with diamond as abrasive grains play an irreplaceable role in the efficient and precise processing of hard and brittle materials.However, with the popularization and application of new hard and brittle materials and the continuous improvement of modern precision processing requirements, there is an urgent need to develop diamond tools with complex shapes, refined structures, and high-end properties. Compared with traditional manufacturing technologies, laser additive manufacturing technology breaks through the structural design and manufacturing mode of traditional tools in principle, and can achieve the precise forming of diamond tools with complex shapes, small sizes, and ultra-thin thicknesses, which has attracted high attention from researchers at home and abroad. Retrieves the literature reports on laser additive manufacturing of diamond tools at home and abroad in recent years, and reviews the laser additive manufacturing technologies and processes of metal-based diamond tools and resin-based diamond tools.Finally, it points out the deficiencies in the current research status of laser additive manufacturing of diamond tools,and looks forward to the future research directions, providing a reference for the research and application of laser additive manufacturing of diamond tools, and promoting the innovation and development of superhard material tool manufacturing technologies.
