Abstract: Due to the high hardness and excellent wear resistance, diamond is widely used in the preparation of cutting and other machining tools . As compared to traditional manufacturing technology, additive manufacturing can fundamentally solve the problems of innovative design and efficient fabrication for complex structural components, and is a potential effective method for preparation of high-performance diamond tool. This article introduces the basic principles and characteristics of major additive manufacturing technologies such as Selective Laser Sintering (SLS), Selective Laser Melting (SLM), Stereo Lightgrapy Apparatus (SLA), Direct Ink Writing (DIW) and Fused Deposition Modeling (FDM). The applicability of different additive manufacturing technologies in the preparation of diamond grinding wheels, diamond drill bits and diamond saw blade tools as well as the performance of manufactured tool are analyzed. Finally, the typical problem in the deposition process of additive manufactured diamond tools and the corresponding solution idea are summarized and provided, respectively.
