摘　　要：金刚石具有较高硬度和良好的耐磨性,是制备切削等加工工具的理想材料。相比传统制造技术,增材制造技术能从根本上解决复杂结构件创新设计和高效成型的问题,是高性能金刚石工具制造的潜在有效方法。本文介绍了选择性激光烧结、选择性激光熔化、立体光固化、浆料直写成型及熔融沉积成型烧结等主流增材制造技术的基本原理和特点,分析了不同增材制造技术在制备金刚石砂轮、金刚石钻头和金刚石锯片工具方面的适用性及工具服役性能,总结了增材制造金刚石工具在成型过程中存在的典型问题并给出了相应的解决思路。Due to the high hardness and excellent wear resistance,the diamond is widely used in the preparation of cutting and other machining tools.Compared to the traditional manufacturing technology,the additive manufacturing can fundamentally solve the problems of innovative design and efficient fabrication for the complex structural components,which is known as a potential effective method for the preparation of high-performance diamond tools.The basic principles and characteristics of the major additive manufacturing technologies were introduced in this paper,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 and performance of the manufactured tools prepared by additive manufacturing were analyzed,such as diamond grinding wheels,diamond drill bits,and diamond saw blade tools.Finally,the typical problems and the corresponding solutions in the forming process of additive manufactured diamond tools were summarized and provided,respectively.
