摘　　要：近年来,人们利用增材制造这项高性能、高效率、低成本的高潜力技术制造出了许多传统工艺制造不出的复杂零件.但是,由于增材制造技术和扫描策略的不同,采用增材制造技术制备的样品在微观结构和力学性能上具有三维各向异性.文中通过对不同增材制造技术的特点进行对比,从而讨论其生产出的不同金属样品组织和性能的区别,通过对组织的分析来探索其性能上的差异,进一步了解样品的各向异性,并简要说明他们之间的差异.最后,根据目前的研究成果,提出了未来研究还需解决的问题.In recent years,manufacturing,a high-performance,high-efficiency,low-cost,high-potential technology,is used to produce many complex parts that cannot be produced by traditional processes.However,due to the difference in the scanning strategies of additive manufacturing technology,the three-dimensional parts prepared by additive manufacturing technology has three-dimensional anisotropy in the microstructure and mechanical properties.This study compares the characteristics of different additive manufacturing technologies and discusses the differences in the microstructure of different metallic parts produced by them.Finally,according to the current research,the problems need to be solved in future research are put forward.
