摘要:: 金属零件3D打印技术作为整个3D打印体系中最为前沿和最巨潜力的技术，是目前先进制造技术的重要发展方向。随着科技发展对材料的不断需求，利用快速成型技术直接制造金属功能零件将会成为该技术的主要发展方向。3D打印技术正在快速改变着我们传统的生产方式和生活方式。未来，以数字化、网络化、个性化、定制化为特点的3D打印制造技术被外界认为将推动第三次工业革命。激光工程化净成形技术（Laser Engineered Net Shaping，LENS），激光选区熔化技术（Selective laser melting，SLM）及电子束熔化技术（Electron Beam Melting，EBM）三种技术是金属零件3D 打印技术的典型代表。本文首先以这三种技术为例介绍了金属3D打印技术，包括基本的技术原理，其次介绍了金属3D打印技术的应用领域，最后对它们的发展进行了展望。

Abstract:: Manufacturing of Metal Parts by 3D Printing Technology, as the greatest advanced and potential technology, presents the most important direction of Modern Advanced Manufacturing Technologies. With the development of science and technology constantly demand for materials, utilizing the Rapid Proto-typing Technology producing metal functional parts directly will be the main research directions. 3D printing technology is rapidly changing our traditional mode of production and way of life. 3D printing manufacturing technology, which is networked and personalized, will drive the third industrial revolution. Laser Engineered Net Shaping (LENS), Selective laser melting (SLM) and Electron Beam Melting (EBM) are the typical representative of the metal parts 3D printing technology. Based on the three types of technologies, this paper gave an overview introduction on metal 3D printing technologies, which include the basic constitution of equipments and fabricating principles. Then, the application fields of metal 3D printing technologies were introduced. At last, the development prospects of them were discussed.
