Three-dimensional (3D) printing technology has received great attention in the past decades in both academia and industry because of its advantages such as customized fabrication, low manufacturing cost, unprecedented capability for complex geometry, and short fabrication period. 3D printing of metals with controllable structures represents a state-of-the-art technology that enables the development of metallic implants for biomedical applications. This review discusses currently existing 3D printing techniques and their applications in developing metallic medical implants and devices. Perspective about the current challenges and future directions for development of this technology is also presented.

在过去几十年中，三维（3D）打印技术因其具有定制制造、制造成本低、具备前所未有的复杂几何形状制造能力以及制造周期短等优势，在学术界和工业界都备受关注。具有可控结构的金属3D打印代表了一种先进技术，能够推动用于生物医学应用的金属植入物的开发。本文综述了当前现有的3D打印技术及其在开发金属医疗植入物和器械方面的应用。同时还阐述了对该技术当前面临的挑战和未来发展方向的展望。
