Metallic additive manufacturing, a process by which metal structures are created in a layered fashion, is poised to revolutionize orthopaedic implants and instruments. It allows for the design and manufacture of devices, which not only macroscopically more closely match patient-specific anatomy but also have improved microscopic detail for more rapid and durable host integration. In addition, additive manufacturing-designed implants have improved biomechanical properties and fixation systems allowing use in areas where current implants are not well suited. This review provides an overview of the technology and both its current and future use in orthopaedic surgery.
金属增材制造技术，一种通过分层方式制造金属结构的工艺，有望彻底改变矫形植入物和器械。它可以设计和制造不仅在宏观上更接近患者特定解剖结构，而且具有改进的微观细节，从而更快、更持久地与宿主整合的设备。此外，增材制造设计的植入物具有改进的生物力学特性和固定系统，使其可以在当前植入物不适用的区域使用。本文综述了该技术的现状及其在矫形外科中的应用。
