基于粉末的增材制造（AM）技术越来越受到关注，因为它实现了具有大自由度的任意三维结构的高速制造，这几乎是使用传统制造工具不可能实现的。在早期，AM被称为快速原型（RP），其仅仅针对主要由树脂材料制成的产品的试验原型。今天，由于热源、光学系统、原材料生产等方面的进步，AM的预期作用已经显著地转变为直接制造由从树脂到陶瓷、金属和金属间化合物的各种材料制成的最终或接近最终的产品。由于粉末增材制造是一种自下而上的制造方法，它为小批量生产各种产品提供了很大的优势;因此，量身定制的产品组合是增材制造的一个有力目标。本文综述了AM在骨科用功能性金属生物材料开发中的优势和可能性。医疗需要根据个人的病理条件和体质灵活地进行，因此，医疗设备的功能应该是可调的，这是AM的一大优势。
Powder-based additive manufacturing (AM) technology has increasingly attracted attention because it realizes fabrication of arbitral three-dimensional structures with a great degree of freedom at high speed, which is almost impossible using conventional manufacturing tools. In early times, AM was known as a rapid prototyping (RP) which merely aimed at a trial prototyping of products mainly from resin materials. Today, thanks to the progress in the heat source, optical system, raw material production, etc., the expected role of AM has dramatically changed into a direct fabrication of final or near-final products made from a variety of materials from resins to ceramics, metals, and intermetallic compounds. Because the powder-based AM is a bottom-up manufacturing method, it offers a big advantage for the small-lot production of a wide range of products; therefore, tailor-made product portfolio is a potent target of AM. In this review paper, the advantage and possibility of AM in the development of functional metallic biomaterials for orthopedic usage is described. Medical treatments need to be flexibly done in accordance with individual pathological conditions and constitutions, therefore, the function of a medical device should be tunable, which is quite a strength of AM.
