摘要
多孔金属有着优异的抗腐蚀性、生物相容性和与人骨相匹配的力学性能,并且内部有着高度互通的孔隙结构,可促进体液的传输和新骨组织的内长入,是人体理想的替代植入物。增材制造技术因其自身的精确性、快速性在金属多孔植入物中变得日益重要。简述了主流的两种增材制造技术在植入物制备中的应用、增材制造用金属植入物材料和多孔植入物的表面拓扑优化方法,并对其在金属多孔植入物中的应用前景进行了展望。
Porous metal has excellent corrosion resistance, biocompatibility and mechanical properties matched with human bone, and it has highly interconnected pore structure inside, which can promote the transmission of body fluids and the incorporation of new bone tissue, and it is an ideal substitute implant for human body. The additive manufacturing technology becomes increasingly important in porous metal implants due to its own accuracy and rapidity. The application of two mainstream additive manufacturing technologies in implant preparation, metal implant material used for dditive manufacturing and the surface topology optimization method of porous implants were briefly described, and their application prospects in the metal porous implants were prospected.
