制备钛合金人工骨中的3D打印
|
Abstract:
3D打印作为近几十年快速发展起来的一种新型的制造工艺，因其快速成型、无模制造和个性化制造等优势被广泛运用于医疗领域。该制备技术将使医用钛合金假体更便宜、更实用，还能制造传统工艺难以制造的结构。但其制备的医用材料是否满足使用要求一直在被人们质疑和研究。本文主要针对近年来3D打印的TC4钛合金(Ti-6Al-4V)人工骨的可行性和近年来使用于临床的3D打印医用TC4钛合金人工骨治疗效果的研究进行综述，综述的内容主要集中在3D打印产品的质量、机械性能、生物相容性、生物安全性、生物毒性、耐腐蚀性和表面改性等，旨在为相关研究的开展提供一定的参考。
As a new manufacturing process rapidly developed in recent decades, 3D printing is widely used in the medical field because of its advantages of rapid molding, mold-free manufacturing and personalized manufacturing, etc. The preparation technique will make the medical titanium alloy prosthesis cheaper, more practical, and can manufacture structures that are difficult to manufacture by conventional processes. However, whether the medical materials prepared meet the use requirements has been questioned and studied. This paper mainly reviews the feasibility of 3D printed TC4 titanium alloy (Ti-6Al-4V) artificial bone and the therapeutic effect of 3D printed medical TC4 titanium alloy in recent years, focusing on the quality, mechanical properties, biocompatibility, biosafety, biotoxicity, corrosion resistance and surface modification of 3D printed products, aiming to provide some reference for related research.
