3D Printing of Biomedical Titanium Alloy- A Review

摘要:

钛合金拥有较高的比强度、较好的耐蚀性能与生物相容性,其在医用植入物的应用市场前景十分引人关注。但传统医用钛合金植入物常采取铸造的生产方式,产品种类单一,无法满足“精准医疗”的诊疗目标。随着3D打印技术的发展,其丰富的加工方式在医用钛合金3D打印方面的应用优势逐渐凸显。本文将介绍多孔医用钛合金的发展历史及3D打印钛合金的制造现状,分析现有3D打印医用钛合金的技术壁垒,并为未来3D打印医用钛合金的发展方向提供建议。

Abstract:

Titanium and its alloys are wildly used in aerospace, chemical and biomaterials industries since its high strengths, good corrosion resistance and excellent biocompatibility. For titanium, which has been used as one of the most important biomaterials, the casting method is the most important way to produce implantable products such as spinal cage and knee implants before. While, this method is outdated to fit new biomaterials requirement such as personalized implants and precision medicine cure. With the development of the 3D printing technology, producing titanium implants by using 3D printer is becoming more and more popular and important. This paper will mainly discuss the development of 3D printing technology on bio-used titanium and its alloy, and especially focus on porous titanium implants printing. Suggestions for further development on biomaterials 3D printing industry will also be given at the end of the paper.
