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。3D打印技术以其丰富的加工方式在医用钛合金方面应用优势逐渐凸显。本文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。Titanium and its alloys have been used as one of the most important biomaterials due to their high strength,good corrosion resistance and excellent biocompatibility.Casting is the most important way to produce implantable products such as spinal cage and knee implants before.However,this method is outdated to fit new biomaterials requirement such as personalized implants and precision medicine cure.The advantages of 3D printing technology in medical titanium alloys are gradually highlighted due to its abundant processing methods.This paper mainly discussed the development of 3D printing technology on bio-used titanium and its alloys,and especially focused on porous titanium implants printing.The technical barrier of current 3D printing for bio-used titanium alloys was analyzed.Suggestions for further development on biomaterials 3D printing industry were also given at the end of the paper.
