摘　　要：三维打印(3DP)成型技术适合成型形状复杂、结构精细的个体化多孔医用生物植入材料,能满足不同患者的不同需求。本文应用3DP成型技术制备直径为25mm×20mm的多孔纯钛植入体生柸,于500℃真空脱粘后,在氩气保护下烧结至1 300℃,利用扫描电镜(SEM)观察其孔径大小介于50～150μm,其孔隙率、体积密度、维氏硬度、抗压强度及弹性模量测试结果分别为(44.26±2.43)%、(2.59±0.81)g/cm3、134.2～151.6、(61.2±3.2)MPa、(3.25±1.08)GPa。结果表明,3DP成型技术在制备个体化多孔纯钛植入体方面有着广阔的应用前景。Three-dimensional printing（3DP） forming technology can shape personalized porous implant material with complex shape and fine structure to meet the various needs of different patients.In this paper,the green parts of porous titanium implants with diameter 25mm×20mm were prepared using 3DP,and then debinded at 500℃ under vacuum.Finally they were sintered in the argon gas at 1 300℃.The pore sizes were observed,and they were between 50-150μm under SEM.The results of porosity,bulk density,Vickers hardness,compressive strength and elastic modulus were（44.26%±2.43）%,（2.59±0.81）g/cm3,134.2-151.6（61.2±3.2）MPa,（3.25±1.08）GPa,respectively.That shows excellent biomechanical compatibility.It is concluded that 3DP has wide application for fabrication of personalized porous titanium implant.
