摘　　要：目的:应用3D打印快速成型技术制备钛合金牙种植体并探讨其机械性能,为应用3D打印技术制备个性化牙种植体提供依据。方法:计算机上建立牙种植体及标准试件模型,应用3D打印激光快速成型技术制备钛合金牙种植体及标准试件,通过X射线衍射(XRD)、能量色散X射线光谱(EDS)分析3D打印钛合金种植体材料相组成,采用金相显微镜和扫描电镜观察其组织形貌,采用显微硬度测试仪和拉伸实验检测材料的机械性能。结果:3D打印钛合金种植体微观结构均匀。材料拉伸强度和屈服强度分别为(1 821.7±146.2)Mpa和(1 355.9±109.2)Mpa,延伸率为(31.3±1.8)%,维氏硬度为372.93~428.46HV,机械性能符合国家牙种植体材料医用标准。结论:3D打印快速成型技术制备的钛合金材料可满足牙种植体材料要求,有望在牙种植体制备和个性化即刻种植领域得到广泛应用。Objective： To prepare the titaniumaaloy（TC4） dental implant by novel 3D printing laser rapid prototyping method and analyze the mechanical properties of 3D printing TC4 material, and to provide foundation for the application of 3D printing technology in the preparation of dental implant.Methods： The digital models of dental implant and the test specimens were set up and the TC4 samples were prepared by 3D printing method. The phase composition and microstructures were observed by XRD,EDS, metaloscope and SEM, the mechanical properties of 3D printing TC4 material for dental implant were detected by microhardness tester and tensile experiment. Results： The microstructure of 3D printing TC4 material was uniform; the tensile strength, yield strength, and extensibility were （1 821.7±146.2） Mpa,（1 355.9±109.2） Mpa, and（31.3±1.8）%, respectively;the vikershardness was 372.93-428.46HV; the mechanical properties of 3D printing TC4 material met the national medical standards of dental implant material.Conclusion： The 3D printing TC4 material could meet the demanding of mechanical properties for dental implant material, and 3D printing technology is promising in dental implant preparation and immediate individual implantation.
