    摘要:

    将激光金属直接成形技术应用于个性化钛合金假体的制造,能根据假体的三维模型直接制造出相应的零件,具有制造过程周期短和加工出的个性化假体力学性能好的优点。通过研究激光金属直接成形的曲率效应和倾斜角度对几何精度的影响,为激光金属直接成形的工艺模型设计准则提供参考,使假体成形件有较高的精度。制造出的个性化假体的力学性能和化学成分经过检测,均符合假体的相关国家和医药行业标准,有两例个性化钛合金假体已经成功应用于临床并取得良好的效果。

    Abstract:

    By applying laser metal direct forming technology into the manufacturing of the customized titanium implants, titanium implants can be directly formed according to their CAD model. This method has the advantage of short manufacturing cycle. Additionally, the customized titanium implants manufactured in this method have good mechanical properties. The influences of curvature effect and inclination angle on the geometric precision of laser metal direct forming parts were studied for the establishment of the model design criteria. Therefore,the formed titanium implant manufactured could achieve high precision. Both mechanical properties and chemical composition of the manufactured customized titanium implants comply with relevant national and pharmaceutical industry standard. Two cases of customized titanium implants manufactured by laser metal direct forming have been successfully used in clinical and have achieved good results.
