    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.
