Laser Metal Direct Forming of the Customized Titanium Implants

Laser metal direct forming technology was applied to manufacture customized titanium implants, and then titanium implants can be directly formed according to their CAD models. This method possesses a 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 could achieve high precision. Both mechanical properties and chemical composition of the manufactured customized titanium implants comply with relevant national and pharmaceutical industry standards. Two cases of customized titanium implants manufactured by laser metal direct forming have been successfully applied in clinical and have achieved good results.
