Abstract

A major problem in laser beam melting is to post-process the complex surfaces. The objective of this research was to investigate the influence of three combined post-processing methods on customized implants manufactured by selective laser melting, focusing on complex contact surfaces between the parts and support structures. These anatomical contact shapes are the most difficult areas to be post-processed. The results showed that the roughness is reduced, the obtained surfaces are homogenous, and deviations between ±0.12mm could be expected. This study provides cases references for designing, directly manufacturing by Nd:YAG solid laser and post-processing of medical implants made from titanium powder..
