Abstract

Metal lamination manufacturing equipment and patient-specific implants that design and directly output implants suitable for patients by utilizing the medical image data of patients have been produced and used. The purpose of this study is to identify the mechanical characteristics of selective laser melting (SLM) and electron beam melting (EBM) 3D printer output methods of skull implants and to suggest a suitable output method for patient-specific skull implants. SLM and EBM samples were prepared in the hemispherical form with reference to commercial implants. Thereafter, the compressive strength and flange cantilever of the plates of the samples were examined; surface roughness and hardness were further evaluated. The EBM sample was found to have excellent strength and elasticity characteristics. As a result, it was judged that the sample prepared via EBM was suitable for skull implant preparation.
