적층 제조 방식으로 제조된 비골 금속판의 기계적 성능평가

In this study, the mechanical performance of a metal plate manufactured via 3D printing and machining was evaluated. This study aimed to identify the mechanical characteristics of selective laser melting (SLM) and electron beam melting (EBM) 3D printer output methods of fibula plate implants. SLM and EBM samples were prepared in the hemispherical form with a reference to commercial implants. We conducted static and dynamic four-point bending tests, and the results of these tests indicated good and poor performances, respectively, of the plate manufactured via 3D printing. Although satisfactory results were obtained in terms of static hardness of the plate manufactured via 3D printing, poor results were obtained under the condition of repeated loading. Thus, heat treatment is required for the plate design to be compatible with 3D printing-manufacturing with sufficient endurance for repeated loading. KCI Citation Count: 0
