3D Printer로 제작된 인공뼈 구조에 대한 기계적 특성에 관한 연구

Abstract

The structure of the femur bone was analyzed. Moreover, the mechanical strength of the bone wasdetermined by considering two parameters, namely, the outer wall thickness and inner filling density torealize the 3D printing of a cortical bone and spongy bone by using a fused deposition modeling type 3Dprinter and ABS material. A basic experiment was conducted to evaluate the variation trend in themechanical strength of the test specimens with the change in the parameters. Based on the results, theparameters corresponding to the highest mechanical strength were selected and applied to the artificial bone,and the mechanical strength of the artificial bones was examined under a load. Moreover, we proposed anapproximation method for the 3D printing parameters to enable the comparison of the actual bones andartificial bones in terms of the strength and weight.
