인체 마네킨 조각의 최적 3D 프린팅 출력 배향 정보에 대한 정량적 분석

Abstract

This study presents experimental information on human manikin optimal orientationfor nonprofessional 3D printer users. We displayed the required number of filamentswith a 3D parametric graph, in which the rotational angles with respect to the global XandY-axes were the parameters. Three scales of human manikin data, including 1/1, 1/4,and 1/10, were prepared and automatically dissected using the algorithm developed inour previous study. The dissected parts were converted to G-codes using slicing softwareto determine the optimal orientation that minimizes the amount of support structure. Thefinal parametric graph verified that the manikin of 1/10 scale full body had the lowest supportstructure when it was on the back of the 3D printer bed. The other scales had the optimalorientation when the cylindrical center of each part of the axis coincided with theglobal Z-axis. The 1/1 manikin was converted into a shell structure, and the same procedurewas repeated. Finally, an actual PLA-based human manikin was 3D printed using theoptimal orientation information.
