초록

This study presents experimental information on human manikin optimal orientation for nonprofessional 3D printer users. We displayed the required number of filaments with a 3D parametric graph, in which the rotational angles with respect to the global X- and Y-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 in our previous study. The dissected parts were converted to G-codes using slicing software to determine the optimal orientation that minimizes the amount of support structure. The final parametric graph verified that the manikin of 1/10 scale full body had the lowest support structure when it was on the back of the 3D printer bed. The other scales had the optimal orientation when the cylindrical center of each part of the axis coincided with the global Z-axis. The 1/1 manikin was converted into a shell structure, and the same procedure was repeated. Finally, an actual PLA-based human manikin was 3D printed using the optimal orientation information.
