Abstract

3D printing was adopted to create a miniature human manikin. One of the disadvantages of 3D printing, especially fused deposition modeling type, is the need for a support structure for overhangs. The support structure can be waste of raw filament in a way, and also harms the surface smoothness of the final printed product. To minimize the amount of support structure, human body parts were dissected into cone-shaped segments by automatically finding bone and surface feature points. A commercial 3D printer was used and the printed manikins with and without body segmentation technique were compared quantitatively. Our cone-shaped segmentation-based printing scheme showed dramatically less amount of support structure and more smooth surfaces on most segments, except for non-cube shapes such as the head, hands, and feet.
