원뿔형 인체분할을 이용한 용융 적층 방식 소형 인체 마네킨 3D 프린팅의 지지 구조 최소화

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.
