7PM1-D-4 ディップ光ファイバープローブを用いたマイクロ光造形法の提案・実証(7PM1-D OS2 三次元の微細形状創成技術)

Abstract

Most of microstereolithography systems require a reservoir tank to supply a photopolymer. In addition, thin layers of photopolymer must be formed to make a 3-D structure via layer-by-layer process. Owing to these intrinsic properties, conventional microstereolithography systems need a lot of photopolymer to produce large-scale models. In this study, we intend to develop a novel microstereolithography system using an optical fiber. In this system, a laser beam emitted from the tip of the optical fiber is used to polymerize a photopolymer that kept between the optical fiber and a substrate. Since 3-D structures are fabricated using only a little photopolymer droplet, this system does not require a tank to keep the photopolymer. In addition, 3-D scanning of the tip of the optical fiber enables to add 3-D microstructures to the desired position on a substrate with small amount of photopolymer.
