光硬化性シリカスラリーを用いたマルチマテリアル光造形

抄録

In recent years, multi-material stereolithography, which enables the fabrication of highly functional and high-definition 3-dimensional parts, has attracted much attention. However, most of the conventional systems have a problem that it is difficult to use highly viscous materials. In this study, we have improved the cleaning system of our lab-made multi-material stereolithography system using multiple droplets in order to completely clean high viscosity materials. Using this system, we succeeded in making 3D silica structures using highly viscous silica slurry. In addition, we used two types of silica slurries doped with two different metal ions, Eu and Cu, and created a multi-material silica glass structure without material contamination. This method is expected to be applied to various functional devices such as optical and microfluidic devices.
