Micro-stereolithography is able to fabricate free-form 3D microstructures easily and rapidly by laminating of thin layers formed by cured resin. However, materials that can be used for this method are only photosensitive resin which has no electrical conductivity. So, we developed to mix metal powder which has superior electrical conductivity as the filler into the acrylic photosensitive resin. By applying the resin to micro-stereolithography, we could fabricate 3D microstructures with superior electrical conductivity. We investigate the lamination procedure of fabricating micro parts using the resin mixed with silver particles. As a result, cubic shape could be fabricated and the minimum layer thickness is 5μm.
