Study on Micro Stereolithography using Micro Lens Array

Abstract

Stereo lithography using conventional methods lacks the ability of fabricating simultaneous bulk parts. In most cases this is due to the fact that there is only one light source, e.g. a laser. Meanwhile, using multiple light sources for multi–point projection is expensive. In this experiment, we used a projector with digital mirror device (DMD) and micro lens arrays to simultaneously produce multiple micro SL parts. We established a multi–point fabrication method using micro lens arrays.
