Rapid prototyping apparatuses are widely used to create 3-dimensional models for industrial and medical applications. A stereolithography in which photosensitive resin is cured by laminating thin layers one by one has an issue of taking long time to fabricate a 3D model. In this research, a new stereolithography which uses multi laser beam to fabricate a 3D model is proposed. In this method, concentrating multi beams enhances the beam intensity to cure photopolymer at the beam-crossing point. This article describes the capability of this method. The property of the photopotymer was examined for realizing this method, and a fine columnar rod was successfully fabricated by scanning two beams at a position of beam-crossing.
