The material of parts produced by laser stereolithography is a photopolymer. The photopolymer parts must be reinforced by particles or short fibers to increase the mechanical strength of the parts. The purpose of this research work is to reinforce the photopolymer part along thickness direction. Carbon fiber was selected as the fiber because the carbon fiber has high tensile strength. Static electricity was used for orientation of the carbon fiber along thickness direction. The orientation conditions for example, applying voltage between electrode plates, length of carbon fiber and orientation repetition time were examined. Orientation of carbon fiber was possible under a wide range of conditions.
