This paper describe a new application of stereolithography using LCD mask. Rapid Prototyping (RP) has been developed as the key manufacturing process for fabricating solid model from a computer aided design (CAD). In this paper, we propose a new RP process for micro manufacturing, namely stereolithography using liquid crystal display (LCD) mask. The stereolithography using LCD mask employs the mask method for fabricating 3-dimensional object precisely. This process is characterized by the exposing method and the nonlaminate 3-D constructing process. Several experiments were performed to verify the proposed method. Both a micro gear with a tooth width of about 80 E m and pyramidal shape 1.5mm in height can be fabricated in a few seconds without lamination.
