The purpose of this paper is to develop a STL viewer implementation for RP system. The STL which is a standard specification for exchanging data of RP, is simple and easy for transforming 3D data to 2D slicing data. But, STL does not have the information of coordinate origin for displaying 3D facet data. And STL has problems which is called facet overlap, lack of accuracy measure, and errors of normal vector value. We solved these problems using scaling, linear transformation, verifier and error corrector. We tested and verified that our STL viewer has a good property in views of stability, extension, and efficiency.
