Surface Roughness Model for Components Created by Stereolithography Method
Rapid prototyping (RP) can fabricate complex 3D physical models without geometric limitations. The surface of the RP processed components is excessively rough (called stair-step effect) and depends on several parameters such as thickness of layer, position on the platform, etc. This paper presents several surface roughness models and results of experimental research.
