Streszczenie / Summary:

Stereolithography is an additive rapid prototyping method. This method is based on the principle
of solidifying a liquid photopolymer (resin) by laser radiation. Models obtained with this
method are characterized by a specific surface structure called “stairstep effect”. It causes that, the
surface should be processed by additional finishing (postprocessing). To minimize the additional
machining process, the model should be set in the relation to incremental layers so that the roughness
of significant surfaces is optimal. In order to optimize this process, surface roughness models
of components are created using Stereolithography method. This paper presents the various models
of surface roughness described in the literature and also compares the consistency of mapping
models with the actual surface.
