Evaluation of the influence of selected parameters of Selective Laser Sintering technology on surface topography

The paper presents the preliminary research results of studies of the influence of basic technological parameters of the additive technology, Selective Laser Sintering (SLS), on the quality of geometric surface texture. Microstructural studies included the determination of two-dimensional as well as three-dimensional parameters of surface texture. The study includes the influence of technological parameters such as the orientation of the models on the virtual building platform, the energy density transmitted to the sintered powder layer and the building layer thickness. The results confirm that the above mentioned parameters have a significant influence on the geometrical surface texture. The most favorable variants of the location of the models on the building platform, the value of layer thickness and energy density applied to sintered powder were determined. (paper)
