This paper presents preliminary research results of the influence of process parameters of the selective laser sintering technology (SLS) on the roundness and waviness parameters of cylindrical elements. The excessive values of these deviations impact on the further manufacturing process and reduce the functional properties of final products. The samples were designed in cylindrical shape and it were produced in the Laboratory of Unconventional Manufacturing Technology. The Formiga P100 machine was employed to build samples, using polyamide powder PA2200, which based on polyamide PA12. Due to the heterogeneity of the surface structure which is caused by layered nature of process, the samples were located on the virtual platform in three characteristic orientations. Measurement of the geometric deviations were performed on the Talyrond 365, which is located in the Laboratory for Computer-Based Measurement of Geometrical Quantities at the Department of Manufacturing Engineering and Metrology at Kielce University of Technology. The analysis of the research result showed that the building direction has a significant impact on the above mentioned parameters.
