EN The orientation of the sample during selective laser sintering (SLS) process is one of the factors that affect quality of the final product made from the AlSi10Mg powder. Most of the properties of AlSi10Mg bulk fabricated by SLS are strongly related to porosity, therefore one of the stages of quality inspection should enable for quick and precise analysis of the porosity without destruction the manufactured part. The paper shows that an effective tool in this area is computed microtomography. The presented methodology enabled not only the detection and visualization of pores in the whole volume of the samples, but, above all, allows for a full quantitative analysis, which included description of such features as: number, volume, shape and arrangement of the pores.
