? 2022 Elsevier LtdThis research examined the surface and internal structure of lattice samples with the use of computed tomography. The CAD system PTC Creo Parametric 8 was used to create a 3D model of a lattice structure. For research within this paper, two samples of ABS building material were produced with the use of FDM technology. One of them was destructively tested, i.e., deformed by pressure. The untested sample contained, in addition to base material, P400SR supporting material while the tested sample only contained ABS construction material. Individual samples were subjected to microCT scanning to perform samples' analysis of dimensional and shape characteristics and their porosity. The paper describes the procedure and methodology of individual problem-solving steps. Our basic requirement was to determine surface for software reconstruction as it affects all analyzes being performed. Since the unloaded sample also contains support material, the surface area for the base material only had to be determined and support material, while reconstructing the sample, be removed. Due to higher support material density, direct segmentation of base material was impossible. In the end, the porosity analysis of samples was created with the use of VGStudio MAX software.
