pores in the unidirectional printing. It is further remarked that at this stage of the tomography analysis, considering either 2D scans or a 3D reconstruction of the outer contours may not lead to the same conclusion regarding which of the specimens displays the largest proportion ofpores. It is however confirmed that the pores are more dispersed with the crisscross printing, concerning both their spatial distribution and their sizes. Defacto,this 3D reconstruction enables to measure the total volume
