Fig. 3

Stress-strain curves for unconfined compression tests of cubes reticulated at 941 mW of perpendicular samples – first slope for each curve on the left axis and complete curve for each sample on the right axis. In blue are highlighted the regions where yield strength, deformation and ultimate strength and deformation were obtained while arrows represent the linear, plastic and densification regions of the curves. Beside the figure is sketched the applied force for perpendicular and parallel measurements in respect to printing lines
