### Mechanical Properties  
Figure 5 shows the tensile curves for samples tested in the XY and XZ directions. The results within each group are very similar, which suggests that the material was uniform and the samples were representative. However, there are clear differences between the two directions. The XY samples showed higher strength but had lower elongation. In contrast, the XZ samples had higher elongation, but their strength was lower. This difference is likely caused by the differences in morphological texture. In the XZ direction, the material had a column-like grain structure that allowed dislocations to move more easily. This decreased significantly the strengthening effect in this particular orientation.  
The tests were performed on the one selected sample that showed the most promising combination of relative density and hardness (Table 3).  
In the case of specimens constructed in the XY direction, we can observe higher strength parameters in the form of proof stress, determined for a permanent deformation

of 0.2% (R0.2 = 716 \(\pm\) 5 MPa), as well as for ultimate tensile strength (Rm = 827 \(\pm\) 7 MPa) compared to the XY direction (R0.2 = 613 \(\pm\) 2 MPa and Rm = 651 \(\pm\) 2 MPa). When analyzing the deformation capacity of the materials, we see an almost three times higher uniform deformation for the XZ direction compared to the XY direction (Ag = 42.8 \(\pm\) 2.3% for XZ and Ag = 15.5 \(\pm\) 0.6% for XY). This fact also translates directly into the total strain to rupture, which is higher for the material built in the XZ direction (A = 50.8 \(\pm\) 2.6% for XZ and A = 19.2 \(\pm\) 1.1% for XY). This high uniform strain for specimens built in the XZ direction is due to the relatively small strengthening process of the material during elongation in the uniform strain range--the slope of the tensile curves in the aforementioned strain range, for specimens built in the XZ direction, is much lower than for specimens representing the XY direction. Comparing the difference between the value of A and Ag, which defines the range of strain localization for us, we can conclude that it was approximately twice as large for specimens built in the XZ direction (8%) as for those built in the XY direction (3.7%).
