At this stage, it is not yet possible to assert that this innovative metal AM process is fully robust. However, the ongoing research indicates that progress is being made in the right direction. Particularly, investigating additional infill strategies would be of great interest, as the understanding of their effects is currently limited. Currently, surface roughness measurements are being performed for each of the 12 configurations using an optical profilometer Zeta. Additionally, metallographic analyses will be conducted on both the green (pre-sintered) and sintered parts to quantify the internal porosity, and all tensile fracture surfaces will be seen at SEM. These values will then be compared to the density measurements obtained using Archimedes' principle.
