Introduction Powder Metallurgy (PM) engineering starts to use a new possibility of design controlled by the new technologies, led by additive manufacturing (AM), ultrasonic-assisted compaction or/and sintering, severe plastic deformation (SPD) and it has a huge potential to disrupt current manufacturing process processing.
Mainly AM is to take care of a forum demonstrating the depth and breadth of the research and development activities through manufacturing technology which most describes that goal [1-4].
Critical to further advances in this topic, will be the systematic study of the influence of important AM variables.
