Abstract
Additive manufacturing (AM) is on its way to become the next industrial revolution. The growing interest on the subject has undoubtedly attracted many scientists in diverse areas of expertise. This attractively is justified by the large degree of freedom allowed by these technologies to design features of unequalled level of complexity with limited dependence on tooling. This work will briefly introduce the types of AM technologies available today. It will also address the new trends in additive manufacturing, manufacturing concepts, process optimization, and materials for 3D printing, designs, and microstructural interpretation of the mechanical characterization of 3D printed parts. As a case study, printability of varieties of polymers is explored using fused deposition modelling (FDM) technique. In particular, the induced microstructure, the thermal behaviour during lying down and the mechanical performance are evaluated and discussed. Finally the ranking of 3D printed parts according to the feedstock material properties is proposed based on simple mechanical criteria.
