Abstract

Rapid Manufacturing (RM) technologies as Electron Beam Melting (EBM) and Selective Laser Melting (SLM) are able to produce fully dense parts from pre-alloyed powders in a layer-wise way. Moreover, they are able to create tailored surfaces with interconnected porosity. Applied to biomedical prostheses, such porosity can favour cell adhesion and osteointegration. The most important intrinsic characteristic of RM techniques is the large undercooling the parts undergo during the process. This undercooling results in peculiar, very fine, metastable microstructures, associated to peculiar mechanical behaviour. Metastable microstructures can change on post-melting operations, making the materials match the standard requirements and gain interesting properties.
