Abstract

In recent years, 3D-printing technologies are able to fabricate complex shapes of a custom designed component by adding material layer-by-layer from the bottom up on top of each other. Electron Beam Melting (EBM) is a technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers in order to form finished components. Aim of this paper is to perform a FEM analysis of custom-made implant in order to calculate the stress-strain state under daily activities loading. To this purpose, geometry, mechanical properties and boundary conditions have to be known. Geometry was reconstructed with a reverse-engineering process while loading conditions were obtained from literature. Ti6Al4V mechanical properties were determined experimentally with tensile testing. A deeper local analysis was carried out in order to simulate bone-screw interface to define if daily activities can cause bone resorption
