Abstract
This paper describes dynamical characterization of mechanical structures manufactured by Selective Laser Melting (SLM) process at various orientations. The samples are also compared to subtractive component. The additive metal samples were manufactured by a 3D printer (Renishaw AM 250, Renishaw) and were tested using vibration analysis of embedded-free beam installation. Experimental setup was replicated using the same geometry of samples printed at various orientations and submitted to low velocity impact. Accelerometers allowed recording mechanical responses of all the specimens, allowing characterizing the dynamic behavior of each component and the effect of the printing orientation and printing angles.
