AB A customized Al-Cu-Mg-Si alloy is successfully processed by selective laser melting. AlSi10Mg powder,used as a master alloy, has been mixed with pure Cu powder through a fluidized bed and the obtainedpowder mix was used as feedstock material for the printing process. To investigate the feasibility of theprocess and to discuss the effect of the process parameters, a two-step experimental campaign has beencarried out: in the first batch of experiments the energy density has been varied to frame the processingwindow while in the second batch the energy density has been kept constant and the main processparameters have been varied to highlight their influence on the process. Density, porosity, and microhardness have been chosen as output to evaluate the success of the process. The microstructure and composition phase were studied through scanning electron microscopy and X-ray elemental mapping,respectively. A maximum relative density of 97% has been obtained while a predominant role of the laserbeam power has been observed.
