Additive manufacturing is use to build three-dimensional parts, from a CAD model. The parts are constructed, layer by layer from powder, and selectively melted by laser or electron beam in the powder bed fusion process. This method enables the production of complex geometries of versatile materials parts. In this study, powder laser bed fusion technique was used to make AlSi10Mg extrusion billets. The AM billets were subjected to stress relief Heat Treatment (HT) and hot extrusion process. The mechanical properties and microstructure of the extruded AM billets and aged hardened were evaluated. A significant improvement of the extruded samples mechanical properties was found in comparison to cast and as-built material. In some cases, the yield stresses, tensile stresses and elongation were found to increase by 30-40%. Manufacturing of extrusion billets by additive manufacturing can be consider as means to gain better mechanical properties of final heavy-duty products by extrusion.
