Investigation of T4 and T6 heat treatment influences on relative density and porosity of AlSi10Mg alloy components manufactured by SLM

•Influences of process parameters on densification and porosity of AlSi10Mg samples.•Influences of heat treatments on the densification and porosity.•The densification was enhanced with reduction in porosities by T6-heat treatment.•Optimized parameters are beneficial for designers to manufacture AlSi10Mg parts.
