AB Additive manufacturing (AM) of metallic materials is increasingly being adopted innumerous sectors, such as biomedicine, aerospace or automotive industries, due to its versatilityin the creation of complex geometries and the minimisation of material waste when compared totraditional subtractive methods. In order to ensure a reliable operation of these parts, however, anin-depth study of the effect of additive manufacturing on mechanical properties, including tensile,fatigue and fracture resistance, is necessary. Among the vast number of methods and materials, thisproject is focused in one of the most promising techniques for the industry: Selective Laser Melting(SLM) for the production of a tools steel, in particular C300 steel components for the automotive sector.The main objective of this paper is to optimise some of the key parameters in the printing process,such as laser power, laser speed and hatch spacing. These variables are essential to obtain parts withgood resistance. To that purpose, tensile tests were performed in 3D printed specimens, and thenelastoplastic properties were extracted, organised and analysed through a design of experiments forthe subsequent output fitting using the response surface methodology.
