Additive Manufacturing (AM) appears as a very interesting alternative to conventional production routes for alloys and metals, thanks the fact that at end of printing, final product is obtained directly. The present article looks inclusion duplex stainless steel 2205 (DSS-2205) in commercial catalog steels utilized powder bed fusion (PBF) technologies, specifically applying selective laser melting (SLM) technique. main objective establish optimal printing parameters reproduce closest results base material properties. To achieve this, response surface method was used methodology experimental design, studying power, scanning speed, hatching distance. A reference material, machined from hot-rolled plate, compare through tensile strength. Lastly, have been this steel. Additionally, study heat treatments has developed, aiming optimize austenitization process, achieving an improvement mechanical with properties practically identical those produced using techniques SLM.
