Abstract
Advanced manufacturing, more specifically additive manufacturing, has been increasingly explored since the emergence of the so-called Industry 4.0. 3D printing techniques, including the great diversity of technologies and materials that can be used, allow a wide range of applications. In order to further explore and deepen the studies related to this topic, this research investigated the mechanical properties of PH1 stainless steel, manufactured in an EOS M280 printer through the Direct Metal Laser Sintering process, or DMLS for short. The characteristics of the material were explored, identifying influences of the form of manufacture and comparing its measured properties with those reported by the printer manufacturer and with similar laminated materials found on the market. Different printing orientations were analyzed, in addition to the difference between parts produced with and without heat treatment, which is recommended by the manufacture because parts manufactured by this method contain a high amount of residual stress. The tensile, roughness, hardness, impact tests and the M.E.V. analysis were selected considering obtaining the most relevant properties of the material for the industry of the parts produced by the technology. The measured results were compared with those obtained by traditional manufacturing, so that it was possible to analyze the feasibility and reliability of replacing the manufacturing method. These indicate that the printed material is resistant and can replace parts obtained by traditional manufacturing, but it must be used with some care, as it is very much affected by the printing orientation, showing very different results appearing in some cases to be even different materials. Additionally, a script for the digital manufacturing of spare parts, considering different scenarios, was developed, to allow the manufacture of parts that, together with the mechanical tests performed, allows the evaluation of the path to be followed within the additive manufacturing for each part.
