Abstract

The aerospace industry has evolved in response to the growing demand for advanced designs and materials, aiming for lighter, faster, stronger aircraft with greater range. The Selective Laser Melting (SLM) technique is an additive manufacturing technology that uses a high-power density laser to melt metal powders in thin layers on a build platform. The stability of the melt pool is crucial for determining the microstructure, mechanical properties, and corrosion resistance of parts produced by SLM. In this research, an experimental and numerical evaluation of the additive manufacturing of AlSi10Mg using the selective laser melting technique was carried out. A good agreement between the numerical models and the experimental results was observed. The microstructure simulations provided detailed information on grain size and orientation, factors that directly affect the final properties of the material. The grain size distribution is directly related to the manufacturing conditions and its mechanical performance. This study explores the fabrication and modeling of lightweight alloys through innovative additive printing techniques.
