Additive Manufacturing (AM) technology, commonly known as 3D printing, has been recognized as a transformative method in various industries such as automotive, medical, defense, power generation, aerospace, shipbuilding, and heavy equipment. Evolving from prototyping to mass production, AM is now being utilized for manufacturing complex and precise metal components that demand intricate geometries. The research systematically explores key LPBF parameters, including laser power, scanning speed, and layer thickness to understand their impact on the microstructure and mechanical behavior of the resulting IN718 components. Through a comprehensive analysis of the fabrication process, we aim to identify the optimal parameter set that ensures the desired mechanical properties, including tensile strength, hardness, and fatigue resistance.Additionally, the study employs advanced characterization techniques such as microscopy and mechanical testing to assess the material's performance under different conditions. The findings presented in this research provide valuable insights for enhancing the reliability and efficiency of LPBF-produced IN718 components in aerospace, automotive, and other high-demand applications.
