ABSTRACT={Additive manufacturing (AM) is an innovative and promising technology that can create complex geometries with great precision. However, parts manufactured using this technology exhibit residual stresses and distortions, which hinder widespread adoption. Directed energy deposition (DED) stands out as a promising AM technique, offering a high deposition rate compared to other AM processes. DED uses a focused energy source, such as a laser or electron beam, to melt material as it is deposited, enabling the creation and repair of complex geometries. The flexibility in material usage and the ability to control the microstructure during the process makes DED suitable for high-performance applications in aerospace, automotive, and biomedical industries. Finite element modeling (FEM) of the DED process can predict the melt pool, and temperature profile without extensive experimentation, saving considerable time, material, and money. In the current study, the FEM of a high-layer thickness DED process is developed using the Gaussian heat source model to investigate the effect of different process parameters. The model aims to enhance understanding of the thermomechanical behavior during the DED process and to optimize process parameters for improved part quality and performance.}}
