NUMERICAL INVESTIGATION OF THE EFFECTS OF SCANNING DIRECTION AND LASER POWER DENSITY ON THERMOMECHANICAL BEHAVIOR IN ADDITIVE MANUFACTURING USING THE DED METHOD
Abstract
In this study, the effects of different scanning direction and laser power density conditions on the thermomechanical behavior of metal additive manufacturing via the Directed Energy Deposition (DED) method were investigated through numerical simulations. A three-dimensional thermomechanical analysis model was developed using Simufact Welding software to evaluate the temperature distribution, thermal stresses, and plastic deformation behavior under two scanning directions and laser power densities. The results revealed that both scanning directions and laser parameters significantly influence temperature gradients and the accumulation of residual stress fields. In particular, more homogeneous temperature distributions were achieved at lower laser power levels, which in turn resulted in reduced residual stresses. The findings emphasize that the optimization of scanning direction and energy input parameters is essential to ensure manufacturability and enhance the structural integrity of parts fabricated through the DED process.
