Abstract Scope |
This study aims to evaluate the manufacturability of stainless steel 316L cylindrical samples using the directed energy deposition (DED) additive manufacturing technique, assessing its potential through finite element method (FEM) analysis. The precision of the FEM analysis was evaluated by comparing the results with three-dimensional scans (Light scan) of physical models. This assessment aimed to quantify any discrepancies between the virtual and real models, thereby evaluating the predictive capability of the simulation software for estimating residual stresses and deformations throughout and at the end of the printing process. Mechanical properties were investigated using microhardness tests, while microstructural properties were analysed via optical microscopy (OM) and scanning electron microscopy (SEM). The effects of heat treatments on both mechanical and microstructural properties were also investigated. The findings provide insights into the reliability and accuracy of DED process simulations and their practical implications. |
