| Abstract Scope |
In this study, the anisotropy of parts produced via binder jetting is investigated during sintering across multiple scales, using a coupled Monte Carlo–Finite Element simulation framework. The process begins with the calibration and validation of a microscale Monte Carlo (MC) sintering model, benchmarked against experimental data obtained through X-ray computed tomography (X-ray CT) and optical microscopy at key densification stages captured via interrupted thermal cycles. Once validated, the model provides microscale descriptors such as strain and pore orientation, which are then incorporated as anisotropic sintering stress inputs into a continuum-level sintering model. This macroscopic model is based on the Skorohod-Olevsky Viscous Sintering (SOVS) finite element framework, tailored for 316L stainless steel. The continuum formulation accounts for key material behaviors, including the influence of initial relative density, grain growth kinetics, and the δ-ferrite phase transformation that occurs at elevated temperatures, friction and gravity. |
