Abstract Scope |
Binder jetting is a multi-step additive manufacturing process in which metal powders are formed into a 3D shape through the deposition of binder, followed by sintering. The surface quality of the final parts surpasses that of prevalent powder bed fusion processes at lower costs. However, achieving the final part geometry while considering the sintering shrinkage in all three axes is a critical task that affects the reliability of the process. Employing trial and error for each design is not efficient. Thus, predicting the sintering behavior with numerical calculations is crucial. In this study, we conducted sintering experiments for binder-jetted SS316L parts using an in-situ camera monitoring set up. Then, we developed empirical fitting parameters for a continuum finite element model to calibrate the simulation predictions. This approach helps to achieve the desired shape and design guideline for binder jetting additively manufactured SS316L parts. |
