| Abstract Scope |
Binder jet parts undergo significant deformation during the sintering, a process that facilitates densification. This process-induced sintering distortion may result in parts with unacceptable geometric accuracy with the extent heavily dependent on the initial green density of the part. The current work investigates the effect of part size and location within the print build on the green density and proposes an approach to compensate input geometry based on mechanistic simulations using a data-driven method. Finally, the proposed approach's efficacy is validated both numerically and experimentally by comparing the deformed sintered shape against the target. |
