Abstract Scope |
The interaction of the jetted binder and the powder particles is the primary determinant of the quality of binder jetting parts. Understanding the interaction in the context of green part accuracy is critical to fabricating dimensionally accurate final parts. Prior studies on accuracy have focused on processing parameters such as binder saturation, layer thickness, and printing speed. However, the study of accuracy in the context of binder-powder interaction is limited. In this study, the authors propose a standard benchmark artifact containing features uniquely designed to quantify binder-powder interaction effects on green part accuracy and resolution. To explore the effects of binder and powder size on part resolution and accuracy, the benchmark artifacts are printed with varying powder size (30 µm and 5 µm), binder droplet size (10 pL and 30 pL), and binder saturation ratio (75%, 100%, and 150%); measurements of dimensional variation are reported. |
