| Abstract Scope |
In binder jetting (BJT) additive manufacturing (AM), jetted liquid binder binds powder particles and provides structural integrity to the printed green parts. While the effects of binder saturation on the green part quality have been explored, the study of the impact of binder on part densification and subsequent part properties is limited. Through experimental results, the authors demonstrate that the presence of binder in the green part can limit its densification, alter its shrinkage, and affect the final grain structure and resultant part properties. Through tailored binder deposition within each layer, the authors demonstrate the ability to volumetrically control these properties to induce unique functionalities, including improved final part density, locally controlled grain growth, tailored green strength, and embedded internal signatures that can be used for anti—counterfeiting applications. |
