Abstract Scope |
This talk covers our recent research conducted at Texas A&M University on ceramic binder jetting additive manufacturing. First, a brief literature review is given. Then, our research results are presented to reveal the relationships among various densities, including apparent density, tap density, powder bed density, and green density. Next, our efforts in developing various feedstock powders are discussed, including granulated powder, multimodal powder, and coated powder. Afterward, our research results on the effects of process parameters are summarized, including ultrasonic hopper dispensing parameters, dosing ratio, layer thickness, roller rotation and traverse speeds during spreading, and printing orientation. Furthermore, our work on powder bed compaction is highlighted. Lastly, our research on infiltration as a post-processing method is discussed. |
