The DEVCOM-Army Research Lab is focused on enabling the ability to produce heterogeneous dense ceramics with mesoscale tailoring and compositional control. Structures, such as functional gradients, have been shown to exhibit unique extrinsic behaviors in the bulk that are not inherent to the intrinsic behaviors of the constituent materials. Combining advanced ceramics to achieve enhanced structural and thermal properties are especially of interest. This presentation will discuss the ongoing investigation into utilizing additive manufacturing techniques to enable this mesoscale tailoring in structural ceramics. Non-oxide ceramics, such as silicon carbide, boron carbide, and ultrahigh temperature ceramics will be discussed. Utilization of direct-ink-write to co-print multiple highly-loaded particulate suspensions will be presented. Post-processing and sintering challenges of the printed heterogeneous parts will also be discussed. New efforts looking at the reactive sintering methods to enable co-deposition of ceramic and metal systems will be shown as well.
