| Abstract Scope |
In this study, an aqueous ZrB2 slurry previously developed for injection molding was adapted for the additive manufacturing technique of direct ink writing (DIW). Important to the success of modifying this slurry is the ability to print the ink into more complex shapes, reduce porosity, and increase density. The original slurry developed for injection molding needed a change in rheology to increase yield stress to enable the support of multiple printed layers. Modifications of the solids loading and polymer content were successful in producing a printable ink. Here, we will present preliminary printing studies on infilled shapes using the modified slurry, with future work to include more complex shaped printing and material characterization. The alteration of the ink for DIW allows for further advancements of the slurry with an optimized ink that widens the range of aqueous ZrB2 printing possibilities. |
