| Abstract Scope |
The Direct Ink Writing (DIW), or robocasting, of ceramics has been a point of focus to aid in the formation of complex geometries in the green state with high relative densities. The development of a paste as feedstock for DIW is highly dependent on maintaining the dispersed state of the ceramic particles throughout the printing process to ensure success in the print and post-processing. DIW paste must be a stable, well-dispersed shear thinning paste with a rapid recovery time for successful printing. In this presentation, multiple experiments were identified and used to develop an aqueous DIW feedstock paste for PMN-PZT ceramic powder as a function of dispersant content and pH while considering the solubility of the ceramic. Rheological measurements were conducted to ensure the developed paste had the desired rheological characteristics for DIW. |
