Abstract Scope |
The green structures formed by Direct Ink Writing (DIW or Robocasting) technique exhibits anisotropy at various length scale, distinguishing them from conventionally processed green bodies. In this study, we have compared the densification kinetics and microstructure evolution of alumina structures processed by slip-cast and robocasting techniques. A slurry with optimized solid content of 55 vol% alumina was prepared with DI water as a solvent and printed using a robocaster. A 50 vol% alumina slurry was prepared for slip casting. Both the structures were sintered at different temperatures for 2 hours in air. The densification kinetics and microstructural evolution has been compared for the robocast and slip-cast samples. This study is part of a larger project to develop a comprehensive sintering model for additively manufactured ceramics. |
