| Abstract Scope |
Robocasting of ceramics offers a simple process, yet has limitations in geometrical freedom due to the need for external supports. Previous research explored the potential of origami robocasting, which involves printing a flexible green body that can be reshaped. However, the ink formulations used before mainly rely on preceramic polymers with good elasticity, which are often limited to silicon-based ceramics and may result in large shrinkage and/or low density in the final part. In our work, a slurry-based ink with flexible polymeric binders and a wide range of material options is used for robocasting origami-folded parts. Our results show that sintered alumina produced with this ink exhibited high density and moderate shrinkage while retaining manipulated shapes without any adverse deformation. The use of this ink for ceramic origami opens up many possibilities for creating advanced geometries in various applications, including aerospace components, biomedical scaffolds, and precise catalyst supports. |
