Despite the fact that 3D printing has been developed for tens of decades, problems still exist when it comes to fabricate overhang structures or other complicated structures. To reduce this problem, researchers have made attempts on introducing novel concepts into 3D printing. Four-dimensional (4D) printing is one of these attempts and it has been successfully applied to fabricate plastic and hydrogel parts. This proposed project aims at extending the application of 4D printing into fabricating complicated ceramic materials via controlling ZrO2 contents. The additional shape change will result from different shrinkage degrees of different layers upon heating, thus generating desired part shapes. This proposed project will provide a new route of generating complex ceramic structures via 4D printing. In addition, this project will advance our knowledge on 3D printing and provide us with hands-on experience in the cutting-edge 3D printing technologies.
