Shaping ceramics into complex three-dimensional geometries is desirable yet challenging. 3D/4D printing has attracted tremendous attention in ceramic machining, but it is still difficult to make structures with hierarchy spanning different length scales. Our group reported a mechano-plastic pyrolysis process that overcomes this limitation. The mechano-plasticity resulted in simultaneous shape control at both micro- and macro-scales. Further pyrolysis led to complex ceramic structures that are otherwise difficult to produce. This process offers an avenue for efficient fabrication of hierarchical three-dimensional ceramic structures suitable for engineering applications. The paper has been published in Adv.
