Abstract
Owing to their high thermal stability, oxidation resistance, and corrosion resistance, polymer-derived ceramics (PDCs) have attracted extensive attentions to fabricate complex-shaped ceramic parts that can be used in high-tech industries. While flexible PDCs offer structural reconfiguration, methods for inducing shape changes primarily rely on mechanical loads, such as manual loading, motors, or pneumatic pumps, which is considered impractical and requires complex control systems. To address these issues, a vat photopolymerization (VPP)-based four-dimensional (4D) printing method has been proposed and developed to manufacture PDCs with reconfigurable and shape memory effects for the first time. This innovative 4D printing method is highly programmable and compatible with VPP technology, allowing the fabrication of high-resolution, intricately designed ceramic structures with a high solid content. Through a two-step curing process, autonomous shape transformations of the PDCs have been achieved.
