| Abstract Scope |
The rising demand for intricate ceramic applications has sparked increased interest in ceramic additive manufacturing. Specifically, polymer-derived ceramics (PDCs) are gaining attention due to their notable thermal and chemical properties. However, their shape manipulation often relies on manual or mechanical means, limiting their practicality. Active materials have emerged as promising alternatives for achieving reconfigurable systems. While material extrusion can make PDCs self-deformable, it has limitations such as low solid phase content and resolution. This hampers its application in fields requiring high accuracy like aerospace. To overcome these challenges, a novel vat photopolymerization method has been proposed to create reconfigurable and programmable PDCs. By employing a two-step curing process, controlled shape transformations are achieved, offering potential for programmable structures. This approach is compatible with high-resolution four-dimensional printing and boasts high solid content, addressing a significant research gap and presenting a novel avenue for developing PDCs with programmable shape transformation capabilities. |
