Additive Manufacturing of Polymer‐Derived SiOC Ceramics: A Review of Materials, Techniques, and Applications

Additive manufacturing (AM) is revolutionizing the production of polymer‐derived ceramics, creating new trends for the design of materials with specific properties and structures. These properties are primarily attributed to their unique amorphous microstructure, which consists of a silica‐like network of dispersed silicon carbide (SiC) domains, with a percolating free carbon phase distributed throughout the structure. This unique structure enables precise tuning of mechanical, electrical, and thermal properties. This review presents a critical overview of the integration of AM and silicon oxycarbide (SiOC) materials science, providing a systematic roadmap from precursor chemistry and vat photopolymerization techniques to the fabrication of complex, application‐specific devices. The review illustrates how these tailor‐made structures translate into revolutionary applications across diverse fields, including aerospace, energy, biomedicine, and sensing. Furthermore, this review highlights major challenges arising from pyrolysis, including shrinkage and scalability, and show how emerging strategies, such as hybrid manufacturing and AI‐driven inverse design, can effectively overcome these obstacles. By linking microstructural control to macroscopic performance, this review not only summarizes current knowledge and research but also provides a robust framework for next‐generation research and the industrial‐scale use of additively manufactured SiOC ceramics.
