| Abstract Scope |
Additive manufacturing (AM) is a rapidly growing technology that has been a national priority and is actively explored for applications in aerospace, energy, defense, health, and electronic sectors. Its market size is projected to increase tenfold in the next five years. Additive manufacturing (AM) of ceramics is relatively more challenging with respect to polymers and metals, owing to their high sintering and melting temperatures, large thermal stress after sintering and solidification, and inherent brittleness that leads to cracking after processing. In this study, we explore the fabrication of high precision ceramic preforms using DLP process, followed by liquid silicon infiltration. Fully dense high precision ceramic components were obtained with complex geometries, including internal channels and chambers. Residual Silicon content of the components can be tuned by carbon additions. The combined DLP and LSI processes show the potential for AM ceramic applications. |
