A New SFF Process for Functional Ceramic Components

SRI International in collaboration with Saint-Gobain/Norton Industrial Ceramics Corporation and Allison Engine Company is developing a new SFF process, Direct Photo Shaping, for the fabrication of functional ceramic components. The process is based on the layerby-layer photocuring of ceramic slurries containing monomers curable by visible light. Each layer is photoimaged by a liquid crystal display (LCD) or a digital light processing (DLP) projection system. After binder removal and sintering, the properties of silicon nitride tiles prepared according to the Dire~t Photo Shaping process were found to be comparable to properties of tiles formed by conventional methods.Mechanical Engineerin
