Symposium Additive Manufacturing of High and Ultra-high Temperature Ceramics and Composites: Processing, Characterization and Testing
Presentation Title Vat Photopolymerization-based Additive Manufacturing of Different Non-oxide Ceramics
Author(s) Martin Schwentenwein, Shawn Allan
On-Site Speaker (Planned) Shawn Allan
Abstract Scope This paper focuses on the advances concerning vat photopolymerization-based AM of aluminum nitride, silicon nitride and silicon carbide-based ceramics. This contribution will show that it was possible to produce components with the same thermal and mechanical properties as from parts made by conventional manufacturing (isostatic pressing). With a relative density of 99.8 %, a hardness of 1500 and a biaxial bending strength of >760 MPa the tested composition is exactly at eye-level with conventionally processed silicon nitride. For aluminum nitride components with a thermal conductivity of >200 W/m.K were obtained. These material properties in combination with the high precision of the LCM process allow the production of highly complex and fully functional components that have not been feasible before. Beside the printing process and the properties of the ceramic material, this presentation will also give an outlook on the status of silicon carbide.
