Summary

This paper describes recent progress in using the Mold SDM process for the fabrication of structural ceramic components. The primary application is currently silicon nitride components for use in gas turbine engines. Mold SDM is an additive-subtractive layered manufacturing process which builds fugitive wax molds which can then be used to make ceramic parts by gelcasting. Mold SDM is capable of making complex shaped ceramic parts with smooth surfaces and fine features. Example parts will be shown together with mechanical property data.
