Direct manufacture of spatially engineered components for aerospace applications by fused deposition of ceramics

The current progress of the AlliedSignal led team using the Fused Deposition of Ceramics (FDC) process is described. The program is focused on building and characterizing novel designs with spatially engineered multiple materials. This paper will describe the design, fabrication and properties of multi-material turbine engine components. The integration of process parameters, material properties, material modeling and stress analysis within the FDC manufacturing process will be highlighted using the example of a multi-material turbine blade, improved build techniques to manufacture components not possible by regular techniques will also be demonstrated.
