Abstract Extrusion freeform fabrication (EFF) and fused deposition of ceramics (FDC) processes are established extrusion-based freeforming techniques capable of fabricating complex shaped monolithic ceramic prototypes by the sequential deposition and solidification of green ceramic feedstock. In these processes, ceramic parts are produced using a commercially available Stratasys 3-D Modeler retrofitted with modified extrusion heads suitable for extruding ceramic materials. The manufactured objects have good dimensional tolerances as well as engineering compositions and microstructures. The process is flexible and can be used for different monolithic ceramic materials such as silicon nitride, alumina, and zirconia. (Auth abstract) [References: 17] XX
