Abstract:

Freeze-form Extrusion Fabrication FEF is an environmentally friendly solid freeform fabrication method that uses aqueous pastes to fabricate ceramic-based components. The process uses only small quantities 2 to 4 vol. of organic binder. Using the FEF process, 3-D ceramic components have been fabricated from aluminum oxide Al2O3 by extrusion deposition of Al2O3 paste in a layer-by-layer manner utilizing a 3-D gantry controlled by a computer using Labview software. Sintered samples have achieved 98 of their theoretical density, demonstrating the feasibility of the FEF process.
