A fabrication method, direct coagulation casting (DCC), is presented which may be suitable for the mass production of complex ceramic parts with high-strength and reliability.This near net shape casting method relies on an enzyme-catalyzed pH change to effect coagulation of the ceramic slurry, producing a rigid green body.The use of DCC can avoid most of the limitations of conventional shaping techniques, and it can be applied to a large variety of ceramic powders, sols, and polymers, alone or in combination.
