A method of forming a ceramic component is disclosed. A ceramic matrix material is combined with a binder material. The ceramic matrix material and the binder material are mixed to create an intermediate slurry. After mixing the ceramic matrix material and the binder material, reinforcing fibers are added to the intermediate slurry to create a final slurry. The final slurry is introduced into a mold cavity having a shape corresponding to the ceramic component. The final slurry is at least partially cured within the mold cavity to form an intermediate casting. The intermediate casting is sintered to produce the ceramic component from the intermediate casting.

This invention relates to three-dimensional printing. This invention in particularly relates to a system for drying a paste-based crafting medium during three-dimensional printing and a method thereof. The system can comprise a dual printhead comprising a first dispensing nozzle for depositing the filament material for a mold layer in a flowable fluid form and a second dispensing nozzle for depositing the crafting medium, which is in a paste form. The system also includes a drying means which can be a heating system or a drying apparatus, that in some embodiments can be attached to the printhead. The three-dimensional imaging process for making objects, preferably metal objects or ceramic objects, on a layer-by-layer basis under the control of a data processing system is disclosed. The drying of the object or mold is crucial in the three-dimensional imaging process because it can affect the overall quality of the object. A solution to this problem is achieved in the present invention by using a drying step after finishing each layer of the object (both mold and paste). This is achieved in some embodiments by using a drying apparatus comprising a radiating heater and air circulation fan mounted on to the moving print head. The print head can repeatedly scan the printed layer and apply heat and air circulation to improve drying in a controlled manner. This system and method provides improved evenness in the drying and reduces the risk of cracks developing in the deposited object, and also reduces the risk of further problems during the subsequent processing steps to provide the finished object.

This invention relates to three-dimensional printing. This invention in particularly relates to a method of fabricating a three-dimensional object using a support edifice and also using a mold material with structural additives. The support edifice is fabricated in the same crafting material as the final three-dimensional object in the same manner as the printing of the final three-dimensional object (mold and crafting in a layer by layer manner). This method enables the support edifice to also transform during post processing in the same manner as the final three-dimensional object, thus supporting the object until finished. The system for fabricating the object comprises a dual printhead comprising a first dispensing nozzle for depositing the filament material in a flowable fluid form and a second dispensing nozzle for depositing the crafting medium, which is in a paste form. The printhead can also include a heating system or a drying apparatus. The three-dimensional imaging process for making objects, preferably metal objects or ceramic objects, on a layer-by-layer basis under the control of a data processing system is disclosed. The printing of the three-dimensional object such as heavy objects or an object having different parts having a very thin gap or space. It is important to use different processing steps and/or material to print such three-dimensional objects. The present invention provides a solution by printing a support edifice comprising a special structural additive for the mold, and further the support edifice can be printed simultaneously while printing the mold and crafting-paste material on a layer-by-layer basis. The mold material is mixed with the structural additive. The structural additive is useful for prohibiting either fusing of the object with the support edifice, or in alternative embodiments, the fusing of one part of an object with another part of an object.
