A method of manufacturing pre-formed, customized, ceramic, labial/lingual orthodontic clear aligner attachments (CCAA) by additive manufacturing (AM) may comprise measuring dentition data of a profile of teeth of a patient, based on the dentition data, creating a three dimensional computer-assisted design (3D CAD) model of the patient's teeth using reverse engineering, and saving the 3D CAD model, designing a 3D CAD structure model for one or more CCAA on various parts of each tooth, importing data related to the 3D CAD CCAA structure model into an AM machine, directly producing the CCAA in the ceramic slurry-based AM machine by layer manufacturing, enabling the provider to deliver patient-specific CCAA's by an indirect bonding method to the patient's teeth to improve the efficacy and retention of the clear aligners.

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.
