Abstract
The invention utilizes green support structures during sintering to maintain the shape, reduce sagging and prevent separate part sections from coming into contact and fusing together during the sintering process. In the most preferred embodiment, monolithic green structures are form with integrated support green structures that are released from the parts after sintering. Preferably monolithic green structures are formed by the Mold Shape Deposition Manufacturing (Mold SDM) process. By the method described, complex sintered structures can be made having interlocking and independently movable interlocking parts.
