ABSTRACT:
A method for manufacturing an integral three dimensional object from laminations includes the steps of fabricating a plurality of first sheets of a first material composition, cutting each of the first sheets to form a contoured layer representing a cross-section of the three dimensional object and to form a waste material and discarding the waste material. The contoured layers are stacked in a desired sequence to form a stack of contoured layers which are then laminated. Subsequently, the contoured layers of the stack are secured to each other to form the integral three dimensional object. This method works particularly well with ceramic material sheets. If desired, a second type of sheet made of a fugitive material can also be cut to form a contoured layer representing a void in a cross-section of the three dimensional object. The contoured layers of the second sheets are then stacked along with the contoured layers of the first sheets to form the object. The laminated stack of contoured layers is then sintered. During processing, fugitive material can be removed, leaving voids in the three dimensional object.
