Abstract
A method of making a three-dimensional object constituted of a large number of layers bonded together, each having the contour of a thin slice of the object, is characterized in that each layer is precisely contoured after having been bonded to the partially-built three-dimensional object but before the next succeeding layer is bonded to it. Each layer is a preformed sheet and is bonded to the partially-built object by applying an adhesive at locations within the confines of the contour of the area of contact between the layer to be bonded and the object, such that the portions of the sheet outside of the contour of the contact area are easily separated.
