A method and apparatus automatically fabricates a three dimensional object from individual layers of fabrication material having a predetermined configuration. Successive layers are stacked in a predetermined sequence and affixed together to form the object. The fabrication material is carried on a substrate to a stacker. At the stacker the layers are stacked together, with each layer being successively affixed to the stack of previously affixed layers, and with the substrate removed from each layer after it is affixed.

[ We claim:] [1.] A method for fabricating a three-dimensional object from fabrication material formed into individual layers, where successive individual layers are stacked to form said object,said method including(a) providing a station where the successive individual layers are formed into a stack,(b) placing on a carrier substrate a first layer of fabrication material corresponding to the configuration of one individual layer,(c) conveying the first layer of fabrication material on said carrier substrate to said station,(d) prior to separating the carrier substrate selectively inducing bonding of at least a portion of the fabrication material to the stack, and(d) separating said carrier substrate after bonding said one individual layer to said stack by incrementally pulling the substrate from the layer of fabrication material to expose a bonding surface on the layer of fabrication material.
