Abstract:
A method of forming a three-dimensional object by stacking and gluing sheets together, comprising the steps of providing a lower sheet cut into an effective area constituting the three-dimensional object and a waste area not constituting the three-dimensional object, providing an upper sheet to be stacked on top of said lower sheet, said upper sheet having an effective area constituting the three-dimensional object and a waste area not constituting the three-dimensional object, supplying an adhesive between said lower sheet and said upper sheet and onto an area which extends by a predetermined width outwardly of an overlapping area covering both said effective area of said upper sheet and said effective area of said lower sheet by an amount sufficient to prevent unglued areas from causing minor errors in stacking, thereby forming an effective adhesive layer, gluing said lower sheet and said upper sheet together, and cutting said upper sheet into the effective area and the waste area.
