ABSTRACT:
The invention relates to a sheet lamination modeling method and a sheet lamination modeling apparatus for forming a three-dimensional object by stacking and gluing sheets together. In the invention, an upper sheet (2Y) is stacked on top of a lower sheet (2X) which is cut into an effective area (V1) constituting the three-dimensional object and a waste area (U1) not constituting the three-dimensional object, an adhesive (4) is supplied between the lower sheet (2X) and the upper sheet (2Y) and onto an area which extends outwardly of an overlapping area covering both of an effective area (V2) of the upper sheet (2Y) and the effective area (V1) of the lower sheet (2X) to thereby glue the lower sheet (2X) and the upper sheet (2Y) together, and the upper sheet (2Y) is cut into the effective area (V2) and a waste area (U2). As a result, according to the invention, it is possible to easily obtain a strong three-dimensional object without separation or deformation.
