Abstract
A first plastic film 90 is prepared which is cut into an effective area V1 constituting a three-dimensional object and a non-required area U1 not constituting the three-dimensional object, and a second plastic film 94 is fed above the first plastic film 90. Meanwhile, a photo-setting adhesive 96 is applied on a lower surface of the second plastic film 94, and a portion 96a corresponding to a sum of the non-required area U1 of the first plastic film and a non-required area U2 of the second plastic film is solidified whereas a residual portion 96b remains non-solid. The non-solid portion 96b is irradiated with a light beam and solidified to attach the first and the second plastic films with each other. The second plastic film 94 is then cut into an effective area V2 and the non-required area U2. The three-dimensional object is formed by successively laminating plastic films through repetition of the above steps.
