PROBLEM TO BE SOLVED: To provide an apparatus and a method for foam molding capable of obtaining a half-stereoscopic image accurately reproducing the rugged shape of a stereoscopic article to become an object to be copied. SOLUTION: The apparatus 100 (200, 300) for foam molding forms a half- stereoscopic image of a three dimensional article by foaming a sheet-like foamable material FB based on the shape data of the article, and comprises a foaming unit FM for foaming the material FB, and a controller for controlling the foaming operation of the unit FM based on the shape data of the article. The unit FM directly heats the interior by focusing an infrared laser beam to a focal point F in the material FB to foam the material. Thus, sufficient foam amount can be assured. Preferably, the objective OL of the optical system OP of the unit FM is moved, and the material FB is irradiated with the beam while moving the point F of the beam in the thickness direction of the material FB. |
