PROBLEM TO BE SOLVED: To reduce the possibility of destroying a three-dimensional body composed of a photosetting resin when the three-dimensional body after molding is heated. SOLUTION: A coagulant SL not yet coagulated is applied on the surface of a laminate LS to form a coagulant layer SLL and controlled by a cooling roller 30 to cure the coagulant SL. Laser beams are emitted on desired areas R1 and R2 of the coagulant layer SLL to gasify and remove the coagulant SL, and photosetting resin PA is filled in the areas R1 and R2. Then the given beams are emitted to cure the photosetting resin PA. As for the coagulant SL, a mixture composed of urea into which polyvinyl alcohol and an eutectic compound are added and provided with the thermal expansibility almost equal to the thermal expansibility of photosetting resin is used. |
