ABSTRACT:
A molding tool used for molding products of fibrous material is manufactured efficiently by employing a lamination molding method. A molding tool having a porous structure used for molding products of fibrous material such as pulp molding is manufactured by lamination molding method (a method for molding a three dimensional product by subjecting a material to be laminated to prescribed treatment, the method includes a photo-setting resin method). Material lacks or voids are formed on each layer of a laminating material, the layer is laminated one above another, thereby, many suction holes are formed on the molding tool as the material lacks.
