Abstract:
A method of lamination molding, in which a material to be laminate-molded is made of a resin layer and a lamination member having convex shapes and the convex shapes of the material to be laminate-molded is embedded in the resin layer, the method comprises the steps of:disposing the material to be laminate-molded between smooth pressurizing surfaces, at least one of those surfaces comprising a pressurizing plate that is deformable resiliently,depressurizing between the resin layer and the material to be laminate-molded and thereabout without pressurizing the resin layer and the material to be laminate-molded, andmelting the resin layer while keeping the depressurizing,wherein by pressurizing the material to be laminate-molded at a given pressure by there pair of smooth pressurizing surfaces initially comprises pressurizing the at least one of the pressurizing surfaces comprising the pressurizing plate so that it is deformed resiliently in accordance with the convex shapes of the material to be laminate-molded, and subsequently restoring of the pressurizing surface comprised of the pressurizing plate to the smooth state to mold the surface of the molded product smoothly on both sides as a result of a main clamping process.
