Abstract

A laminate molding system in which three or more press devices are continuously provided and a laminate molded article is sequentially pressure-molded. The laminate molding system includes first, second and third press devices. The first press device includes a pressure reducable chamber and a pressurizing surface formed of an elastic body sheet or a pressurizing surface formed of an elastic body sheet, the laminate molded article being pressurized by a driving force of a servomotor. The second press device includes a pressurizing surface formed of a metal press plate, the laminate molded article being pressurized by a driving force of a servomotor. The third press device includes a pressurizing surface formed of a metal press plate, the laminate molded article being pressurized by a driving force of a servomotor.
