1. A laminate molding system in which at least three or more press devices are continuously provided and a laminate molded article is sequentially pressure-molded, the laminate molding system comprising:
a first press device having a pressure reducible chamber and a pressurizing surface formed of an elastic body sheet, the laminate molded article being pressurized by a first driving force of a first servomotor;
a second press device having a pressurizing surface formed of a metal press plate or a pressurizing surface formed of an elastic body sheet, the laminate molded article being pressurized by a second driving force of a second servomotor;
a third press device having a pressurizing surface formed of a metal press plate, the laminate molded article being pressurized by a third driving force of a third servomotor, which are continuously provided; and
a control device for controlling operation of the laminate molding system,
wherein the control device is configured to measure, using a second position sensor provided in the second press device, a distance between board surfaces of an upper board of the second press device and a lower board of the second press device to obtain a board distance value after pressurization in the second press device, and further configured to perform position control of the third press device based on the board distance value,
wherein the board distance value provided in the second press device is stored as a reference position A in a storage device of the control device, and position control of the third press device is performed based on a position control value B,
wherein the position control value B is generated in the control device based on the reference position A.
