To easily manufacture a three-dimensionally shaped product using an ink jet three-dimensionally shaping device, and to facilitate the interfacial release between a model material and a support material after shaping, with regard to their separation method after shaping.
This three-dimentionally shaping device is constituted in the way that the model material which becomes a finished product and the support material which supports the model material during manufacturing, are created by means of an ink jet head with a plurality of nozzles. In the three-dimensionally shaping device, a nozzle for discharging the model material, a nozzle for discharging a first support material and a nozzle for discharging a second auxiliary support material having a release performance are provided. Consequently, liquids having different characteristics at the ink jet head are easily discharged, and the properties of releasability are provided between a conventional support material and a conventional model material. Further, the model material is easily separated from the support material without breaking, fusing or melting the support material.
