<P>PROBLEM TO BE SOLVED: To provide a three dimensional shaping apparatus which can efficiently recover, with simple constitution, an excess powder material other than the material necessary for forming a three dimensional shaped object among the powder material supplied to a stage. <P>SOLUTION: The three dimensional shaping apparatus is provided with a stage on which the powder material can be loaded and which has a shaping region for forming the three dimensional shaped object and a non-shaping region, an ejection section capable of ejecting a shaping liquid to the powder material, a moving mechanism for moving a relative position of the ejection section toward the powder material loaded on the stage and a control section for controlling an action of the ejection section to eject the shaping liquid and an action of the moving mechanism to move so as to be able to eject the shaping liquid to the powder material in the shaping region. Further the three dimensional shaping apparatus is characterized by having openings provided in the shaping region and the non-shaping region on the stage, a powder recovering section for storing the powder material dropped from the openings, a shutter member for closing the openings and a driving section which can close the openings in the shaping region and can drive the shutter member so as to release the openings in the non-shaping region. <P>COPYRIGHT: (C)2012,JPO&INPIT |
