Three-dimensional object manufacturing apparatus and control method for the same

A control method, for a three-dimensional object manufacturing apparatus that includes:

• a mounting unit having a mounting surface on which a three-dimensional object being manufactured is mounted;
• a separator configured to separate the three-dimensional object from the mounting unit;
• a plurality of ink jet heads configured to discharge ink droplets to form the three-dimensional object;
• and
• a separation roller configured to move at least one of the three-dimensional object on the mounting surface and the separator, so as to prompt the three-dimensional object remaining on the mounting surface and the separator are to be placed in a predetermined position,
• the control method comprising:
• controlling the separation roller so as to move the three-dimensional object remaining on the mounting surface and the separator to a separating position at which the three-dimensional object is separated by the separator after the manufacturing of the three-dimensional object is completed,
• wherein the separator comprises a cutting portion that partly cuts the three-dimensional object to separate the three-dimensional object from the mounting surface,
• controlling the plurality of ink jet heads to discharge the ink droplets to form the three-dimensional object that is integrally formed of a body, a separation layer and a support material, wherein the separation layer is interposed between the mounting surface and the body, and the support material supports the body during the manufacturing of the three-dimensional object and is removed after the manufacturing of the three-dimensional object, and
• controlling the plurality of ink jet heads to discharge a same ink for forming the separation layer and the support material so that a material of the separation layer and a material of the support material are the same.
