Three-dimensional modeling apparatus, manufacturing method and computer program

A method for manufacturing a three-dimensional object using a three-dimensional modeling apparatus for modeling a three-dimensional object by laminating a plurality of cross section bodies in a Z direction,

• the three-dimensional modeling apparatus including a head unit that models the object by discharging a liquid that is to be a material of the object into each unit grille that is defined in accordance with a modeling resolution of the cross section body in an X direction, a modeling resolution of the cross section body in a Y direction, and a lamination interval of the cross section body in the Z direction, and
• the unit grille having a plurality of sub unit grilles aligned in the Z direction,
• the head unit being configured to individually discharge, into each of the sub unit grilles, an achromatic liquid and a plurality of types of chromatic liquids in designated amounts,
• the method comprising, in a case where a designated amount of one of the plurality of types of chromatic liquids is discharged into each of the sub unit grilles by controlling the head unit and the spatial volume of the sub unit grille is not filled, discharging the achromatic liquid into the sub unit grille in addition to the chromatic liquid so as to fill the spatial volume of the sub unit grille.

A computer program for manufacturing a three-dimensional object by causing a computer to control a three-dimensional modeling apparatus for modeling a three-dimensional object by laminating a plurality of cross section bodies in a Z direction,

• the three-dimensional modeling apparatus including a head unit that models the object by discharging a liquid that is to be a material of the object into each unit grille that is defined in accordance with a modeling resolution of the cross section body in an X direction, a modeling resolution of the cross section body in a Y direction, and a lamination interval of the cross section body in the Z direction, and
• the unit grille having a plurality of sub unit grilles aligned in the Z direction,
• the head unit being configured to individually discharge, into each of the sub unit grilles, an achromatic liquid and a plurality of types of chromatic liquids in designated amounts,
• the computer program causing the computer to function such that, in a case where a designated amount of one of the plurality of types of chromatic liquids is discharged into each of the sub unit grilles by controlling the head unit and the spatial volume of the sub unit grille is not filled, the achromatic liquid is discharged into the sub unit grille in addition to the chromatic liquid so as to fill the spatial volume of the sub unit grille.
