Apparatus for modeling three-dimensional object and method for modeling three-dimensional object

A method for forming a three-dimensional object by a fused deposition modeling method, the method using:

• a plurality of material resin suppliers, each of the plurality of material resin suppliers is configured to supply a coloring material resin of a different color, and the coloring material resins are resins to be used as a modeling material;
• and
• a mixed resin ejector configured to shape the three-dimensional object using a mixed resin while ejecting the mixed resin, which is a resin obtained by mixing the coloring material resins that are supplied from the plurality of material resin suppliers,
• wherein the three-dimensional object is configured by stacking a plurality of layers formed by the mixed resin ejected from the mixed resin ejector,
• the plurality of material resin suppliers being configured to supply the coloring material resins of different colors to the mixed resin ejector, respectively,
• the method comprising:
• controlling amounts of the coloring material resins to be supplied from each of the plurality of material resin suppliers to the mixed resin ejector, thereby adjusting a color of the mixed resin that is to be ejected by the mixed resin ejector,
• wherein a resin supply controller is configured to control the amounts of the coloring material resins to be supplied from each of the plurality of material resin suppliers to the mixed resin ejector,
• wherein
• the resin supply controller is configured to control an ejection amount of the mixed resin to a predetermined constant amount;
• the plurality of material resin suppliers being configured to supply the coloring material resins of different colors to the mixed resin ejector based on a color information indicating the color of the mixed resin;
• the material resin of at least one of a white color or a clear color is supplied by a backup material resin supplier;
• and
• during the adjustment of the color of the mixed resin based on the color information,
• the backup material resin supplier is configured to additionally supply the material resin of at least one of the white color or the clear color such that the ejection amount of the mixed resin from the mixed resin ejector is the predetermined constant amount in response to detecting a total amount of the coloring material resins supplied by the plurality of material resin suppliers is less than the predetermined constant amount.
