Controller and three-dimensional modeling apparatus

A controller comprising:

• a processor controlling a three-dimensional modeling apparatus including a stage, an injection unit injecting a modeling material onto the stage, and a movement unit relatively moving the stage and the injection unit;
• and
• a memory unit in which modeling path information and correspondence information are stored, wherein
• the modeling path information is information representing respective modeling paths of N modeling layers formed using the modeling material injected from the injection unit,
• N is an integer larger than 1,
• the correspondence information is information in which overlap extent information representing an extent of overlap of the modeling paths and width information representing a width of the modeling path are correlated, the overlap extent information being based, in part, on angle data representing an angle formed by vectors at different locations along the modeling paths,
• the processor performs modeling control to model a three-dimensional modeled object in a predetermined shape by injecting the modeling material onto the stage using the injection unit and stacking the N modeling layers, and
• the modeling control includes width control to determine the width of the modeling path when the respective N modeling layers are formed by the injection unit based on the modeling path information and the correspondence information.
