Claim 11:
12. A three-dimensional shaping device comprising:
a stage;
a discharge unit comprising a nozzle configured to discharge a shaping material toward the stage;
a moving mechanism configured to move the discharge unit with respect to the stage;
a data generating unit configured to generate a first shaping data and a second shaping data; and
a control unit configured to control the discharge unit and the moving mechanism according to the first shaping data and the second shaping data to shape a three-dimensional shaped object on the stage, wherein
the data generating unit is configured to
generate the first shaping data representing a first discharge path along which the discharge unit moves while discharging the shaping material to form a first partial path, the first shaping data containing at least one of discharge amount information representing a discharge amount of the shaping material and movement speed information representing a movement speed of the discharge unit for forming the first partial path;
generate the second shaping data representing a second discharge path along which the discharge unit moves while discharging the shaping material to form a second partial path after the first partial path is formed, the second shaping data containing at least one of discharge amount information representing a discharge amount of the shaping material and movement speed information representing a movement speed of the discharge unit for forming the second partial path;
specify a gap portion sandwiched between the first partial path and the second partial path based on the first shaping data and the second shaping data; and
when the gap portion is specified, change the first shaping data corresponding to the first partial path by dividing the first partial path adjacent to the gap portion into a plurality of partial paths, and increasing a width of each of the partial paths according to change in a width of the gap portion so that the shaping material deposited on the stage in the first partial path increases.
