Three-dimensional data generation device, three-dimensional shaping device, and shaped object shaping method

A three-dimensional shaping device comprising:

• a data division unit that divides sectional shape data on one layer of a shaped object into mark data for shaping a mark for correction of sectional shape data on a different layer to be output as superposed on the one layer and post-removal data obtained by removing the mark data from the sectional shape data on the one layer;
• a detection unit that detects an amount of misregistration of the mark output using the mark data from a position determined in advance;
• an output command unit that commands output using the post-removal data so as to form the one layer of the shaped object together with the mark;
• a data correction unit that corrects the sectional shape data on the different layer using the amount of misregistration of the mark detected by the detection unit;
• and
• an output unit that outputs the mark using the mark data, outputs a portion obtained by removing the mark from the one layer using the post-removal data, and outputs the different layer of the shaped object using the sectional shape data on the different layer corrected by the data correction unit.
