Method for manufacturing three-dimensional shaped object and three-dimensional shaping device

A three-dimensional shaping device comprising:

• a stage;
• a discharge unit configured to discharge a shaping material toward the stage;
• a position change unit configured to change a relative position between the discharge unit and the stage;
• a control unit configured to control the discharge unit and the position change unit according to shaping data for shaping a three-dimensional shaped object layer by layer, the shaping data being generated based on shape data indicating a shape of the three-dimensional shaped object, and configured to shape the three-dimensional shaped object on the stage by discharging the shaping material from the discharge unit to laminate a plurality of layers;
• and
• a measurement unit configured to measure a physical quantity of the layers laminated on the stage, wherein
• the control unit executes
• a first lamination step of laminating an n-th layer, n being any integer of 2 or more,
• a measurement step of measuring a physical quantity of an (n−1)-th layer by the measurement unit,
• a data processing step of preparing the shaping data for an (n+1)-th or more layer, and
• a second lamination step of laminating the (n+1)-th or more layer according to the shaping data prepared in the data processing step, and
• in the data processing step, the control unit executes
• a correction step of preparing the shaping data for the (n+1)-th or more layer by correcting the shaping data generated in advance based on the physical quantity, or
• a generation step of generating the shaping data for the (n+1)-th or more layer based on the physical quantity and the shape data.
