Method for manufacturing three-dimensional shaped object, three-dimensional shaping system, and information processing apparatus

A method for manufacturing a three-dimensional shaped object, comprising:

• a stacking step of stacking a layer by discharging a shaping material from a nozzle while moving the nozzle with respect to a stage in accordance with shaping data with which a three-dimensional shaped object is shaped, the shaping data including path information indicating a movement path of the nozzle with respect to the stage and discharge amount information indicating a discharge amount of the shaping material in the movement path;
• and
• a data changing step of adding a cleaning command for cleaning the nozzle to the shaping data based on information included in the shaping data,
• wherein
• a timing of adding the cleaning command is determined according to at least one of the discharge amount of the shaping material, a discharge time of the shaping material, a number of times of the discharge of the shaping material from the nozzle, a length of the movement path, a number of the shaped layers, and a shaping time and,
• when the timing of adding the cleaning command is determined according to the discharge amount of the shaping material, adding the cleaning command to the shaping data based on an integrated discharge amount that is based on the discharge amount information corresponding to the movement path, and then resetting the integrated discharge amount.
