Three-Dimensional Shaping Device And Data Generation Device

A data generation device that generates command data used in a three-dimensional shaping device including a first head having a first nozzle that extrudes a first shaping material and a second head having a second nozzle that extrudes a second shaping material, the data generation device comprising:

• a data generation unit configured to generate the command data based on shaping path data representing a movement path along which the nozzle moves while extruding the shaping material, wherein
• the data generation unit generates, as the command data,
• first deposition command data to deposit a layer of the first shaping material in a shaping region on a stage by extruding the first shaping material from the first nozzle along the movement path,
• cleaning command data representing a command to execute cleaning of the second nozzle, and
• second deposition command data to deposit a layer of the second shaping material in the shaping region by extruding the second shaping material from the second nozzle along the movement path after the cleaning is executed,
• the first deposition command data includes a deposition start command to start deposition of the layer of the first shaping material by starting extrusion of the first shaping material from the first nozzle, and a deposition stop command to stop the deposition of the layer of the first shaping material by stopping the extrusion of the first shaping material from the first nozzle,
• the cleaning command data includes a cleaning start command to start the cleaning and a cleaning stop command to stop the cleaning, and
• the data generation unit generates the cleaning start command and the cleaning stop command as commands to be executed between the deposition start command and the deposition stop command.
