Abstract
A three-dimensional shaping device includes a position changing unit configured to change relative positions of a first head having a first nozzle and a stage and relative positions of a second head having a second nozzle and the stage, a cleaning part configured to clean the second nozzle, and a control unit. The control unit executes first deposition processing of depositing a layer of the first shaping material in a shaping region by extruding the first shaping material from the first nozzle while changing the relative positions of the first head and the stage, cleaning processing of cleaning the second nozzle using the cleaning part, and second deposition processing of depositing a layer of the second shaping material in the shaping region by extruding the second shaping material from the second nozzle while changing the relative positions of the second head and the stage after the cleaning processing. A start timing and an end timing of the cleaning processing are included in an execution period of the first deposition processing.
