Abstract

A three-dimensional shaping device (10) includes: an injection unit (100) that injects a shaping material from a nozzle (60); a stage (220); a drive unit that changes a relative position between the injection unit and the stage; a cleaning mechanism that includes a brush (251) and a blade (252); and a control unit (300). The brush and the blade are disposed at a height at which the brush and the blade are able to come into contact with the nozzle, the brush and the blade have a melting point higher than a plasticizing temperature of the plasticizing material, and have hardness lower than hardness of the nozzle, in the cleaning processing, the control unit is configured to execute a cleaning operation of bringing at least one of the brush and the blade into contact with the nozzle by reciprocally moving the nozzle such that the nozzle cuts across the cleaning mechanism a plurality of times, and the control unit is configured to reciprocally move the nozzle such that the nozzle comes into contact with the brush or the blade at different positions in the cleaning operation.
