Abstract
A three-dimensional shaping device includes: a dispensing unit including a nozzle; a stage having a shaping surface on which a shaping material is to be laminated; a position changing unit configured to change a relative position between the nozzle and the stage; a control unit configured to control the position changing unit; and a measurement module used to measure a difference of the nozzle from a reference position in the shaping surface based on a first position of the nozzle in the shaping surface and a second position of the nozzle in the shaping surface. The first position is a position in which the nozzle is assumed to be positioned by the control unit controlling the position changing unit. The second position is a position changed by the control unit controlling the position changing unit.
