Claim 0:
1. A three-dimensional modeling device comprising:
a modeling unit having a nozzle ejecting a modeling material from a nozzle opening formed at a distal end surface;
a stage having a deposition surface where the modeling material is deposited;
a movement mechanism unit configured to change a relative position between the nozzle and the stage and configured to position a measuring unit to selectively face the distal end surface, the movement mechanism having an actuator and the measuring unit having a sensor;
a reference unit having a reference surface arranged at a position that corresponds to the deposition surface in an intersecting direction intersecting the deposition surface, the reference unit being separate from the nozzle; and
a control unit configured to control the modeling unit and the movement mechanism unit to model a three-dimensional modeled object,
the control unit
configured to control the movement mechanism to position the measuring unit to face the reference surface for the measuring unit to measure a first value that is a value about a distance between the measuring unit and the reference surface and control the movement mechanism unit to position the measuring unit to face the distal end surface for the measuring unit to measure a second value that is a value about a distance between the measuring unit and the distal end surface, and
configured to decide a distance between the distal end surface and the deposition surface for when modeling the three-dimensional modeled object, based on the first value and the second value.
