Abstract
A three-dimensional modeling device includes a modeling unit having a nozzle configured to eject a modeling material, a stage, a movement mechanism unit for changing a relative position between the nozzle and the stage, a measuring unit, a reference unit having a reference surface arranged at a position that corresponds to a deposition surface of the stage in an intersecting direction and where the reference surface can face the measuring unit, the reference unit being separate from the nozzle, and a control unit controlling the modeling unit and the movement mechanism unit. The control unit controls the measuring unit to measure a first distance between the measuring unit and the reference surface and a second distance between the measuring unit and the distal end surface, and decides a distance between a distal end surface of the nozzle and the deposition surface, based on the first and second distances.
