A three-dimensionally laminated object modeling apparatus includes a cylinder configured to store a molten resin, a discharging nozzle that is communicated with the cylinder, and a piston configured to discharge the molten resin from the discharging nozzle by moving in a direction of approaching the discharging nozzle and by pressurizing the molten resin in the cylinder, and models a three-dimensionally modeled object by laminating a resin bead that is the molten resin discharged from the discharging nozzle on a table. It includes a drive device configured to relatively move the discharging nozzle with respect to the table and at least one processor configured to acquire a movement speed of the discharging nozzle and control movement of the piston based on the movement speed of the discharging nozzle.
