Abstract
A three-dimensional modeling device and a method for manufacturing a three-dimensional object are capable of heating layers of modeling material stacked in a modeling area through simple control, and stacking a new layer of modeling material on the heated layer of modeling material to form a three-dimensional object. The three-dimensional modeling device comprises: a plasticizing unit that plasticizes the material to generate modeling material; a stage for stacking the modeling material; a nozzle having a nozzle opening that ejects the modeling material from the nozzle opening toward the modeling area on the stage; a moving mechanism that can change the relative position of the nozzle and the stage; and a heating unit having a heater and a heating element that heats the modeling material stacked in the modeling area using heat supplied from the heater. The nozzle opening is located between the stage and the heating unit in the stacking direction of the modeling material, and the heating unit is configured to change its relative position with the stage together with the nozzle, and the heating element covers at least the modeling area when viewed along the stacking direction.
