Three-dimensional modeling device and method of manufacturing three-dimensional shaped article

A three-dimensional modeling device comprising:

• a plasticizing section configured to plasticize a material to generate a shaping material;
• a stage on which the shaping material is stacked;
• a nozzle which has a nozzle opening, and is configured to eject the shaping material from the nozzle opening toward a modeling area on the stage;
• a transfer mechanism section configured to change a relative position between the nozzle and the stage;
• a heating section having a heater and a heating member configured to heat the shaping material stacked in the modeling area with heat supplied from the heater;
• and
• an adjustment mechanism section configured to adjust, separately, a tilt of the heating member with respect to the stage in a first axial direction and a second axial direction, the first axial direction and the second axial direction being orthogonal to each other and the first axial direction and the second axial direction being orthogonal to a stacking direction of the shaping material, wherein
• the nozzle opening is located between the stage and the heating section in the stacking direction,
• the heating section is configured so that a relative position to the stage changes together with the nozzle,
• the heating member covers at least the modeling area when viewed along the stacking direction,
• the heating section is fixed to the plasticizing section via the adjustment mechanism section,
• the adjustment mechanism section includes a first member fixed to the transfer mechanism section, a second member provided with a first hole into which a first screw is inserted in the first axial direction and a second hole into which a pin is inserted in the first axial direction, the second member being fixed to the first member by the first screw, a third member provided with a third hole into which the pin is inserted in the first axial direction and a groove into which a second screw is inserted in the first axial direction, the third member being fixed to the second member by the pin and the second screw, and an arm connecting the heating section,
• the groove provided in the third member has a shape such that the third member rotates around the pin, the third member connecting the heating section via the arm,
• the second member is configured to adjust the tilt of the heating member with respect to the stage in the first axial direction by rotating the first screw, and
• the third member is configured to adjust the tilt of the heating member with respect to the stage in the second axial direction by rotating the third member around the pin.
