Three-dimensional shaping system

A three-dimensional shaping system comprising:

• a dispensing unit including a plasticizing unit configured to plasticize a material to generate a plasticizing material and a nozzle configured to dispense the plasticizing material;
• a stage allowing the plasticizing material to be laminated;
• a moving unit configured to change a relative position between the nozzle and the stage;
• and
• a plate-shaped heating unit including a first heater configured to heat the plasticizing material laminated on the stage, the plate-shaped heating unit having a through hole formed therein, wherein
• at least a part of the nozzle is located in the through hole during shaping of a shaped object,
• the moving unit changes a position of the heating unit with respect to the stage in conjunction with a change in a position of the nozzle with respect to the stage,
• a part of at least one of the stage and the heating unit is made of a transparent material, and
• a detection unit configured to detect the shaped object on the stage via the transparent material, wherein the detection unit is disposed at least one of below the stage and above the heating unit.
