Claim 0:
1. A three-dimensional shaping device, comprising:
a stage having a shaping surface in which first and second grooves are provided, the first and second grooves extending along a first direction, each of the first and second grooves having an open end at one end and a closed end at the other end, the open ends being exposed to an outside of the stage, other parts of the stage existing between the closed ends and the outside of the stage;
a discharge head configured to supply a shaping material to the shaping surface;
a motor configured to relatively move the stage and the discharge head;
a heater configured to heat the stage;
a memory configured to store a program; and
a processor configures to execute the program to control the discharge head and the motor so as to:
form a first girder layer by supplying the shaping material into the first groove while relatively moving the discharge head in the first direction with respect to the stage;
form a second girder layer by supplying the shaping material into the second groove while relatively moving the discharge head in the first direction with respect to the stage;
form a first floor layer spanning the first girder layer and the second girder layer by supplying the shaping material onto the shaping surface and first and second girder layers while relatively moving the discharge head with respect to the stage;
form a three-dimensional object on the first floor layer by supplying the shaping material onto the first floor layer; and
cause the heater to heat the stage to make an entirety of the three-dimensional object, the first floor layer, and the first and second girder layers to slide out from the stage to the outside of the stage.
