Claim 0:
1. A lamination molding apparatus, comprising:
an irradiator irradiating a material layer with a beam to form a solidified layer, wherein the material layer is formed for each of a plurality of divided layers obtained by dividing a desired three-dimensional molded object at a predetermined height in a molding region; and
a temperature adjustment device configured to abut against a part or all of a solidified body, which comprises an upper surface of the solidified body that is formed by laminating the solidified layer, and to heat and cool the part or all of the solidified body to a set temperature, wherein
the temperature adjustment device comprises:
a temperature adjustment plate which is heated and cooled to the set temperature;
a revolving portion configured to revolve the temperature adjustment plate between an upright state in which the temperature adjustment plate stands upright along a vertical direction and a lying state in which the temperature adjustment plate lies down along a horizontal direction; and
a back surface attachment portion and a lower attachment portion connecting the temperature adjustment plate and the revolving portion, wherein
the revolving portion is configured to set the temperature adjustment plate to the upright state when the part or all of the solidified body comprising the upper surface of the solidified body is not heated and cooled by the temperature adjustment device, and to set the temperature adjustment plate to the lying state when the part or all of the solidified body comprising the upper surface of the solidified body is heated and cooled by the temperature adjustment device, wherein
the back surface attachment portion comprises a ball joint fixed to a central position of a back surface of the temperature adjustment plate,
a lower end of the lower attachment portion comprises a pair of support columns fixed to a rotation shaft of the revolving portion, a connection member connecting upper ends of the pair of support columns, and a receiving piece connected to the ball joint provided at a central position of the connection member, wherein
an abutting surface formed between the ball joint and the receiving piece is slidable, and the temperature adjustment plate and the revolving portion are connected only by a connection structure of the ball joint and the receiving piece.
