1. A manufacturing method of a three-dimensional object, comprising:
a positioning step of placing a fixing plate, which has a first surface and a second surface opposite to each other and in which a plurality of adhesive injection holes that are through holes are formed in a plate thickness direction, on a thin plate with a thickness of 1 mm or less, and positioning the thin plate to a predetermined position on the first surface of the fixing plate;
an adhering step of, after the positioning step, dripping an adhesive into the adhesive injection holes from a side close to the second surface and solidifying the adhesive in the adhesive injection holes to form a plurality of adhesive layers in the adhesive injection holes in order to adhere the first surface of the fixing plate to the thin plate;
a placing step of, after the adhering step, fixing the fixing plate and the thin plate onto a build table configured to be movable in a vertical direction of an additive manufacturing apparatus at a position with the thin plate on top;
an additive manufacturing step of, after the placing step, forming a plurality of solidified layers consisting of a build material on the thin plate by the additive manufacturing apparatus, and forming the three-dimensional object in which the thin plate and the solidified layers are integrated; and
a detaching step of, after the additive manufacturing step, taking out the fixing plate and the three-dimensional object from the additive manufacturing apparatus, and removing adhesion between the thin plate and the fixing plate by using a removing agent corresponding to the adhesive.
