Claim 0:
1. A method for manufacturing an additively-manufactured object in which deposition is performed by melting and solidifying a metal depending on three-dimensional shape data of a target shape, the method comprising:
[S1] acquiring the three-dimensional shape data;
[S2] creating a deposition plan in which a formation track in which each layer obtained by slicing a shape of the three-dimensional shape data is formed by the metal and a heating condition of the metal are determined;
[S3] determining a difference between a shape of the additively-manufactured object that thermally contracts by cooling to a room temperature after deposition and a shape of the three-dimensional shape data by an operation in a case where the additively-manufactured object is built by the deposition plan;
[S4] determining a modification shape model having a shape which considers the difference so that the shape of the additively-manufactured object after additive manufacturing and thermal contraction becomes the shape of the three-dimensional shape data;
[S5] creating a modified deposition plan that defines a formation track in which each layer obtained by slicing the shape of the modification shape model and the heating condition;
[S6] determining a difference between a shape of the additively-manufactured object that thermally contracts by cooling after deposition and the shape of the three-dimensional shape data by an operation in a case where the additively-manufactured object is built by the modified deposition plan;
[S7] repeating the above steps [S4] through [S6] until the difference falls within a predetermined allowable range; and
additively manufacturing the additively-manufactured object based on the modified deposition plan in which the difference falls within the allowable range.
