Abstract

An object is to improve the shaping accuracy in three-dimensional shaping that forms a three-dimensional shaped object by repeating a formation process of fusing powder and solidifying the fused powder and a cutting process. A three-dimensional shaping apparatus of a powder bed system irradiates metal powder with laser to fuse the powder, solidifies the fused powder to form a thin layer, and stacks the formed thin layers to achieve three-dimensional shaping. The three-dimensional shaping apparatus cuts layers that have been formed every time a predetermined number of layers, for example, ten layers, are formed, with a view to improving the shaping accuracy of a shaped object. A shape S3, which is obtained by reflecting a displacement d1 between a target shape S1 to be obtained and a shape S2 including prediction of a deformation by a simulation, onto the target shape S1, is used as cutting data that defines a shape to be cut. A shape S5, which is obtained by reflecting a displacement d2 between the shape S1 and a shape including prediction of a further deformation, onto the shape S3, may be used as the cutting data. Performing the shaping and the cutting by using the cutting data generated based on the prediction of a deformation as described above improves the shaping accuracy of the shaped object.
