Abstract: A dissimilar material joined three-dimensional laminated and shaped object is shaped using a three-dimensional laminating and shaping apparatus. The three-dimensional laminating and shaping apparatus includes a material supplier that supplies materials of a three-dimensional laminated and shaped object to a shaping surface, an irradiator that irradiates the materials with a light beam, and a controller that controls the material supplier. The three-dimensional laminated and shaped object is a joined member obtained by joining dissimilar materials. The controller controls the material supplier to form a graded composition of the materials in a boundary region between the dissimilar materials of the three-dimensional laminated and shaped object.
