Three-dimensional laminating and shaping apparatus, control method of three-dimensional laminating and shaping apparatus, and control program of three-dimensional laminating and shaping apparatus

A control method of a three-dimensional laminating and shaping apparatus including

• 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,
• wherein the three-dimensional laminated and shaped object is a joined member obtained by joining at least two kinds of materials,
• the method comprising:
• causing the controller to control the material supplier to form a graded composition of the materials in a boundary region of the three-dimensional laminated and shaped object.

A non-transitory computer readable medium storing a control program of a three-dimensional laminating and shaping apparatus including

• 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,
• wherein the three-dimensional laminated and shaped object is a joined member obtained by joining at least two kinds of materials,
• the program for causing a computer to execute a method, comprising:
• causing the controller to control the material supplier to form a graded composition of the materials in a boundary region of the three-dimensional laminated and shaped object.
