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

Abstract

A three-dimensional laminated and shaped object having a graded composition is accurately shaped. A three-dimensional laminating and shaping apparatus for shaping a three-dimensional laminated and shaped object having a graded composition by laminating a plurality of kinds of materials includes a material supplier that supplies the materials while executing a scan, an irradiator that irradiates the materials with a beam, and a controller that controls the material supplier. The controller controls the material supplier to supply, to a predetermined scanning area of a material scanning area, a necessary amount of a predetermined material for laminating one layer of the three-dimensional laminated and shaped object at a predetermined number of times.

1 . A three-dimensional laminating and shaping apparatus for shaping a three-dimensional laminated and shaped object having a graded composition by laminating a plurality of kinds of materials, comprising:
 a material supplier that supplies the materials while executing a scan;   an irradiator that irradiates the materials with a beam; and   a controller that controls said material supplier,   wherein said controller controls said material supplier to supply, to a predetermined scanning area of a material scanning area, a necessary amount of a predetermined material for laminating one layer of the three-dimensional laminated and shaped object at a predetermined number of times,   
     
     
         2 . The three-dimensional laminating and shaping apparatus according to  claim 1 , wherein said irradiator adjusts a beam intensity based on the predetermined number of times. 
     
     
         3 . The three-dimensional laminating and shaping apparatus according to  claim 1 , wherein the beam is a laser beam. 
     
     
         4 . The three-dimensional laminating and shaping apparatus according to any one of  claims 1 , wherein the materials are metal powders. 
     
     
         5 . A control method of a three-dimensional laminating and shaping apparatus for shaping a three-dimensional laminated and shaped object having a graded composition by laminating a plurality of kinds of materials, the apparatus including
 a material supplier that supplies the materials while executing a scan,   an irradiator that irradiates the materials with a beam, and   a controller that controls the material supplier,   the method comprising:   causing the controller to control the material supplier to supply, to a predetermined scanning area of a scanning area of the material supplier, a necessary amount of a predetermined material for laminating one layer of the three-dimensional laminated and shaped object at a predetermined number of times.   
     
     
         6 . A non-transitory computer readable medium storing a control program of a three-dimensional laminating and shaping apparatus for shaping a three-dimensional laminated and shaped object having a graded composition by laminating a plurality of kinds of materials, the apparatus including
 a material supplier that supplies the materials while executing a scan,   an irradiator that irradiates the materials with a beam, and   a controller that controls the material supplier,   the program for causing a computer to execute a method, comprising:   causing the controller to control the material supplier to supply, to a predetermined scanning area of a scanning area of the material supplier, a necessary amount of a predetermined material for laminating one layer of the three-dimensional laminated and shaped object at a predetermined number of times.
