A method of manufacturing a laminate-molded object, comprising: acquiring shape data representing the shape of a shaped object; dividing the shaped object into a plurality of parallel layers based on the shape data and generating layer shape data representing the shape of each layer; and providing a control device; the method being characterized by achieving the following steps under the control of the control device: forming a melt bead of each layer and laminating the melt bead until the shape of the shaped object is formed, wherein the formation of the melt bead of each layer includes: forming the melt bead by a laminating device based on the layer shape data of each layer; measuring the height of the formed melt bead; comparing whether the measured height of the melt bead is within a range of a tolerance with respect to a planned height; forming another melt bead over the melt bead when the height of the melt bead is lower than a value obtained by subtracting the tolerance with respect to the planned height; and removing the melt bead when the height of the melt bead is higher than a value obtained by adding the tolerance to the planned height, wherein the forming of the melt bead and the removing of the melt bead are performed by an articulated welding robot and an articulated cutting robot, respectively. acquiring shape data representing the shape of a shaped object; dividing the shaped object into a plurality of parallel layers based on the shape data and generating layer shape data representing the shape of each layer; and providing a control device; the method being characterized by achieving the following steps under the control of the control device: forming a melt bead of each layer and laminating the melt bead until the shape of the shaped object is formed, wherein the formation of the melt bead of each layer includes: forming the melt bead by a laminating device based on the layer shape data of each layer; measuring the height of the formed melt bead; comparing whether the measured height of the melt bead is within a range of a tolerance with respect to a planned height; forming another melt bead over the melt bead when the height of the melt bead is lower than a value obtained by subtracting the tolerance with respect to the planned height; and removing the melt bead when the height of the melt bead is higher than a value obtained by adding the tolerance to the planned height, wherein the forming of the melt bead and the removing of the melt bead are performed by an articulated welding robot and an articulated cutting robot, respectively. forming a melt bead of each layer and laminating the melt bead until the shape of the shaped object is formed, wherein the formation of the melt bead of each layer includes: forming the melt bead by a laminating device based on the layer shape data of each layer; measuring the height of the formed melt bead; comparing whether the measured height of the melt bead is within a range of a tolerance with respect to a planned height; forming another melt bead over the melt bead when the height of the melt bead is lower than a value obtained by subtracting the tolerance with respect to the planned height; and removing the melt bead when the height of the melt bead is higher than a value obtained by adding the tolerance to the planned height, wherein forming the melt bead by a laminating device based on the layer shape data of each layer; measuring the height of the formed melt bead; comparing whether the measured height of the melt bead is within a range of a tolerance with respect to a planned height; forming another melt bead over the melt bead when the height of the melt bead is lower than a value obtained by subtracting the tolerance with respect to the planned height; and removing the melt bead when the height of the melt bead is higher than a value obtained by adding the tolerance to the planned height, wherein the forming of the melt bead and the removing of the melt bead are performed by an articulated welding robot and an articulated cutting robot, respectively.
