Embodiment approach 1
[0024] figure 1 It is a figure which shows the schematic structure of the additive manufacturing apparatus concerning Embodiment 1 of this invention. The additive manufacturing device 1 is a working machine that manufactures a molded object by laminating molten materials. The additive manufacturing apparatus 1 performs additive manufacturing by arc welding and beam irradiation.
[0025] The additive manufacturing apparatus 1 supplies a material, that is, a wire 6 to a workpiece, and laminates a bead made of molten material on a base material 18 . The additive manufacturing device 1 forms a shape 19 on the base material 18 by laminating beads on the base material 18 . The base material 18 is placed on the stage 20 . In Embodiment 1, the workpiece is an object of additively fused material, and refers to the base material 18 and the molded object 19 . figure 1 The illustrated substrate 18 is a sheet material. Substrate 18 may also be an object other than a sheet.

Embodiment approach 2
[0058] Image 6 It is a figure for demonstrating the operation|movement of the additive manufacturing apparatus concerning Embodiment 2 of this invention. Figure 7 It is a figure for demonstrating the supply of the wire rod in the additive manufacturing apparatus concerning Embodiment 2. In the second embodiment, the operation of the additive manufacturing device 1 will be described with reference to the configuration of the additive manufacturing device 1 according to the above-mentioned first embodiment.
[0059] exist Image 6 Changes related to each of the voltage applied between the wire 6 and the workpiece, the current flowing through the wire 6 , the wire speed, and the laser output are shown. The wire speed is the speed at which the wire 6 is sent out. The laser output is the output of the laser beam 5 involved in the laser oscillator 2 . exist Figure 7 shows from Image 6 Changes in the state of the wire rod 6 from time T2 to time T6 among the times T1 to T6 s...
Embodiment approach 3
[0068] Figure 8 It is a side view of the machining head included in the additive manufacturing apparatus according to Embodiment 3 of the present invention. Figure 9 is viewed from above Figure 8 A diagram showing the feed position and irradiation position for the case of the processing head. The additive manufacturing apparatus 1 according to Embodiment 3 can move the irradiation position of the laser beam 5 in the circumferential direction of a circle centered on the supply position of the wire 6 . In Embodiment 3, the same reference numerals are attached to the same constituent elements as in Embodiments 1 and 2 described above, and the configurations that are different from Embodiments 1 and 2 will be mainly described. exist Figure 9 In , the cross section of the wire 6 supplied to the supply position and the point of the laser beam 5 at the irradiation position are shown.
[0069] The machining head 61 has a beam nozzle 62 that emits the laser beam 5 toward the wo...
