Embodiment Construction
[0013] A three-dimensional modeling apparatus according to one aspect of the present disclosure is configured to preheat the powder material by irradiating a charged particle beam to the powder material, and then irradiate the powder material with a charged particle beam to melt the powder material to shape a three-dimensional object. The three-dimensional modeling device includes: a beam emitting unit that emits a charged particle beam and irradiates the powder material with the charged particle beam; Detects where powdery material is scattered. When the powder material is scattered by the irradiation of the charged particle beam, the beam emitting unit irradiates the charged particle beam so as to increase the heating amount of the preheating at the scattered position. In this three-dimensional modeling device, when the powder material is scattered due to the irradiation of the charged particle beam, the heating amount of the preheating is increased at the position where the...

This three-dimensional shaping device shapes a three-dimensional object by preliminarily heating a powder material by irradiating same with an electron beam and fusing the powder material by further irradiating same with an electron beam. The three-dimensional shaping device is provided with: a beam emission part which emits an electron beam and irradiates a powder material with the electron beam;and a position detection part which, in the case when the powder material gets scattered upon being irradiated with the electron beam, detects the position of the scattered powder material. When thepower material gets scattered upon irradiation of an electron beam, the beam emission part performs electron beam irradiation in such a manner as to increase the level of preliminary heating at the position where the scattering occurred.
Description
technical field [0001] The present disclosure describes a three-dimensional modeling device and a three-dimensional modeling method for modeling a three-dimensional object. Background technique [0002] Conventionally, as a three-dimensional modeling device and a three-dimensional modeling method, for example, a device and a method described in US Pat. No. 8,992,816 are known. This apparatus and method molds a three-dimensional object by irradiating a powder material with an electron beam to melt and then solidify the powder material. Additionally, in the apparatus and method, a detector is provided near the surface of the powder material. This detector is used to detect scattering of powdery material generated when electron beams are irradiated. That is, the detector detects a phenomenon in which the powder material is scattered and smoky. Furthermore, in the apparatus and method, in the case where scattering of the powdery material is detected, the irradiation of the el...
