Abstract
This additive manufacturing device produces a molded object by laminate molding which involves: supplying a powder material to a build surface of an object to be molded; and fusing and hardening the supplied powder material through irradiating the powder material with a laser. The additive manufacturing device comprises: a main part having a stage on which the molded object is supported; a laser oscillation unit which generates a laser; an irradiation unit which irradiates the build surface with a laser and which is capable of varying the irradiation angle of the laser with respect to the build surface; and an output adjustment unit which is capable of adjusting the laser output on the basis of the area of laser irradiation on the build surface.
Claims10
An additive manufacturing device that supplies a powder material to a build surface of a molded article and performs laminate molding of the molded article by irradiating the supplied powder material with a laser to melt and cure the powder material, the additive manufacturing device comprising:
- a main part that includes a stage supporting the molded article;
- a laser oscillation unit that generates the laser;
- an irradiation unit that is capable of irradiating the build surface with the laser and changing an irradiation angle of the laser with respect to the build surface;
- and
- an output adjustment unit that is capable of adjusting an output of the laser based on an irradiation area of the laser on the build surface, wherein
- the output adjustment unit is capable of dividing the build surface into a plurality of sections using dividing lines having a shape of concentric circles centered on an irradiation point of the laser and setting the output of the laser different for each section.
(canceled)
An additive manufacturing method of generating a molded article by irradiating a powder material with a laser to melt and cure the powder material, the method comprising:
- a step of generating the laser;
- a step of irradiating a build surface on which the powder material is laid with the laser and changing an irradiation angle of the laser with respect to the build surface;
- a step of acquiring an irradiation area of the laser on the build surface;
- and
- a step of adjusting an output of the laser based on the irradiation area.
