    Abstract: An optical processing nozzle that homogeneously supplies a fluid to a processing surface in optical processing is provided. The optical processing nozzle includes a beam path that is arranged so that a beam can pass through the beam path toward a processing surface in order to perform processing using a beam guided from a light source, and a channel structure that is arranged around the beam path and is configured to eject a fluid toward the processing surface. The channel structure includes an inflow port through which the fluid flows, at least two passage holes through which the fluid flowing from the inflow port passes, a channel that guides the fluid from the inflow port to the passage holes, and an ejection port from which the fluid having passed through the at least two passage holes is ejected toward the processing surface. The at least two passage holes are arranged to be spatially symmetrical with respect to the inflow port, and the ejection port is arranged to be spatially symmetrical with respect to the optical axis of a beam coming out from the beam path.

    Abstract translation: 提供了一种在光学处理中将流体均匀地供应到处理表面的光学加工喷嘴。 光学处理喷嘴包括光束路径，其布置成使得光束可以通过光束路径朝向处理表面，以便使用从光源引导的光束进行处理，以及布置在光束路径周围的通道结构 并且被配置为朝向处理表面喷射流体。 通道结构包括流体流过的流入口，流体从流入口流动的流体通过的至少两个通过孔，将流体从流入口引导到通道的通道， 已经通过至少两个通道孔的流体朝向处理表面喷出。 至少两个通孔设置成相对于流入口在空间上对称，并且喷射口被布置成相对于从光束路径出来的光束的光轴在空间上对称。

    Abstract: A three-dimensional deposition device and a three-dimensional deposition device method are provided. Included are: a powder passage (43) and a nozzle injection opening (45) that supply a powder (P) toward a working surface (91) of an object (90) to be processed; a laser path (44) that irradiates the powder (P) with a laser beam (L) to sinter or melt and solidify at least a part of the powder (P) irradiated with the laser beam (L) so as to form formed layers (151, 152, 153, and 154); a rotation table unit (17) serving as an irradiation angle changing unit that changes an irradiation angle (θ) of the laser beam (L) emitted from the laser path (44) to the working surface (91); and a controller (52) that controls the rotation table unit (17) so that the irradiation angle (θ) on an overhanging side with respect to the working surface (91) is less than 90° in a range in which the formed layers (151, 152, 153, and 154) can be formed.
