Title OPTICAL FABRICATION DEVICE meetings
Abstract An optical fabrication device for fabricating a structural member using one-photon absorption, the optical fabrication device comprising: a storage tank that stores liquid photocuring resin; a stage that is arranged inside the storage tank and is provided in such a way that the clearance between the stage and a bottom surface of the storage tank can be changed; and a first irradiation unit that irradiates light for curing the photocuring resin. A bottom part of the storage tank is a transmission window that transmits light. The first irradiation unit includes a first light source that emits light, a condensing optical system which is arranged on an optical path of light between the first light source and the transmission window, and in which a focal position is set at a position separated from a surface of the transmission window on the storage tank interior side, and a control unit that controls the output of the light emitted from the first light source. The control unit controls the output so that the light intensity of light at the surface falls below a threshold of light intensity at which the photocuring resin is cured.
