Abstract
A three-dimensional additive manufacturing device, which performs additive manufacturing by irradiating, with a beam, a powder bed laid on a build surface area, includes a projection unit that is configured to project a pattern in which there is a luminance distribution in the build surface area and the luminance distribution changes over time, an imaging unit configured to image the pattern projected onto the build surface area, and a reflective part configured to reflect at least one among a first light beam projected by the projection unit and a second light beam captured by the imaging unit. The projection and imaging units are disposed outside the chamber where the additive manufacturing is performed on the build surface area. The reflective part is accommodated inside the chamber. The first and second light beams pass through one first window portion installed on the chamber.
