Abstract
A three-dimensional modeling device includes a modeling section supplied with a material including a metal powder, a laser source adapted to emit a laser used to sinter or melt the metal powder, and an optical component through which the laser emitted from the laser source passes in the midway to the material on the modeling section. The optical component is provided with a first area, which faces to the modeling section, and through which the laser passes, and a second area higher in surface free energy than the first area is disposed in at least a part of a periphery of the first area.
