Abstract
A three-dimensional object is manufactured by filling and hardening a powder material around a core. A powder material is first filled and layered around the core, and a beam is then selectively irradiated on the layer of powder material to form a hardened layer united with the core. These steps are repeated to form a plurality of hardened layers around the core, thereby manufacturing the three-dimensional object having the core embedded therein.
