Beschreibung
Zusammenfassung:	A three dimensional modeling method for fabricating a modeled object having a cavity therein is disclosed. The three dimensional modeling method includes modeling the modeled object with first powder, the modeled object including an opening connecting the cavity and an outside of the modeled object; filling the cavity with second powder from the opening; sintering the modeled object whose cavity has been filled with the second powder in the filling; and removing the second powder in the cavity from the opening.
