PROBLEM TO BE SOLVED: To efficiently remove powder adhered on a taken-out stereoscopic molding.SOLUTION: A powder removal device includes jetting means 401 configured to jet, to a stereoscopic molding 300, air flow 403 including powder 20 used to mold the stereoscopic molding 300. Through jetting the air flow 403 including the powder 20, unsolidified powder 20 adhered onto the stereoscopic molding 300 can be removed, and even if the jetted powder 20 is adhered onto the stereoscopic molding 300 and sintered when sintering the stereoscopic molding 300, physical properties of the stereoscopic molding 300 after sintering will not be changed.SELECTED DRAWING: Figure 6 |
