Abstract

La présente invention concerne un dispositif d'élimination de poudre qui réalise efficacement, avec une configuration simple, une opération d'élimination de matière pulvérulente n'ayant pas été utilisée pour former un objet façonné, provenant de chaque section de stockage. Le dispositif d'élimination de poudre est un dispositif d'élimination de poudre qui élimine une matière pulvérulente n'ayant pas été utilisée pour former un objet façonné dans un dispositif de mise en forme qui utilise la matière pulvérulente, le dispositif d'élimination de poudre étant pourvu : d'une première section de stockage et d'une seconde section de stockage dans lesquelles est temporairement stockée une matière pulvérulente n'ayant pas été utilisée pour former un objet façonné ; et un commutateur de sélection, qui comprend une soupape ayant un état ouvert ou un état fermé, et qui change l'état de la soupape afin de sélectionner une source d'évacuation de la matière pulvérulente stockée temporairement, parmi la première section de stockage et la seconde section de stockage.
