Title
(FR) TETE D’IMPRESSION 3D PAR PROJECTION DE POUDRE
Abstract
(FR)
TETE D’IMPRESSION 3D PAR PROJECTION DE POUDRE L’invention porte sur une tête de distribution de poudres (1) pour machine de fabrication additive, ladite tête (1) comprenant : - un corps (2) comprenant un conduit d’amené de poudre vers un point de fusion, - une ouverture traversante agencée pour permettre un passage d’un faisceau à haute énergie vers le point de fusion, ladite tête de distribution (1) comprend en outre un organe de distribution (3) comprenant une chambre de distribution de poudre présentant une entrée de poudre et au moins une sortie de poudre, le corps (2) et l’organe de distribution (3) étant configurés pour être mobiles l’un par rapport à l’autre, pour connecter ou déconnecter fluidiquement la sortie de poudre au conduit d’amené de poudre selon la position relative dudit organe de distribution (3) par rapport au corps (2). L’invention porte également sur une imprimante 3D comprenant cette tête. Figure pour l'abrégé : Figure 2
