Title
(EN) OPTICAL HEAD FOR POWDER SPRAY 3D PRINTING
(FR) TÊTE OPTIQUE D'IMPRESSION 3D PAR PROJECTION DE POUDRE
Abstract
(EN)
The invention relates to a powder-dispensing head (1) for an additive manufacturing machine, the head (1) comprising: - a through-opening arranged to allow a high-energy beam to pass through it towards the melt point, - a body (2) comprising N powder feed ducts distributed at regular intervals around the through-opening and converging towards the melt point, the dispensing head (1) further comprising a dispensing member (3) comprising a powder-dispensing chamber having a powder inlet and N powder outlets distributed at regular intervals around the through-opening, the body (2) and the dispensing member (3) being configured to be able to move relative to each other, in order to fluidically connect or disconnect the powder outlets to the respective powder feed ducts depending on the relative position of the dispensing member (3) with respect to the body (2).
(FR)
L'invention porte sur une tête de distribution de poudres (1) pour machine de fabrication additive, ladite tête (1) comprenant: - une ouverture traversante agencée pour permettre un passage d'un faisceau à haute énergie vers le point de fusion, - un corps (2) comprenant N conduits d'amené de poudre régulièrement distribués autour de l'ouverture traversante et convergeant vers le point de fusion, la tête de distribution (1) comprenant en outre un organe de distribution (3) comprenant une chambre de distribution de poudre présentant une entrée de poudre et N sorties de poudre régulièrement distribuées autour de l'ouverture traversante, 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 les sorties de poudre aux conduits d'amené de poudre respectifs selon la position relative dudit organe de distribution (3) par rapport au corps (2).
