Title (EN) MOVING POWDER IN A 3D PRINTING SYSTEM
(FR) POUDRE MOBILE DANS UN SYSTÈME D'IMPRESSION 3D
Abstract:
(EN) In an example implementation, a powder metering device to move powder in a 3D printing system includes a rotor comprising a central hub and peripheral wheel to rotate about a shaft. Compartments are formed between the hub and the wheel by a plurality of fins that emanate from the hub at first fin ends and affix to the wheel at second fin ends. A top and bottom disk each have a planar surface to lie flush against and to seal, respectively, top and bottom perimeters of each compartment as the compartments rotate about the shaft between a powder receiving position and a powder dispensing position.
(FR) Dans un exemple de mode de réalisation, un dispositif de dosage de poudre pour déplacer une poudre dans un système d'impression 3D comprend un rotor comprenant un moyeu central et une roue périphérique destinée à tourner autour d'un arbre. Des compartiments sont formés entre le moyeu et la roue par une pluralité d'ailettes qui émanent du moyeu au niveau de premières extrémités d'ailette et se fixent à la roue au niveau de deuxièmes extrémités d'ailette. Un disque supérieur et un disque inférieur présentent chacun une surface plane pour affleurer et pour sceller, respectivement, des périmètres supérieur et inférieur de chaque compartiment lorsque les compartiments tournent autour de l'arbre entre une position de réception de poudre et une position de distribution de poudre.
