Title (EN) VALVED NOZZLE WITH A COMPENSATOR AND MASSIVELY PARALLEL 3D PRINTING SYSTEM
(FR) BUSE À SOUPAPE DOTÉE D'UN COMPENSATEUR ET SYSTÈME D'IMPRESSION 3D MASSIVEMENT PARALLÈLE
Abstract:
(EN) In one aspect, the present disclosure provides a nozzle for a 3D printing system. The nozzle may include a flowpath with a material inlet and a material outlet. The nozzle may further include a valve in fluid communication with the flowpath between the material inlet and the material outlet, where the valve includes a closed state and an open state, where in the closed state the valve obstructs the flowpath between the material inlet and the material outlet, and where in the open state the material inlet is in fluid communication with the material outlet. The nozzle may further include a compensator in fluid communication with the flowpath, where the compensator includes a contracted state associated with the open state of the valve and an expanded state associated with the closed state of the valve.
(FR) Selon un aspect, la présente invention concerne une buse pour un système d'impression 3D. La buse peut comprendre un trajet d'écoulement ayant une entrée de matériau et une sortie de matériau. La buse peut en outre comprendre une soupape en communication fluidique avec le trajet d'écoulement entre l'entrée de matériau et la sortie de matériau, la soupape comprenant un état fermé et un état ouvert. À l'état fermé, la soupape ferme le trajet d'écoulement entre l'entrée de matériau et la sortie de matériau, et à l'état ouvert, l'entrée de matériau est en communication fluidique avec la sortie de matériau. La buse peut en outre comprendre un compensateur en communication fluidique avec le trajet d'écoulement, le compensateur comprenant un état contracté associé à l'état ouvert de la soupape et un état dilaté associé à l'état fermé de la valve.
