Title (EN) FILTER ELEMENT AND METHOD OF MANUFACTURING A FILTER ELEMENT
(FR) ELÉMENT FILTRANT ET PROCÉDÉ DE FABRICATION DE L'ÉLÉMENT FILTRANT
Abstract:
(EN) A filter element (102) for the filtration of fluids can be manufactured from powdered metal (220) using a laser manufacturing process (201). The powdered metal (220) is deposited in a layer on fabrication platform (210) and a laser beam (242) is directed toward the layer (230) of material so that the powdered metal granules fuse together to form a first component (232) of the filter element (102). Successive layers (250) of powdered metal (220) can be deposited over the first component (232) and also fused with the laser beam to form additional components (252). During the manufacturing process (201), the power or scan rate of the laser beam (242) many be changed so that the formed layers of the filter element (102) may have different porosity characteristics, for example, with certain portions being fluid permeable and other portions being fluid impermeable.
(FR) Un élément filtrant (102) pour la filtration de fluides peut être fabriqué à partir de métal en poudre (220) à l'aide d'un procédé de fabrication au laser (201). Le métal en poudre (220) est déposé dans une couche sur la plateforme de fabrication (210) et un faisceau laser (242) est dirigé vers la couche (230) de matériau de sorte que les granules de métal en poudre fusionnent pour former un premier composant (232) de l'élément filtrant (102). Des couches successives (250) de métal en poudre (220) peuvent être déposées sur le premier composant (232) et également fusionnées avec à l'aide du faisceau laser pour former des composants supplémentaires (252). Pendant le processus de fabrication (201), la puissance ou la fréquence de balayage du faisceau laser (242) peut être modifiée de sorte que les couches formées de l'élément filtrant (102) peuvent présenter des caractéristiques de porosité différentes, par exemple, certaines parties étant perméables aux fluides et d'autres parties étant imperméables aux fluides.
