  • Filter element and method of manufacturing a filter element
    Patent number: 10765975
    Abstract: A filter element for the filtration of fluids can be manufactured from powdered metal using a laser manufacturing process. The powdered metal is deposited in a layer on fabrication platform and a laser beam is directed toward the layer of material so that the powdered metal granules fuse together to form a first component of the filter element. Successive layers of powdered metal can be deposited over the first component and also fused with the laser beam to form additional components. During the manufacturing process, the power or scan rate of the laser beam many be changed so that the formed layers of the filter element may have different porosity characteristics, for example, with certain portions being fluid permeable and other portions being fluid impermeable.
