Abstract
A method of manufacturing a hydraulic valve component using additive manufacturing includes laying successive layers to form a flow aperture for a hydraulic valve component, and creating a lattice or mesh structure that at least partially defines the flow aperture of the hydraulic valve component, or a feature that forms an undercut along a direction that is parallel to a flow direction of the flow aperture, or a flow aperture having a size varying along a circumferential direction of the valve component.
