An additively manufactured node is disclosed. A node is an additively manufactured (AM) structure that includes a feature, e.g., a socket, a receptacle, etc., for accepting another structure, e.g., a tube, a panel, etc. An additively manufactured node can include a surface with an opening to a feed channel through the node. A second surface of the node can include with a plurality of openings to an array of outlet channels. Each of the outlet channels can extend through the node and can connect to the feed channel. Tortuous paths can be used between channels created by the node surface and adjacent structures as well as node interior surfaces. These tortuous paths can be tuned to allow for optimal fluid flow processes.
