Systems and methods for implementing node to node connections in mechanized assemblies
Techniques for joining nodes and subcomponents are presented herein. An additively manufactured first node or subcomponent has a groove. An additively manufactured second node or subcomponent has a tongue configured to extend into and mate with the groove to form a tongue-and-groove connection between the first and second node or subcomponent. In some aspects, the tongue-groove connection may extend substantially around a periphery of the node or subcomponent. In other aspects, a first subcomponent having a fluid pipe interface may be coupled via a tongue-groove connection to a second subcomponent having a fluid pipe interface, thereby enabling fluid to flow between subcomponents of the resulting integrated component.
