Systems and methods for implementing node to node connections in mechanized assemblies

An apparatus, comprising:

• an additively manufactured first subcomponent comprising a first outer wall and a first fluid pipe interface adjacent an edge of the first outer wall, the first fluid pipe interface comprising a first casing including a tongue structure extending outward relative to the edge of the first outer wall;
• and
• an additively manufactured second subcomponent comprising a second outer wall and a second fluid pipe interface adjacent an edge of the second outer wall, the second fluid pipe interface comprising a second casing including a respective groove structure positioned to receive the tongue structure when the first and second subcomponents are joined,
• wherein the first and second fluid pipe interfaces are sealed flush via a connection between the tongue-and-groove structures to enable fluid to flow between subcomponents.
