The Crane WASP, also known as "the infinity 3D printer," uses locally sourced clay, mud or cement to 3D-print affordable homes. It can even use agricultural waste as aggregate. The system is now being used to build much-needed housing in Colombia.
Wild theory time. I wonder how modular the piping/wiring could be made. With the right material (or technique) they could pause the print at various levels to do horizontal piping/wiring (or just put in conduit) and there’s plenty of room in the infill to do vertical - joining the horizontal and vertical might need something new. Everything is going to be cadded up beforehand and presumably the material is going to be consistent. With the right fittings maybe the plumping snaps together and the wiring comes in precut lengths. (Am in UK, most houses are made from concrete blocks that need to be tracked for wiring/plumbing - not sure how much difference this makes).
