The world's first family to live in a 3D-printed home

SGT Wayne Wood thanks for the informative read/ share!

I would be interested to learn more about plumbing, electrical, and HVAC piping, ducting lines...where they go, how you add on or do updates, etc, with cement-filled walls. May be a good solution for 3rd world or any areas where housing development is not strictly controlled by government regulations.
