FYI - VERY BLEEDING EDGE technology. I watched a video today of building a 1750 sq ft home with a 3D printer. I was very skeptical when I heard about it, but when I watched the video it was amazing. Imagine a 3D printer that lays down a 2" ribbon of concrete mud. It draws the outline of the wall, then comes back with a 'Z' like cross piece between the wall sides. The it starts the next layer doing the same thing. No lumber, no laborers (except for those running the machine), no nothing, just mud. They had homes where they left the walls with the texture of the layers of a 3D printer, sort of like the 70's look of exposed slump block, and they had homes where someone came back after the layer was laid down and hit it with a trowel so you had a smooth wall.
Granted this is really the cutting edge of new technology, but imagine 10 years out.
They 'printed' this house in less than 24 hours. All the exterior walls, all the interior walls, all the doorways, all the window openings, just freaking amazing.
I have no idea what we're going to do with all those people streaming across our borders. There isn't going to be the laborer jobs at some point like there used to be.
Did they print the wiring in the walls, the windows, doors, and cabinets?
There is a hell of a lot more time spent putting the hvac, electrical, plumbing, and trim in a house than just framing it.
