3D printed houses aren’t anything new; but still on the cusps of practicality. Hadrian X has created a robot that can cut and lay the bricks of a 3 bedroom 2 bath house in 2 days; working around the clock and in all weather conditions. Limitations still appear to be that this just places bricks – it doesn’t seem to do electrical, plumbing, ducts, initial foundation/etc. But this is just one more step forward into complete automation of construction. Likely something we’ll see by the end of our lifetimes.
