An Italian company has just exhibited an exciting concept of a 3D printer. It demonstrated a smaller version, but they believe they can build structures up to 3 meters tall.

“We will print a mixture made of clay and sand,” CEO Massimo Moretti said leading up to the event. “It takes weeks to print a real house, so we will print a smaller building because we only have two days. But the print, the mixture and materials have been already tested and they’re working.”

It opens up a world of possibilities. I really like the concept as it creates a opportunity to insulate the thermal mass of the earth by using air gaps. Alternatively the voids could be filled to create more thermal mass. It also fits in nicely with open source architecture.
