3D Printed Houses

A couple in the Netherlands just became the people in Europe to move into a 3D-printed home. Experiments with this kind of home-building are cropping up around the world. Are they the future? Theo Salet, professor of structural design and concrete structures at Eindhoven University of Technology, was a part of the team that built this 3D printed house. (Photo credit: Bart van Overbeeke)
