In 2012, six single-family homes were made by a 3D printer in China. The inventor of that technology is now working on a 3D printer designed to construct buildings on Mars. Does this technology have a future on Earth? Or does the future of homebuilding involve modern factories that leverage robots to build wood or steel framing similar to the types of machines you might find in modern automotive plants? In the fifth episode of a series on the future of homebuilding, Andrew speaks with innovators and academics about technologies that have the potential to revolutionize the homebuilding industry, including interviews with Behrokh Khoshnevis, inventor of Contour Crafting; Professor Jeffrey Liker, author of The Toyota Way; and Michele Francovigh, Lead Project Engineer at Fincantieri.
