Episode Summary:
Housing affordability all over the world has been closely tied to traditional supply and demand equilibria. Nations with growing economies and growing populations need more housing, yet the combination of cost, land availability, regulatory and environmental considerations has resulted in a significant lag between the time that housing is needed in the time that it is built. In America, Freddie Mac has reported that the housing deficit in America increased 52% between 2018 and 2020. One solution to the problem may be 3D printing, with a new generation of very large footprint machines which in the future may collapse the cost of new housing while simultaneously increasing build speed.Access all episodes of This Week in Engineering on engineering.com TV along with all of our other series.
