This means a small team of these robots could provide housing for a small community in record time, inexpensively, and potentially reducing the total energy required to construct each house. The nice thing about 3D printing, even for low income housing, companies would be able to use this process to contour unique floorplans easily. We wouldn’t necessarily need to make every house exactly the same to save on production.
Professor Khoshnevis did a Tedx Talk roughly a year ago to describe the process and talk about the Contour Crafting project.
