One of the challenges for over a billion people around the world is the cost of housing. Homes are difficult to construct, take lots of time, and can be very expensive. Behrokh Khoshnevis is a professor of Industrial & Systems Engineering and is the Director of Manufacturing Engineering Graduate Program at the University of Southern California (USC). The professor wants to use CAD/CAM technology to make it easier to build homes for those who cannot afford them.
Believe it or not, he argues that we can scale up 3-D printing to build entire neighborhoods with dignified housing at a fraction of the cost in a fraction of the time. This would be a huge step in the creation of affordable housing for much of the world.
