Virtual designs into physical objects/Automated construction
Computer controlled flexible manufacturing methods can even be applied to constructing buildings. Contour Crafting is a technique that has been developed by the University of Southern California that involves building up the structure of the building in horizontal layers by squeezing out quick drying cement from a shaped nozzle. This is much like the 'fused deposition modelling' 3D printing method but on a huge scale.
The walls of these structures do not have to be straight and complex organic curved and domed buildings could easily be made, mimicking biological structures.
A house can be designed completely on computer, then the automated constructor sets to work with no human labour involved. The team developing this technology
