Buildings Made with a Printer

Technology Review describes the work of Neri Oxman, an architect and professor at MIT's Media Lab, to 'print' complex structures using concrete, polymers and other materials.  Her work goes beyond initiatives such as "Robo-Brickie Builds a House in a Day" by varying the properties of the material, such as elasticity of a polymer or the porosity and strength of concrete.  Columns can be structured with dense concrete on the outside where stress is the greatest and lighter-weight concrete on the inside Porous or composite materials could be used in low-stress areas to allow additional light into buildings.
