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.

She is also developing software that takes into account design constraints and stress analysis to optimize materials usage and incorporate new functions. One of her works, a chaise lounge called Beast displayed at the Museum of Science (Boston) in 2010, "adjusts its shape, flexibility and softness to fit each person who sits in it. Made from eight materials of varying flexibility, it hugs your body, reacting to each movement". The design takes into account the shape of a human body as well as the distribution of pressure points to develop a complex structure that provides both compliance and support.
