Computational Design Tool Transforms Flat Materials Into 3-D Shapes
A new computational design tool can turn a flat sheet of plastic or metal into a complex 3-D shape, such as a mask, a sculpture or even a lady’s high-heel shoe. Researchers at Carnegie Mellon University and the Swiss Federal Institute of Technology in Lausanne, Switzerland (EPFL), say the tool enables designers to fully and creatively exploit an unusual quality of certain materials — the ability to expand uniformly in two dimensions. A rubber band, by contrast, contracts in one dimension while being stretched in another.
