Downloading Designs: Soon in 3D


A team of French scientists has developed a method of making flat shapes form themselves into 3D shapes by simply adding a drop of water in a carefully designed spot. Flower patterned shapes become spheres, a cross shape becomes a box. They envision manufacturing microscopic 3D structures like those used in ink jet printers and video projectors. We imagine downloading designs that print out and then fold themselves. ::New Scientist
