“Printed Physics” looks at those technologi- cal and economical developments with which the physical characteristics of materials can be symbolically programmed, for example in the field of photovoltaics or in electronics more generally. These devices are already being industrially produced by a printing pro- cedure. It is no exaggeration to call this a modern printing revolution, although, unlike in Gutenberg’s day, the printed product does not represent anything but instead is itself functionally operative. This book is the first volume of the “Applied Virtuality” book series based on the meta- lithicum conferences organized twice a year by the Laboratory of Applied Virtuality CAAD at the Swiss Federal Institute of Technology ETH Zu?rich, where distinguished personali- ties from a broad range of architecture- related fields come together to discuss par- ticular technological developments that are economically significant and philosophically interesting.
