To create Digital Grotesque, Hansmeyer and Dillenburger first relinquished some control of the project to math. The duo used algorithms to let computers randomly design the room, which was printed in Zurich. (The team designed an overarching model, but many of the details are the work of algorithms.) With a digital version of the room in hand, they used sand as the material, along with a binding agent, to print large chunks of the room--up to 4 meters tall by 1 meter wide by 2 meters deep. After that, they assembled the room piece by piece from the sandstone material. The entire process took one year to design, one month to print, and one day to assemble.
