Africa, Sub-Saharan area. Year 2100.
Population growth and increased use of renewable energy have transformed a neglected area known as the Third World into one of the cornerstones of the economy and world energy support. The Sahara is and will be the lung of the world; not only because it produces a zero-emission energy, but especially because it is turning into one of the largest green areas of the planet. Desertification has been stopped and the ongoing challenge is to fight it, face it and cancel it. All this has led to the birth and growth of great metropolis in Sahel, like Ouagadougou, capital of Burkina Faso. A challenge for man and the world itself.

Printed Cities - D-Shape building
In 2014 the system of “D-Shape” printing was made up of a lattice-structured machine and a sliding component consisting of dozens of nozzles placed 2cm apart connected to a tank. The printing process consisted in putting a 5mm layer of sand and salt in the area destined for printing and subsequently setting in motion the sliding head containing the nozzles that sprayed a liquid that reacted with the sand and salt mixture, solidifying it. This process was activated by software, so once the 3d object was designed it was enough to start up the machine to produce layer upon layer of the desired object. Each 5mm layer took about 4.5 minutes to print but it would shortly be reduced to around 40 seconds. There was another machine that had only one nozzle. Today in 2100, skyscrapers hundreds of metres high are printed, 3d printing is needed to create many things and components in thousands of different materials.
