EVENTO: Brera Design District / Lomography
In the deserts of the world two elements dominate - sun and sand. The former offers a vast energy source of huge potential, the latter an almost unlimited supply of silica in the form of quartz. The experience of working in the desert with the Sun-Cutter led me directly to the idea of a new machine that could bring together these two elements. Silicia sand when heated to melting point and allowed to cool solidifies as glass. This process of converting a powdery substance via a heating process into a solid form is known as sintering and has in recent years become a central process in design prototyping known as 3D printing or SLS (selective laser sintering). These 3D printers use laser technology to create very precise 3D objects from a variety of powdered plastics, resins and metals - the objects being the exact physical counterparts of the computer-drawn 3D designs inputted by the designer. By using the sunâ€™s rays instead of a laser and sand instead of resins, I had the basis of an entirely new solar-powered machine and production process for making glass objects that taps into the abundant supplies of sun and sand to be found in the deserts of the world.
