3D printers are getting better and better. They tend to use materials like resin or ABS plastic, but what if the printers used two widely available resources in the desert, like sun and sand? Markus Kayser, a MA student at the Royal College of Art, has done just that. The “Solar-Sinter” is powered by the sun via two photovoltaic panels, and it focuses the sun’s rays to heat sand to its melting point so that it solidifies as glass when it cools. Then the fully automated device creates a glass object from a 3D computer design.
