Solar-Sinter 3D printer creates glass objects from sun and sand

Solar-Sinter 3D printer creates glass objects from sun and sand: "We've seen a growing number 3D printers that use additive manufacturing technology to form objects one layer at a time, usually from resin or ABS plastic. But Markus Kayser, an MA student at the Royal College of Art in London, has created a 3D printer that creates 3D objects using two things found in abundance in the desert - sun and sand."
