Markus Kayser Builds a Solar-Powered 3D Printer that Prints Glass from Sand and a Sun-Powered Cutter
Industrial designer and tinkerer Markus Kayser spent the better part of a year building and experimenting with two fantastic devices that harness the sun’s power in some of the world’s harshest climates. The first he calls a Sun Cutter, a low-tech light cutter that uses a large ball lens to focus the sun’s rays onto a surface that’s moved by a cam-guided system. As the surface moves under the magnified light it cuts 2D components like a laser. The project was tested for the first time in August 2010 in the Egyptian desert and Kayser used thin plywood to create the parts for a few pairs of pretty sweet shades. But he didn’t stop there. Next, Kayser began to examine the process of 3D printing. In mid-May the Solar Sinter was tested for a two week period in the deserts of Siwa, Egypt, resulting in the amazing footage above.
