A Solar-Powered 3D Printer Prints Glass From Sand

Tx-0 writes in with a story in Colossal Art & Design. From the article: “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. … Next, Kayser began to examine the process of 3D printing. Merging two of the deserts most abundant resources, nearly unlimited quantities of sand and sun, he created the Solar Sinter, a device that melts sand to create 3D objects out of glass.”
