Solar Powered 3D Printer
Master candidate in Design Products at the Royal College of Art in London, Markus Kayser converted sunlight and sand into glass, which produced a fully automated, solar powered ‘solar sinter’ 3D printer. The machine uses replicator G open source software and works the same way as a common 3D printer would. The process of heating a powder, which in this case is silica sand, to its melting point and letting it cool and solidify into glass (in this case), powers the device to move automatically. ‘Solar Sinter’ uses sun rays, in place of a laser, to heat up the sand particles and by continually sweeping new sand over the previously melted down parts, Kayser built up a 3D product.
