From the below post i want to share with you all how well the solar energy is used to accomplish the task of printing in the sand to make some objects. Heading out to the desert and harnessing the power of the sun to make a 3D printer that can print objects out of sand. You?” “… catching up on Breaking Bad.” You know the kid in your old neighbourhood that spent his spare time frying ants with a magnifying glass? This is like that except instead of a magnifying glass, he’s using an big ol’ fresnel lens. And instead of roasting insects, he’s melting freaking sand into stuff.
Built by artist Markus Kayser, the “SolarSinter” concept isn’t too dissimilar from laser sintering printers used by operations like SpaceX to print otherwise impossible objects out of metal. A focused sun beam is a whole lot less precise than a finely-honed laser, of course — but the core concepts are the same.
