“So what are you doing this weekend, Markus?”

“Oh, you know. 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 neighborhood 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 disimmilar 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.

I bet this guy could make a mean sand castle.
