SOLAR 3D ‘Sand’ Printing, how cool is that!

3D printing is the build up of 3D objects from digital models, atom by atom. This is accomplished through additive processes in which successive layers of material are laid down under computer control, what is astonishing in this video is how Markus replaced the the traditional material stuff with sand and utilised the sun heat of Siwa desert in Egypt to instantly turn sand particles to glass. Eco-friendly manufacturing at its best 🙂
