Researchers have invented a 3D printer that runs on Sand and Sunlight!

Earth's natural resources are running out, and people are now forced to become more creative in finding new sources of energy and material.  Luckily, sand and sun are an abundant resource, and Marcus Kaiser is using them to their full potential!

Kaiser invented a solar sinter, a printer that uses sunlight and sand as raw energy to print 3-D objects made of glass.  High tech production technology has made the process possible, and has raised questions about how best to use sunlight: the earth's most abundant and efficient energy resource.
