This ESA project took place at the DLR German Aerospace Center facility in Cologne, with a 3D printer table attached to a solar furnace, baking successive 0.1 mm layers of moondust at a temperature of 1000\u00b0C. A 20 x 10 x 3 cm brick for building can be completed in around five hours. DLR Cologne\u2019s solar furnace has two working setups: as a baseline, it uses 147 curved mirror facets to focus either actual sunlight into a high temperature beam, employed to melt together the grains of regolith. But this mode is weather dependent, so a solar simulator was subsequently employed as well \u2013 based on an array of xenon lamps more typically found in cinema projectors.&#8221;<\/p>\n<p>Video credit: ESA<\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Bricks have been 3D printed out of simulated moondust using concentrated sunlight.
