Burkitt Posted June 25, 2011 Share Posted June 25, 2011 My Dad just sent me a link to this amazing article about a 3D printer which uses sand as the printing material, melting it with the sun focused by a lens: http://thisiscolossal.com/2011/06/markus-kayser-builds-a-solar-powered-3d-printer-that-prints-glass-from-sand-and-a-sun-powered-laser-cutter/ . There's a good video of it in action towards the bottom of the page. The resolution's a bit low for rolling stock, but perhaps it could be used to do some rather nice cliff face scenery complete with strata?
