3D Concrete Printing developed at Loughborough University is capable of producing large scale additive manufacturing, has the potential for producing full scale building components.
A demonstration of 3D construction using Contour Crafting where a robotic arm excretes clay or concrete and a metal guide is used to form walls that include a corrugated internal structure for strength. Because the walls are hollow, they have excellent insulating properties. Using Contour Crafting the shell of a 2,000 sq. ft. house, including floors, ceiling and roof, can be built in less than 20 hours custom designed on site.
