Janjaap Ruijssenaars' design can be printed from the sand "by pressing enter." But this change to high speed building positive?

3D printing may have been used for a long time in the world of architecture, which allows visionaries to discuss forms of increasingly complex and unbuildable in ether. But the technology has never been used to build something bigger than a prototype.

That could be changing now that the Dutch architect Janjaap Ruijssenaars 3D drawings revealed for the first printed at home. The House of the landscape takes the form of a continuous loop M?bius strip, which comes from the earth before falling over himself in a transparent corrugated. Its complex geometries are not pouring concrete, however, but the sand layers printed.

working with mathematician and artist Ruijssenaars plans to create the building up to 6x9m sections printed with D-Shape printer. Powered by Enrico Dini Italian engineer, the printer uses the same principles of stereolithography as small printers, only expanded using molding sand with a chemical bond. The sections can be printed like empty shells which are then filled with concrete reinforced by strength fibers. The whole house will take about 18 months to build, at an estimated cost of € 4-5m (? 3.3 ? 4.2 million).

"To build a complex concave-convex surface, for example, require formwork and prefabricated cage expensive and complicated scaffolding and manual casting," says Dini. Affirms D-Shape allows precision level unprecedented in the past. "limits of human developers and builders no longer obstruct the visions of architects."

Landscape House follows a project led by the Italian architect Andrea Morgante of Shiro Studio, which uses the same printer for the construction of a pavilion 3 m high in 2009 -. The largest object ever 3D printed in time
