The Dutch city of Eindhoven is to be the first in the world to have habitable homes made by a 3D printer, in an innovation its backers believe will revolutionise the construction industry. Of the first five new houses to be put on the rental market next year, the smallest, with two bedrooms, has already attracted applications from 20 interested families just a week after images were made available. Known as Project Milestone, the development is said by the Dutch construction company Van Wijnen to offer a solution to a shortage of skilled bricklayers in the Netherlands. The method will also cut costs and environmental damage by reducing the amount of cement that is used, said Rudy van Gurp, a manager at the firm, which is working in collaboration on the project with the Eindhoven University of Technology.
