Lack of housing is a problem in many countries. The population of people is growing, but megacities are no longer able to meet the ever-growing demand. As the UN predicts, by 2015 there will be 9.2 billion people on Earth. And all of them will have to live somewhere. Fortunately, the problem of accommodating all these new tenants already has a solution.
Professor Berok Khoshnevis of Contour Crafting came up with a concept for a construction 3d printer that can print a 250 square meter house in just 24 hours. The printer consists of two movable beams and a print head. Fast-drying cement is used as a material, due to which such a speed of construction is achieved.
This does not mean that the "miracle printer" is capable of producing a completely finished home. The help of construction workers will also be needed for preparatory activities, laying communications and finishing the premises.
It should be noted that this is not the first idea to use 3D printers as a construction tool. So, NASA plans to use them to create spacecraft directly in orbit. There is even a project to develop a flying printer that will print the lunar base.
