Having a roof your head is a basic human need, but there are 1.2 billion people the world adequate housing. This may change thanks to a revolutionary, low-cost use 3D printers to construct houses. With 3D printing, materials are joined together or reinforced using a computer-controlled device to create a three-dimensional object. Two companies have joined forces to try and ease homelessness the world by building affordable homes using 3D printing. Tech company ICON has developed a method printing a one-floor, 60-square-meter house of cement a day for just $10,000. This is a fraction both the time and cost needed to build a similar construction using conventional methods.
ICON has teamed with the non-profit, international housing organization New Story. Together, they will start building homes developing countries. Their joint venture will see 100 new homes constructed El Salvador next year. New Story's co-founder Alexandria Lafci acknowledged that the 100 homes were just a drop the ocean. She said: "There are 100 million people living slum conditions, in what we call survival mode." She also saw possibilities for 3D-printed houses to become common richer countries in years to come. However, she said that the moment: "The tech is ready now to print very high-quality, safe homes the places we're building."
