3D printers that can produce building materials are being investigated at the University of New South Wales in Australia with academics suggesting that 3D printing could reduce the costs of building homes. Some have concluded that using the technology, the cost of building materials for a 3D printed house Australia could be 75% less than those produced using traditional manufacturing processes.
There are, however, some challenges that need to be overcome before 3D printed buildings become commonplace. One of these is the size of some building components, such as glass framing systems. In addition, there are questions about whether the materials used by the printing process can match the strength of building components such as steel frames. Researchers say these problems are likely to be overcome in the near future with the current speed of technological development and that printed houses will soon become commonplace.
