3D printing technology to build home in a cost effective manner is gaining momentum in the last few years. With 3D printing, customized homes can be built at a rapid pace.
This article talks about Dr. Behrokh Khoshnevis' approach that:
"relies on mobile large-scale, lightweight 3D printers which can be transported to a job site quite easily. Once transported the machine is assembled and can begin constructing homes or other large structures, layer-by-layer, reducing the waste, cost, and time it takes to construct a building. Despite Khoshnevis’ early successes, he has remained relatively quiet over the last year or two in regards to the progress that is being made with his Contour Crafting technology.
Khoshnevis mentions that he has set up a company to commercialize the Contour Crafting technology and is currently approaching various applications. In fact, Khoshnevis and his company are making such rapid progress that he expects the very first printers to become available in the market within the next 1-2 years. Universities and research labs, however, may get access to these machines even sooner.
Once rolled out the machine will initially be put to use constructing smaller homes, and will be capable of printing exterior concrete walls, insulation, and even drywall.
