An American company says it has completed the first permitted 3D printed home in the United States. The home was shown to reporters and visitors at the South by Southwest technology conference and music festival. The event took place earlier this month in Austin, Texas. Building company ICON has developed large 3D printers that build homes with mortar, a hard and strong material. ICON uses robotics, computer software programs and advanced materials to make houses. Jason Ballard is the company’s co-founder. “So I’m standing in front of the first permitted 3D-printed home in America. This house was actually printed in high winds, blowing dust and rain.” It is important for the printing process to operate in extreme conditions, such as weather disasters. The goal is to print homes in developing countries.
