This entire three-bedroom house was 3D printed using liquid concrete in just 12 hours.<br /><br />The 1200sqft build was unveiled to the new homeowner April Springfield and her 13-year-old son this month in Williamsburg, Virginia, USA.<br /><br />It took just 12-hours to print the concrete foundations of the three-bed, two-bath property, which would nominally take four weeks.<br /><br />Using concrete as its primary material can cut building the cost of building by up to 15% per square foot.<br /><br />It is also a great insulator so lowers heating and cooling bills, and its strength provides great protection against tornadoes and hurricanes. <br /><br />The building is also EarthCraft certified, meaning it minimizes environmental impacts and will not cost as much to maintain.<br /><br />April has supervised the laundry facilities at a local hotel for nearly five years, but her income is still less than 80% of the area median income.<br /><br />This has made it difficult to save enough to become a homeowner, but she used at least 300 hours of 'sweat equity' building the house herself to subsidise the cost.<br /><br />The project was organised by charity Habitat for Humanity in partnership with 3D-printing company Alquist.<br /><br />The Habitat Homebuyer Programme has offered April a mortgage with repayments of no more than 30% of her income, and puts money back into the community to build more affordable homes in the US.<br /><br />Construction of each home built by Habitat for Humanity Peninsula and Greater Williamsburg is a cooperative effort between volunteers, house sponsors and the buyers.<br /><br />April has also got her own personal 3D printer allowing her to reprint anything from electrical outlets to door knobs.<br /><br />This is the non-profit's first 3D-printed home, but expect to unveil their second in Tempe, Arizona, next month.<br /><br />Shot within January 2022.
