How Nantes team's 3-D printing may alter shape of homes to come
For some months now, a 3D printed house in Nantes has drawn lots of attention, not just because a printer was involved but also because it went up from start to finish so quickly (54 hours to print, then add some more time for the windows and roof). Interesting Engineering said it took some more time to add the roof, windows and doors.
A robot printer was used to print layers from the floor upwards to form the walls, and videos show a beautiful result of five rooms with rounded walls.
Now comes the latest news of the world's first family to move into a 3D-printed home—that is now home for the Ramdani family, consisting of the two parents and their 3 children, to enjoy life in the 4-bedroom house in Nantes, France.
The innovator behind this is project leader Benoit Furet, a professor at Nantes University. In a BBC report, Furet discussed costs.
BBC's Michael Cowan went through the figures posed by Furet. "He thinks that in five years they will reduce the cost of the construction of such houses by 25% while adhering to building regulations, and by 40% in 10 to 15 years."
Reasons why 3D printed house prices will go down are that the technology will undergo refinements, and one can expect economies of scale as more houses are built.
The 1,022 square feet house was built to curve around the 100-year-old protected trees on the plot, Cowan wrote. That points to a key advantage in using 3D printing for construction—far richer solutions in shape, and a creative experience opens up for architects to think outside the "box" of straight walls and cookie-cutter boxed rooms that one sees in traditional constructs.
The present-day limits are especially glaring in traditional public housing. Residents' units look more like confined prison cells blocking out the natural outdoors, minus only the bars on windows.
