A 95 sqm 3D printed family home in France cost 20 per cent less to build than traditional building methods, at €195,000, according to Nantes University.
The 3D printer builds the walls by ‘printing’ a layer of polyurethane then a layer of cement then another layer of polyurethane, essentially the same build up as an insulating concrete formwork wall but with a robotic arm. The process just took a few days but then the roof, windows and services were added with traditional methods. batiprint3d.fr
