Contour Crafter House Builder Concept by Sebastian Bertram offers a construction method that combines industrial production along with the technique of rapid prototyping. Contour Crafter is actually able to ‘print’ a two-storey family house. Since soon as the machine’s setup is complete, the design process runs automatically. Any robot prints contours of a building shell layer by layer using fast-drying concrete. Within a few weeks, a new whole housing estate could be produced.
