The construction industry is rapidly adopting 3D printing. There are already enough examples of this: this is the creation of an entire village in Mexico, consisting of printed houses, and the construction of two-story houses in Germany using three-dimensional printing. The next step is already a three-story building.
The project was initiated by the German company Peri for the construction company Michael Rupp Bauunternehmung. The completed five-apartment three-storey building with a basement will have an area of about 400 sq. m. It is assumed that four apartments will be leased, and the fifth will house a showroom.
Dom will print COBOD’s BOD 2 printer. The machine will be modular with dimensions of 12.5 x 15 x 7.5 m. Its printing speed is 100 cm / sec, and it uses approximately 10 tons of concrete per hour. At the moment, this is the highest productivity among all construction 3D printers on the market.
The BOD 2 printing process itself is no different from other similar printers: the cement mixture is squeezed out through a nozzle, and then stacked in layers, forming a wall. BOD 2 is serviced by two operators, while other specialists continue to work inside the building under construction.
An important detail is that the walls are printed taking into account the engineering communications provided for by the project, which then makes it possible to lay pipes and electrical cables without problems.
The first floor has already been printed. The entire building will take about six weeks to complete.
