Layer by layer, the brand new STRABAG BMTI (STRABAG Baumaschinentechnik Worldwide) warehouse in Stuttgart’s Weilimdorf district is rising upwards. Along with Putzmeister and its KARLOS cell concrete printer, ZÜBLIN has developed an revolutionary building methodology that’s distinctive on the planet. As a part of their long-standing collaboration, the 2 firms are pooling their revolutionary power to take 3D concrete printing to a brand new stage. Their analysis goals to supply prospects an much more versatile and sustainable printing course of sooner or later.
3D concrete printing to the subsequent stage
The brand new know-how relies on a truck-mounted concrete pump. An routinely managed increase with a attain of 26 meters applies concrete in a number of layers utilizing a particular stress head based mostly on a predefined digital building plan. On this means, storey-high, supporting concrete partitions are produced which can be room-sealing, i.e. stop the unfold of flames and smoke within the occasion of a fireplace.
The principle problem of 3D concrete printing to this point has been the shortage of scalability of the know-how for large-scale tasks. Till now, printing has primarily been carried out utilizing so-called gantry printers, that are restricted to the manufacturing of smaller buildings. In comparison with different concrete printing processes, KARLOS has better flexibility and vary as a cell building machine and due to this fact additionally gives the potential for scalability for large-scale tasks.
CO2-reduced concretes
The financial and ecological benefits of the tactic embrace the entire elimination of formwork, the manufacturing of strong wall cross-sections in a single operation and using CO2-reduced concrete. Through the use of solely inexperienced electrical energy for the all-electric machine and CO2-reduced concretes, ZÜBLIN and Putzmeister are making an essential contribution to creating constructing building extra sustainable in the long run.
“On our solution to realizing resource-saving and climate-neutral planning and building, ZÜBLIN developed a extremely revolutionary 3D printing course of along with Putzmeister. As a building group, we’re contributing our experience within the digital planning of constructing buildings and concrete know-how specifically to this pioneering innovation,” defined ZÜBLIN board member Stephan Keinath.
Putzmeister CEO Christoph Kaml sees KARLOS as a central factor of the corporate’s technique: “A excessive diploma of electrification and automation is required alongside all the work course of. The discount of handbook labor is a decisive think about coping with the rising scarcity of expert employees. As a digital know-how of the longer term, KARLOS is a central constructing block on the street to the development of tomorrow,” Kaml said.
3D printing as a driver of productiveness
Additive manufacturing strategies, specifically 3D printing, have grow to be an integral a part of industries akin to mechanical engineering, automotive and aerospace. Now they’re additionally more and more conquering building websites. The mix of manufacturing steps from the digital planning of the BIM mannequin (Constructing Data Modelling) by to the belief utilizing 3D printers is revolutionizing building processes. Work processes are considerably streamlined and accelerated by automation.
As ground-breaking because the know-how of 3D printing is, the human issue stays essential for the profitable realisation of building tasks. We’re due to this fact additionally countering the huge scarcity of expert labour with using fashionable applied sciences. This not solely will increase productiveness however above all additionally enthusiasm for an thrilling and promising building occupation with a brilliant future.
