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 cellular concrete printer, ZÜBLIN has developed an modern building technique that’s distinctive on this planet. As a part of their long-standing collaboration, the 2 firms are pooling their modern energy to take 3D concrete printing to a brand new stage. Their analysis goals to supply clients an much more versatile and sustainable printing course of sooner or later.
3D concrete printing to the subsequent stage
The brand new expertise 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 manner, storey-high, supporting concrete partitions are produced which might be room-sealing, i.e. forestall the unfold of flames and smoke within the occasion of a fireplace.
The primary problem of 3D concrete printing up to now has been the shortage of scalability of the expertise for large-scale initiatives. 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 higher flexibility and vary as a cellular building machine and subsequently additionally gives the potential for scalability for large-scale initiatives.
CO2-reduced concretes
The financial and ecological benefits of the strategy embody the whole elimination of formwork, the manufacturing of stable wall cross-sections in a single operation and the usage of 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 vital contribution to creating constructing building extra sustainable in the long run.
“On our strategy to realizing resource-saving and climate-neutral planning and building, ZÜBLIN developed a extremely modern 3D printing course of along with Putzmeister. As a building group, we’re contributing our experience within the digital planning of constructing constructions and concrete expertise 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 your complete work course of. The discount of guide labor is a decisive think about coping with the growing scarcity of expert employees. As a digital expertise of the long run, 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 comparable 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 means of to the conclusion utilizing 3D printers is revolutionizing building processes. Work processes are considerably streamlined and accelerated by means of automation.
As ground-breaking because the expertise of 3D printing is, the human issue stays essential for the profitable realisation of building initiatives. We’re subsequently additionally countering the large scarcity of expert labour with the usage of fashionable applied sciences. This not solely will increase productiveness however above all additionally enthusiasm for an thrilling and promising building occupation with a vibrant future.
