LOWER CONSTRUCTION cOSTS FOR LOWER RENTS

“With this apartment building, we are creating valuable living space and are continuing to work consistently on making construction more sustainable, both ecologically and economically,” explains Yannick Maciejewski, CEO of Rupp Gebäudedruck GmbH. “We are convinced that housing must be affordable for everyone. Construction using 3D building printing is an important and correct approach for this.” The unique KARLOS mobile 3D printer from Putzmeister is being used for the residential construction project in Vöhringen. The printing material used also plays a role: “We use ready-mixed concrete from SCHWENK from the nearest concrete plant. This means short transportation routes, lower travel costs and lower emissions.”

All of these factors will also have an impact on rental prices, as Fabian Rupp, developer and Managing Director of Michael Rupp Immobilien GmbH & Co. KG, explains: “As a landlord, we can naturally also charge lower rents with lower construction costs. All apartments are between 64 and almost 84 square meters in size, have their own cellar and balcony or terrace and are equipped with modern, high-quality furnishings.

PRACTICALITY AND SPEED:
THE KARLOS 3D PRINTER

The mobile 3D printer KARLOS was specially developed by Putzmeister and its spin-off KARLOS 3D for the construction industry in order to realize residential projects quickly, economically and in a resource-saving manner. The current construction of an apartment building in Vöhringen demonstrates the efficiency of this technology:

The mobile printer is ready for use in just one hour and has a reach of up to 26 meters, which enables fast and precise construction. Thanks to the short set-up time and high efficiency, the first floor and upper floor of the building were completed in just seven printing days. “Our technology is developed for real-life construction practice – the aim is to implement projects quickly and efficiently without compromising on quality and environmental friendliness,” says Markus Frasch, CEO of KARLOS 3D. “With KARLOS, we are driving the future of construction and making a contribution to sustainable, economical living space.”

Innovation against skills shortage

With the mobile 3D printer, projects can be realized despite the tight personnel situation on construction sites. Thanks to the efficient operation of KARLOS, only three people are needed for the printing process, which increases flexibility in scheduling, creates more attractive working conditions and counteracts the shortage of skilled workers in the construction industry. “Thanks to 3D printing, we can reduce the need for skilled workers and still work precisely and efficiently,” explains Rupp.

The best of two worlds combined

The concrete used for printing is a standardized building material. What makes it special is its special consistency and strength development. These properties are achieved through a precisely coordinated combination of cement and admixtures. The concrete is also characterized by a reduced CO2 footprint. The concrete is combined with modern insulation. It consists of prefabricated facing wall elements made of wooden frames with wood fiber insulation boards, which disappear behind plaster on the first floor and upper floor.
