Number of the month for October: 2 construction workers

Only two construction workers are needed to build a house using a 3D printer. 3D-printed houses appear to be developing into a real trend. In this process, the house walls are printed using a concrete printer. This significantly reduces costs, material consumption, and construction time compared to conventional building methods. In early 2021, the first multi-family house and the largest 3D-printed house in Europe was completed in Wallenhausen in the district of Neu-Ulm.

The property is a five-unit apartment building with three floors and 380 square meters of living space. The printing process is estimated to take six weeks. The 3D printer is calibrated once and then prints concrete walls at a speed of up to one meter per second. Two construction workers are sufficient to operate the printer. In contrast, the conventional construction of a comparable property requires approximately 20 workers.

Our society would benefit not only from reduced construction costs, but also from a better environmental footprint thanks to material savings of up to 80 percent. Worldwide, more and more properties are being built using 3D printers, and they are becoming increasingly larger. As early as 2020, the largest house to date, measuring 640 square meters and spanning two floors, was printed in Dubai.
