Germany will build a residential complex using 3D printing and low-carbon cement

In Heidelberg, Germany, construction begins on the Dreihaus residential complex, which will be a testbed for low-carbon building technologies. A key feature of the project is the use of 3D printing and innovative cement mixes.

The project comprises 3 three storey buildings, each demonstrating a different approach to reducing CO₂ emissions:

- Two of the buildings will use evoBuild compound. According to the developer, this mix reduces carbon dioxide emissions by 30 per cent compared to traditional concrete. In absolute terms, the savings amount to almost 552 kg CO₂ per tonne of cement material. In addition to low emissions, the mix has a high density and is recyclable.

- A third building is planned to be constructed using evoZero material. This is the world's first cement mix positioned as a zero net carbon emission product. The technology is based on the complete capture of CO₂ emissions directly at the production plant.

The project is being realised by Heidelberg Materials, one of the world's leading manufacturers of building materials. The aim is to test and commercialise technologies that can reduce the carbon footprint of the construction industry, which is estimated to account for up to 40% of global CO₂ emissions.

The use of 3D printing in this case is not only aimed at demonstrating technological capabilities, but also at accurately dispensing materials, which reduces waste on the construction site.
