PERI GmbH has set about printing another residential building using a 3D construction printer, this time in Wallenhausen, Bavaria. At the end of September 2020, the family-owned company announced that work had begun on Germany’s first printed residential house in Beckum, North Rhine-Westphalia. Only two months later, work has begun on the next residential building to make use of 3D construction printing technology. Upon completion, the 5-in-a-block apartment building with around 380 square metres of living space will be the largest printed residential building in Europe. On this project, the printing process is expected to take six weeks.

The client on this apartment building project is Michael Rupp Bauunternehmung GmbH, which will specialise in the 3D sector from 2021 onwards through its newly founded subsidiary Rupp Gebaudedruck.

The planning architect is the architectural firm Muhlich, Fink & Partner BDA from Ulm. The materials used to produce the printable concrete are being sourced from HeidelbergCement. The mixing technology used has been sourced from m-tec mathis technik gmbh. The engineering office Schießl Gehlen Sodeikat assisted with the preparation work for the warrant. The Technical University of Munich planned and carried out the relevant approval tests.

The residential building in Wallenhausen has a full-length basement and, upon completion, will consist of five apartments across three floors with around 380 square metres of living space. This is not a research or demonstration project. Once construction is complete, the apartments will be rented out in the usual manner. Only one of the apartments will be used as a show apartment.

PERI is using the gantry printer BOD2 for this construction printing project in Wallenhausen. The system has a print head that moves about 3 axes on a securely installed metallic frame. The benefit here is that the printer can move along its frame to any position within the construction and only needs to be calibrated once. This saves time and cuts costs.

During the printing process, the printer takes into account the pipes and connections for water, electricity, etc. that are to be laid at a later time. The BOD2 has been certified in such a way that it is possible to carry out work within the printing area while printing is in progress. This means that manual work, such as the installation of empty pipes and connections, can be easily integrated into the printing process.
