Plan, enter data and press the printer button – the dream house is ready. In Beckum, the first single-family house is inaugurated straight from the printer.
In Beckum, Westphalia, the first house in Germany from the 3D printer, according to the state, was officially opened.
At the meeting, NRW building minister Ina Scharrenbach (CDU) praised the “far-reaching role model function” of the pilot project. The new construction method promises time savings and a “leaner construction process”. Given the shortage of skilled workers in the industry, this is a decisive advantage. In addition, previously particularly complex shapes such as curves could be implemented more easily.
The two-story single-family house has around 160 square meters of living space. During construction, the 3D printer uses a nozzle to apply special mortar and concrete, digitally controlled, in layers that are centimeter thick. The printer can be used flexibly and is faster because it no longer has to be put stone on stone. He can do one square meter in five minutes, according to the ministry.
NRW approved the project after individual assessments and funded it with almost 200,000 euros. “Now it is important to gain experience with the building and to establish the manufacturing process on the market, because only more living space ensures affordable rents,” said Scharrenbach. The state ministry hopes to gain experience from the project that will be exemplary for the entire construction industry. In several other countries, such as the USA or Belgium, there are already buildings from the printer.
According to the Bauen-Agrar-Umwelt industrial union, “every move that leads to significantly faster construction” is to be welcomed in principle. There is a big deficit, especially when it comes to affordable housing and social housing, where the 3D printer can be helpful. However, it would have to be guaranteed that the resulting buildings are also produced in the digital process with high quality and sustainably. Particularly in construction, with its structure characterized by small and very small companies, it must be ensured that the employees are involved in the necessary qualification processes.
