The 3D-printed building is expected to be completed by July and will house computer servers.
Construction is underway for what is being billed as “Europe’s largest 3D-printed building in the southern German city of Heidelberg.
Once completed, it will be 55 metres long, 11 metres wide and 9 metres high and will house a data centre.
The construction work normally carried out by dozens of human workers is done by a gigantic robot that prints layers and layers of concrete on top of each other. The entire process is expected to take just 140 working hours.
“It’s very innovative. At a later stage it’s imaginable that there is just one person at the construction site to make sure nothing goes wrong,” said the developer, Hans-Joerg Kraus.
His company, the Kraus Gruppe, says the concrete used is made of 100 per cent recycled materials and will reduce the emission of CO2 by 55 per cent compared to pure Portland cement, the type of cement most commonly used around the world.
