COBOD ‘imprimirá’ casa en Alemania

Henrik Lund-Nielsen, founder and CEO of COBOD explained that "we are very pleased that we are starting to see the fruits of the many 3D building printers we have sold since the launch of the BOD 3 2D building printer in 2019. The projects have been delayed by the coronavirus, but now they are beginning to be revealed. These buildings and the great interest in them document that our technology, and the buildings they can make, are ready for the market."

Thomas Imbacher, Head of Innovation and Marketing at PERI GmbH, said: "We are very confident that 3D building printing will become increasingly important in certain market segments over the coming years and has considerable potential. We are proud that PERI's involvement in the Beckum project has made us pioneers and forerunners of this new construction technique."

Technology

PERI is constructing the building in Beckum with the help of COBOD's BOD2 printer. The BOD 2 has a modular construction and can be extended in any direction with modules from 2.5 meters, up to a maximum of 15 meters wide and 10 meters high. In length, the printer can be as long as desired. For the Beckum building, PERI is using a BOD 2 of 12.5 m * 15 m * 7.5 m. The BOD 2 printer has a maximum speed of 100 cm/sec, equivalent to printing/emptying 10 tons of concrete per hour. The printing material was provided by Heidelberg cement.

The BOD 2 has also been used to make large concrete structures, such as the world's first 3-meter 10D printed windmill tower, which COBOD made under a long-term cooperation with GE.

"The BOD 2 is a very versatile printer. At Beckum, PERI has chosen to use a long printer, while we used a much shorter but taller printer to print the 10m tower for GE. This was the fundamental idea behind the modular design of the printer: it is always possible to find a size that meets the customer's needs," said Michael Holm, director of R+D at COBOD.
