3D Construction Printing

The first “BOD building” from the 3D construction printer

The idea for this project came about as a result of COBOD’s participation in a project financed by the Danish government called “3D Construction Printing”, which saw COBOD visit more than 35 3D construction printing projects around the world. It became apparent to COBOD that Europe was lagging behind and they took on the challenge of becoming the first company in Europe to 3D-print a building that could satisfy the stringent European building regulations.

Illustration of economic and architectural advantages of 3D printing 

The BOD, which is an abbreviation for “Building on Demand”, was given this name to draw attention to the fact that the 3D printing technology used in construction projects enables construction processes to be automated, thus pushing the boundaries of what is feasible. Even though the BOD is less than 538 sqft in size, it is still large enough to demonstrate some of the economic and architectural benefits of using 3D printing technology for buildings. When traditional building techniques are applied, any shape that is organic or curved in some way is a challenge, both from a technical and financial point of view.

The BOD does not have a single straight wall. The only straight elements are the windows and doors. Even in the case of the foundations, if anything other than straight lines are used in traditional processes, it becomes an expensive and complex challenge. It was for this reason that 3D printing was used not only for the walls of the BOD building, but also for a section of the foundations.

“We are glad that we took part in this project and made our contribution. We succeeded in coming up with a formula that is not only suitable for 3D printing, but also features a significant amount of recycled materials. Denmark is one of the frontrunners when it comes to recycling. With this project, however, we even managed to make the transition from the customary downcycling of rubble to recycling and upcycling.”

Repeated printing of the BOD building illustrates the potential of the technology

The creation of the BOD building - from planning to final realisation

The internal and external walls of the building were all printed at the same time.

Partially recycled materials were added to the concrete recipe, which is beneficial for the environment.

It is already possible to obtain construction permits for buildings using the 3D construction printer by integrating reinforcement and filling the hollow spaces.

After adding reinforcement and concrete to the cavities of the total of eleven printed column formworks that make up the building, the roof could be put on.

There are no straight walls in this house. Instead, curved and even undulating walls were built to reflect the location at the harbour.

Although only 50 m2 in size, the innovative house exemplifies the new construction method in a very impressive way.

Due to the individual shaping of the walls, the superbly finished internal area is a very special design highlight.
