The Unprecedented Capabilities of the COBOD 3D Printer

At the heart of GE Renewable Energy’s Bergen research facility lies a concrete 3D printer that is truly in a class of its own. This particular unit, developed by COBOD, is not merely an off-the-shelf solution; it has been custom-engineered and precisely tailored to meet the exacting and ambitious demands of the American energy giant. Its unique design allows it to achieve unprecedented printing heights of up to 20 meters, making it possible to construct significantly taller bases for wind turbine towers than previously feasible with conventional methods. This capability is a game-changer for the wind energy industry, as taller towers can access stronger and more consistent wind resources at higher altitudes, directly translating into increased energy capture and greater overall efficiency of wind farms.

The ability to print these massive structures on-site mitigates many of the logistical nightmares and environmental concerns associated with transporting enormous prefabricated tower sections. Traditional methods often require complex and costly heavy-haul logistics, specialized permits, and extensive infrastructure modifications to move components from factories to remote wind farm locations. By contrast, on-site 3D printing reduces the need for such intricate transportation, lowering costs, minimizing traffic disruption, and significantly decreasing the carbon emissions linked to logistics. Furthermore, the inherent flexibility of additive manufacturing allows for optimized structural designs that can be tailored to specific site conditions and wind profiles, leading to more robust and efficient turbine installations. This bespoke approach to construction, powered by COBOD’s advanced printing technology, positions GE Renewable Energy at the forefront of innovation in the global renewable energy landscape.

He remarked, “We are extremely proud to have delivered a completely new type of 3D concrete printer — the largest of its kind in the world — for this world class and state of the art facility. The printer we have delivered is second to none: not only can it print in excess of 10 tons of real concrete per hour, but in addition, it is the first 3D concrete printer in the world with two X-axes on the printer. With the multiple functions of the printer, the printer can better be described as a multifunctional construction robot than a printer.” Lund-Nielsen’s statement vividly paints a picture of a machine that transcends the traditional definition of a printer, evolving into a sophisticated construction robot capable of complex, high-volume work.

The printer’s ability to extrude over 10 tons of concrete per hour highlights its industrial-scale capacity and efficiency, far surpassing the capabilities of smaller, more conventional 3D printers. This speed is crucial for meeting the demanding construction schedules of large-scale wind farm projects. The innovative inclusion of two X-axes is another game-changer, providing unparalleled flexibility and precision in the construction process. This dual-axis system allows for more complex geometries, faster build times, and potentially the integration of additional functionalities directly into the printing process, such as rebar insertion or sensor integration. This technological leap enables the creation of highly optimized tower bases that are not only structurally sound but also engineered for maximum performance and longevity in challenging environmental conditions.
