RCAM Technologies is developing a basalt fiber reinforced concrete 3D printing technology for wind turbine towers.

What is the difference between these projects?
With an average tower height for land-based wind turbines installed in the United States at about 80 meters, RCAM Technologies wants to leverage 3D printing to erect them to the height of 140-170m. We say ‘to erect’ because additive technology is an instrument to manufacture concrete foundations that will maintain conventional steel sections.
When extremely high wind towers are under construction, their diameter is huge, so special-purpose vehicles and road conditions become very important. However, those towers could be manufactured onsite and concrete would be delivered to the 3D printer to bypass the logistics constraints.
The ultra-tall wind towers are expected to increase electricity production by more than 20 percent owing to stronger winds at this height, and present some cost savings in installation works, logistics and material cost.
The project of building towers and foundations for offshore wind turbines using additive technology doesn’t mean installing a 3D printer at sea. All construction work would be done at the port, or near the port at a pre-cast concrete plant. The parts would be designed in sections that could be cost-effectively transported over local roads or rail.

In nine months the startup will be able to address U.S. Department of Energy to receive the next $1 million grant. It will be considered within the same programme and based on the analysis of the first investment round results.
However, RCAM Technologies informs their project has generated interest and they are conducting negotiations about a possible partnership with several wind turbines manufacturers.
We have introduced our audience with a floating foundation project for deep offshore wind turbines where basalt plastic rebar used as a framework of a concrete buoy.
