Germany’s RoLaKI project uses AI and laser 3D printing to repair underwater steel structures efficiently and safely.
The German Laser Zentrum Hannover (LZH), the Institute of Information Processing (TNT) at the Leibniz University Hannover, and the research network OFTEC have launched the RoLaKI project, which deals with the development of the underwater metal 3D printing technology for the repair of critical infrastructure. The project aims to develop the laser-based additive manufacturing technology for the repair of offshore wind farms, bridge piers, and ports.
The primary objective of the project is to develop an AI-based 3D printing repair platform that can perform precise laser metal deposition processes on the submerged structures in the challenging environment. The researchers will also examine the effects of different parameters on the formation of layers and the quality of the repaired structure. This will be used to train the AI to suggest the best parameters for the repair task, thus developing the smart underwater 3D printing technology.
In addition to this, RoLaKI will develop special laser optics and a wire-feed laser cladding system installed on a magnetic crawler. This will enable precise movement and precise multi-pass welding, even in complex environments. The platform will utilize AI to develop the best route for repair, thus increasing speed and efficiency and ultimately increasing the lifespan of assets. The project is based on previous experiences at LZH in underwater lasers, including laser-guided ordnance neutralization and spectroscopy on underwater artifacts. By the end of this project, they aim to develop a prototype that will show a complete demonstration of underwater laser additive manufacturing solutions for various industries.
Considering the focus on automation, accuracy, and the inclusion of AI technology, RoLaKI has established Germany as the hub for industrial underwater additive manufacturing and metallic 3D repair solutions, which is seen as the way forward in the safe, quick, and cost-effective maintenance of underwater infrastructure. The business honor is of the view that the breakthrough in AI technology for underwater 3D printing by RoLaKI has the potential to redefine the repair and maintenance of the offshore and marine industries.
