Project duration: 1 January 2019 – 31 December 2021


The aim of this project is to address the need for more efficient and waste-free production, specifically the production of corrosion-resistant components operating in marine environments.

The solution (technology)

Using newly developed Cu-based alloys in applications such as water turbine propellers, ship propellers, valves, manifolds and other marine equipment, by means of Wire+Arc Additive Manufacturing (WAAM) or more precisely the 3D Metal Printing (3DMP®) technology, a significant reduction of costs and energy consumption can be reached.
The principle of the 3DMP® technology is to make the final product layer-by-layer using a metal filler wire as input material. This approach is more efficient than manufacturing by means of typical 3D printers which use metal powders due to the lack of input material losses.
