Renishaw and Metalpine 3D Print Durable Parts for Harsh Maritime Environments

Renishaw, a company specializing in metal additive manufacturing systems, has entered into a strategic partnership with Metalpine, an Austrian producer of high-quality metal powders. The aim of this collaboration? To develop 3D printing solutions specifically adapted to the maritime sector. The companies are working together to design durable components that are capable of withstanding the extreme conditions of marine environments, where prolonged exposure to salt water accelerates corrosion and wear.

The project focuses on the use of copper-nickel alloys (CuNi) in powder form for 3D printing. These alloys are renowned for their anti-corrosion properties. Once treated by laser fusion, they form a protective layer that reinforces the resistance of parts in the aggressive marine environment. Two compositions were specifically studied: CuNi 10 (10% nickel, 90% copper) and CuNi 30 (30% nickel, 70% copper), each offering distinct characteristics in terms of laser behavior and mechanical performance.

3D Printing for the Creation of More Durable End-Use Parts

The components were manufactured using Renishaw’s RenAM 500Q Flex, a state-of-the-art metal 3D printer designed for research and development. Its ability to change powder rapidly, combined with the Reduced Build Volume (RBV) accessory, enabled trials to be carried out with just 0.25 liters of powder, while simulating large-scale production conditions. This approach was decisive in optimizing printing parameters while minimizing material waste.
