The Design Brief by nTopology describes how Wärtsilä’s engineers redesigned the centrifugal pump impeller for additive manufacturing. Not only was the optimized turbomachinery component 44% lighter, but it was generated using an automated design process, enabling customization.
The selected turbomachinery component was a closed centrifugal pump impeller originally manufactured with metal casting. Its outer diameter was 200 mm, and the weight of the original part was approximately 2 kg.
Transitioning from a traditional process to additive manufacturing brings multiple advantages to Wärtsilä that are related to the impeller’s performance and the factory management and operations.
