Wärtsilä Optimizes Industrial Impeller for Additive Manufacturing


The Desing 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.
