Abstract

Additive Manufacturing enables the production of pump impellers with a much shorter lead-time than conventionally used casting processes. This is of particular importance for the maintenance and repair business, as it can lead to a reduction of down time or the necessity to keep spare impellers on stock.
Sulzer is developing an impeller manufacturing process which combines additive Laser Metal Deposition (LMD) with subtractive 5 Axis CNC Milling. The present paper describes the basic process steps, the advantages compared to commonly used manufacturing processes and the challenges to implement and to qualify this new manufacturing technology.
