Siemens 3D Printed Gas Turbine Blades

The collaboration between Siemens, Material Solutions and EOS demonstrates that 3D metal printing is a reliable and proven technology viable even for “moving” applications, without any compromise. In focus: developing a new turbine blade. The part was developed together with Siemens NX, built on EOS systems and produced by Material Solutions.

 

Outstanding Results

Performance:
Performance increased to 13,000 rpm

Heat stability:
Can be used with ambient temperatures of up to 1,250°C

Time savings:
75 % shorter development time
50 % quicker lead time

Turbomachinery is indispensable for energy generation. Its high-performance parts feature complex, high-tech designs that need to be more and more robust and powerful as the demand for energy increases. In addition, turbomachinery parts need to be resistant and reliable – even at temperatures beyond the melting point.

Additive manufacturing can solve many of these challenges and is suitable for numerous applications: blades and vanes, fuel injectors, impellers, swirlers, burners and combustion chambers, cladding, seals, housings, and much more. The 3D metal printing process (DMLS) offers the right technological foundations for implementing an optimized cooling strategy, among other things. Parts can be designed and made to transport and apply energy with increasingly precise focus. Innovative repair processes, for example, are revolutionizing the efficiency of turbomachinery parts by building at worn areas directly on the original part.

Improve parts and performance

Additive manufacturing allows you to manufacture complex parts with integrated functionality. Lower part costs and shorter lead times can also be achieved by reducing the rejection rate.

Accelerate research and development

Directly from CAD data: faster design optimizations and shorter development cycles become possible by building prototypes with 3D printing

Optimise repairs and maintenance

Reduced costs thanks to the ability to repair parts with complex cooling channels, less downtime.

Improve spare parts logistics

Spare parts on request: even small batch sizes can be manufactured cost-efficiency, reducing storage costs.

"If you can 3D print a turbine blade, you can print pretty much everything."
