A 1:25-scale gas turbine that demonstrates the potential and limitations of powder bed-based additive manufacturing (AM)technologies has been created in a collaboration between the H+E-Produktentwicklung GmbH in Moritzburg, Saxony, the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden. The technology demonstrator is a model of a Siemens SGT6-8000 H gas turbine for power generation and was completely manufactured with additive processes, except for the shaft. The assembly comprises 68 parts made of aluminium, steel and titanium, which through component optimisation and the possibilities of electron and laser beam melting technologies replace the almost 3,000 individual parts that make up the original component. Some parts were also machined subsequent to AM creation. The turbine is fully functional.
