From the 3D printer to patent pending: Guide vane segment for a MAN Diesel & Turbo gas turbine

MAN Diesel & Turbo: 3D printing becomes a standard

As of now, MAN Diesel & Turbo is equipping gas turbines with 3D-printed components.

Dr Roland Herzog, Head of Material Technology in the Strategic Business Unit Turbomachinery: “Additive manufacturing offers huge potential for our product range, especially when it comes to the production of gas turbine components. Additively manufactured guide vane segments that we are now incorporating into our type MGT6100 gas turbines have proven particularly suitable. The approval for serial production is the result of intense cooperation with highly specialized suppliers and development partners such as the Fraunhofer Institute for Laser Technology.”

In order to exploit the potential of the technology even further, MAN Diesel & Turbo is currently investing in the “MAN Center for Additive Manufacturing”, a product and location-independent expert centre based at the company’s turbomachinery works in Oberhausen. Design specialists, materials experts and production engineers come together at “MANCAM” to extend the benefits of additive manufacturing to further components and products, for example compressor impellers or fuel nozzles for engines.

Herzog: “As well as shortened development cycles, 3D printing gives more freedom for innovative, superior component designs, reduces production and delivery times and enables us service-wise to produce spare parts on call.”

Additive manufacturing, also known as 3D printing, covers a range of innovative production processes, the potential of which is currently being investigated and developed in various industries, including machine and vehicle manufacturing, the aerospace industry and medical technology. As well as plastic materials, there are now also processes, which enable 3D printing based on metallic materials. Examples include Selective Laser Melting (SLM) and Electron Beam Melting (EBM). Depending on factors such as lot sizes and material costs, these open up benefits over conventional production processes along the whole value chain of a product – from development and production through to maintenance and service.
