Sebastian Piegert is leading the Additive Manufacturing Technology and Materials Development function within the Additive Manufacturing organization of Siemens Energy Generation out of the gas turbine plant in Berlin since 2014. He is also acting as the technology field lead for additive manufacturing for entire Siemens Energy. He started his career within Siemens as development engineer for joining and repair processes for hot gas paths components of large gas turbines in 2008. Mr Piegert studied mechanical engineering at the technical university of Braunschweig (Germany). In order to deepen his expertise in high temperature materials and their applications, he subsequently conducted a doctorate at the Institute of Materials of the Technical University Braunschweig exploring „Modern high temperature brazing processes for turbine blade and vane repair“.

An international expert in metallic materials for power plants, Steve specializes in additive manufacturing (3D printing). He works with operators, assisting in materials assessment as part of root cause analysis, as well as remaining life assessment and creep damage evaluation. He also has extensive experience in quality assurance and technical audits associated with strategic spare part manufacture. Steve currently manages multidisciplinary projects focusing on the full range of materials used in the energy sector, such as integrating new manufacturing processes, including 3D printing, in industrial environments.

John Oakey is board member at ETN Global. He also works as a Professor of Energy Technology, at Cranfield University (UK). As AM is increasingly used across several industries including the energy industry, the gas turbine technology community quickly becomes aware of its potential. As ETN aims to provide key insights and valuable information that will help its community move forward, ETN has divided its work and collaboration with its companies members into 5 key areas of interest: Air Filtration, Exhaust Systems, Hydrogen, Micro Gas Turbine and obviously Additive Manufacturing. It goes without saying that at some point, all groups can benefit from the expertise brought by others. As the board member of ETN Global and a professor of Energy Technology, Oakey is uniquely positioned to bring key insights into the ins-and-outs of the energy industry and why AM can be an interesting production candidate for energy companies.
