Dr.-Ing. Sebastian Piegert & Dr. Cynthia Wirth

Additive Manufacturing (AM) is revolutionizing the energy sector by enabling OEM's to accelerate the energy transition. Siemens Energy is at the forefront of this transformation, leveraging AM to enhance the efficiency and performance of energy systems as well as improving the maintenance and repair of traditional infrastructure. In this talk, we will explore Siemens Energy’s global AM footprint, addressing the challenges and strategic vision in three critical areas: material cross-site qualification, machine fleet consistency and the contribution of the digital thread to quality assurance in serial production.

By adopting AM, Siemens Energy is not only driving down product costs and mitigating internal supply chain issues but also contributing to a more sustainable and resilient energy landscape. 

Sebastian Piegert is leading the global Additive Manufacturing Technology Development function within the Additive Manufacturing organization of Siemens Energy Gas Services out of the gas turbine plant in Berlin since 2022. In a similar function he was leading the Additive Manufacturing Technology and

Materials team for Siemens Energy Generation Large Rotating Equipment since 2014. He started his career within Siemens as development engineer for joining and repair processes for hot gas path 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“.  

Dr. Cynthia Wirth leads the Digitalization and Innovation Team for Additive Manufacturing at Siemens Energy since October 2022. She joined Siemens Energy in 2015 and has worked since then in different roles. She holds a diploma engineering degree (2003) in Materials Science and Engineering from the Federal University of Paraiba, Brazil. She received a master’s degree and PhD also in Material Science and Engineering at the Federal University of Santa Catarina in 2005 and 2008, respectively. During her PhD, she spent one year as DAAD scholarship holder at the Friedrich Alexander Universität Erlangen-Nürnberg, in Erlangen, Germany. She has been working since then with Additive Manufacturing, focusing on different applications. After her PhD, she joined the Additive Manufacturing group for Ceramic Processing at the FAU Erlangen-Nürnberg for her postdoctoral, working with FDM of metal-filled filaments, robocasting of ceramics, Laminated Object Manufacturing of ceramic tapes. In 2011, she joined the Federal Institute for Materials Research and Testing, BAM, in Berlin, where she supported building the group of binder jetting of bio-resorbable ceramic implants.
