FAU MoD Lecture: From Process Physics to Predictive Manufacturing: Challenges in Modelling Electron Beam Powder Bed Fusion
Speaker: Dr.-Ing. Matthias Markl
Affiliation: Numerical Simulation Group at the Chair of Materials Science and Engineering for Metals at Friedrich-Alexander-Universität Erlangen-Nürnberg (Germany)
Abstract. Electron Beam Powder Bed Fusion (PBF-EB) is a complex additive manufacturing process involving multiple interacting physical phenomena across a wide range of spatial and temporal scales. Understanding the relationships between process parameters, material behaviour and the resulting material properties remains a major challenge, requiring a combination of experimental investigation and physics-based numerical modelling.
This lecture presents the challenges of modelling PBF-EB across different scales, highlighting the capabilities of current simulation approaches as well as their computational demands and limitations. The increasing complexity of the process and the large parameter spaces involved raise fundamental questions about how simulation-based knowledge can be used more efficiently to understand, predict and ultimately design manufacturing processes.
Against this background, the lecture explores potential connections between physics-based modelling, data-driven approaches and mathematical optimisation. Rather than focusing on a particular machine learning method, it discusses the opportunities and open questions involved in combining these approaches, from accelerating computationally expensive simulations to moving towards inverse process design. The aim is to illustrate a challenging application domain in which manufacturing science, computational modelling, applied mathematics and artificial intelligence can complement one another.
OUR SPEAKER
Dr.-Ing. Matthias Markl is the Head of the Numerical Simulation Group at the Chair of Materials Science and Engineering for Metals at Friedrich-Alexander-Universität Erlangen-Nürnberg, Germany. Since 2020, he has also served as Managing Director of the Collaborative Research Center Transregio 103 Superalloy Single Crystals. His research focuses on the numerical simulation of metal additive manufacturing, particularly electron beam powder bed fusion, covering process physics, microstructure evolution, and process optimization. He has authored more than 60 peer-reviewed journal publications and has contributed extensively to the development of simulation methods for powder bed fusion. Dr. Markl is actively involved in organizing international conferences on additive manufacturing and serves as guest editor for several special issues in the field.
