Multi-scale and multi-physics numerical simulation in Powder-based Metallic Additive Manufacturing

Powder bed based additive manufacturing technologies such as Laser Powder Bed Fusion (L-PBF) or Selective Electron Beam Melting (SEBM) have been revolutionizing the manufacturing industry for the past decade with their ability to produce functional metallic components with highly complex geometry without the need for additional tooling. The outputs of this thesis assist significantly to the understanding of the process, hence, contributing to the optimization and customization of the process as well. In addition, obtained results in this work may pave a way to 3-D print light-weight materials such as magnesium whose print-ability remains the biggest challenge.
