4MM60 - Advanced and additive manufacturing

Content

Additive manufacturing (AM) has disrupted the world of engineering manufacturing by offering a whole new set of technologies able to yield near net-shaped components, in reduced processing times and with minimized material wastes. 鈥淎dditive鈥� is in contrast with traditional subtractive manufacturing techniques: in AM, 3D components are produced starting from a CAD model by joining (melting or sintering) material together, typically in a layer-by-layer manner. Several technologies fall into the AM category, and they differ greatly in terms of working principles, processable materials, and scalability. Fabricating a component via AM is however not a single-step process, various preparatory and post-printing steps need to be planned and optimized. Additional challenges are the evolution of residual stresses and deformations due to phase transformations and evolving material microstructures, and the development of tools enabling the predictive modeling of a component evolution throughout the process. AM is also not a universal solution: material-specific limitations still stand, and therefore a knowledge of both alternative advanced processing routines and ongoing efforts in broadening AM鈥檚 applicability is of high importance.
This course then covers the following main topics:

  • Introduction to additive manufacturing 鈥� technologies evolution and overview, and associated materials science concepts.
  • AM technologies for polymers, metals and ceramics, with pre- and post-printing processing steps, including sintering and related technologies.
  • Modeling for AM 鈥� finite and discrete-element methods, multi-scale and thermomechanical modeling of AM processes.
  • Trends and perspectives in AM, with examples from recent research and case studies evaluations.
