CSIRO to hold ‘Digital Twin’ symposium for metal Additive Manufacturing in Melbourne

The Commonwealth Scientific and Industrial Research Organisation (CSIRO) will hold a one-day symposium titled ‘Towards a True Digital Twin’, in Melbourne, Australia, on July 4, 2019. The symposium will bring together experts in a range of relevant fields including metal Additive Manufacturing, computational modelling, multi-scale techniques, structure-property relations, machine learning and artificial intelligence, and digital twins of industrial processes.

CSIRO states that for AM to reach its full potential, a realistic virtual representation of the complete process is required. A ‘digital twin’ will accelerate process design and optimisation, and form a key part of process certification and component qualification, but the development of a digital twin reportedly presents huge challenges. The organisation reports that not only do accurate and fast computational sub-models of the complex physical and metallurgical processes involved (powder-bed raking, heat transfer and flow in the molten pool, microstructure formation, residual stress development) have to be produced and validated, but they have to be tightly integrated.

This is a critical obstacle, since the sub-models use different computational approaches and treat vastly different scales, from powder (~50 µm) to part (up to metres). Through keynote lectures, poster presentations and facilitated discussion sessions, the symposium aims to:

  • Define the requirements for a true digital twin of the Additive Manufacturing process
  • Identify the main barriers to developing such software, including those involved in linking sub-models across scales
  • Explore the physical, metallurgical and computational approaches to overcome these barriers
  • Set out a roadmap for the development of a digital twin


The digital twin symposium will follow APICAM 2019 (2nd Asia-Pacific International Conference on Additive Manufacturing), to be held in Melbourne, Australia, from June 31 to July 3.

Keynote speakers will include:

  • Tarasankar DebRoy, Pennsylvania State University, USA
  • Dongdong Gu, Nanjing University of Aeronautics and Astronautics, China
  • Leila Ladani, University of Texas at Arlington, USA
  • Ibo Matthews, Lawrence Livermore National Laboratory, USA
  • Chris Vains, Siemens Australia
