The ARC Training Centre for Multiscale 3D Imaging, Modelling and Manufacturing’ is known under the name (the ARC Training Centre for) M3D Innovation. Its aim is to foster close partnerships between university-based researchers and research end-users and to provide innovative Higher Degree by Research and Early Career Research training. M3D Innovation is funded by the Australian Government under the Australian Research Council Industrial Transformation Training Centers (ARC ITTC) scheme to train a new generation PhD students and Postdocs in the emerging area of Digital Materials. The projects are run in collaboration with our industry partners and promise to deliver step changing results within diverse fields, from natural resources to medical devices and heritage studies. The core principle of all M3D Innovation projects is to garner a deep understanding of the structure of materials at multiple scales. By using cutting edge micro-CT imaging, reconstruction, analysis and visualisation methods developed at ANU over the last 15 years, researchers can probe, analyse, model and reconstruct the 3D structure of material samples at the metre scale with resolutions down to a few hundred nanometres.
