Sandra Lucas is an assistant professor in 3D printing of concrete in the research group Concrete Structures at the TU/e department of the Built Environment (unit Structural Design). Sandra’s research goal is to understand how material’s modification can alter its microstructure, how this influences the macromechanical behaviour, creating new properties – self-healing, self-sensing, heat storage or self-cleaning, for example. At TU/e, her research focuses on transferring this knowledge to additive manufacturing, developing fully customisable 3D printed materials and buildings. She is the project leader of two consortium projects supported by NWO (the Dutch research council) – ‘Additive manufacturing of functional construction materials on-demand’ and ‘Additive manufacturing of sustainable concrete for zero-energy buildings’.
