Additive manufacturing

Additive manufacturing processes offer great potential with regard to geometrically complicated structures to be manufactured. We are researching new methods for modelling and design of such manufacturing processes. In particular, we are working on Laser Powder Bed Fusion (LPBF) and Fused Filament Fabrication (FFF). Special attention is focused on the observation of the process on different scale levels in order to predict the locally different as well as complex structural properties due to the underlying material properties as well as process control. Furthermore, we deal with the modeling of locally occurring interfaces.

Research focus
  • Simulation of the printing process and prediction of the resulting temperature history at component level
  • Warpage simulation based on the determined temperature history on component level
  • Modeling of the FFF at the meso level for virtual characterization of the local properties of the printed structure
  • Process hybridization
  • Interfacial modeling
