Modelling internal cell structure for bioprinting processes — •Richard Kellnberger, Fabian Häusl, Moritz Lehmann, and Stephan Gekle — Universität Bayreuth, Bayreuth, Deutschland

The deformation cells experience during bioprinting processes depends on the structure of the cell and the stresses exerted by the surrounding fluid. We extended a Lattice-Boltzmann solver with a cell model using the immersed boundary method to model the cell membrane as well as discretizing the cell as elastic tetrahedrons in order to model the cytoskeleton. Furthermore, we extended the fluid model to take viscoelastic effects into account. With these extended models we improve our qualitative investigations of the deformation of cells during the printing process.
