Numerical and experimental investigation of liquid crystal polymer 3D printing processes
High-performance lightweight parts can nowdays be manufactured using 3D printing techniques. In order to obtain complex parts with load-adapted microstructures, recent studies reveal the possibility and advantages of aligning thermotropic liquid crystal polymers (LCPs) during FDM printing. Thanks to the high degree of molecular alignment, the mechanical properties in the printing direction are 10x higher compared to top engineering materials for 3D printing such as PEEK.Nonetheless, the anisotropy resulting from the molecular alignment and the intrinsic nature of the 3D printing process leads to anisotropic final properties. Optimization of this intricate procedure is far from trivial as the current modeling approaches are limited and still in their early stage.

This project aims at optimizing the mechanical properties of 3D printed LCP parts in all dimensions by investigating the printing process. In addition to conducting experiments, numerical simulation tools will be employed to generate insights into the FDM process complexities and material behavior. For this purpose, we plan to utilize the “iMFREE” software, developed at the Advanced Manufacturing Laboratory and Institute of Machine Tools & Manufacturing, which is an efficient particle-based solver for modeling multiphysics problems.
Due to the multidisciplinary nature of this research, we look for highly motivated candaites with an analytical mindset who have studied Mechanical Engineering, Computational or Materials Science. Upon the completion of this project, two Master’s theses will be concluded: one mainly focused on the numerical modeling aspect of the project, and the other on the experimental and materials science issues.
