Towards additively manufactured dynamic rod seals
- In a recently started DFG-funded research project, the suitability of additive manufacturing methods and materials for the production of dynamic rod seals is investigated. Initially, a range of methods was defined, which shall be considered in the next phases of the project. For one of those methods, Fused Filament Fabrication (FFF), commercially available TPU-materials were analyzed. A set of potential materials has been defined and analyzed with respect to different criteria. These criteria comprise the processability, the static stiffness of the material, and the tribological properties. In a systematic process, the capability of the materials has been evaluated and compared with a commercially available reference sealing material to find the most promising ap- proaches. With these findings, a fully coupled FSI (fluid-structure interaction) simulation model was developed and parametrized to predict the behavior of 3D-printed seals under working conditions
