  text: The Fused Filament Fabrication (FFF) process is increasingly used for the
    manufacturing of individualized and complex structures, which continuously results
    in new requirements regarding the material properties. A characteristic material
    property for polymers is the low thermal conductivity. However, for specific applications,
    such as additively manufactured injection molding tool inserts, increased thermal
    conductivity is advantageous. In this study, the influence of fillers of different
    types, shapes and sizes on the resulting thermal conductivity of compounds is
    investigated. The aim is to analyze the effects of the fillers, considering the
    FFF-typical strand structure. The first step is to characterize the fillers in
    terms of shape and size. Based on this, the resulting thermal conductivity of
    specimens manufactured in the FFF process for different build orientations is
    specifically examined and compared to injection molding. This ensures that the
    process- and material-related anisotropy of the specimens is considered in the
    analysis. For the evaluation, a methodology is developed to be applied in Laser
    Flash Analysis (LFA), which allows the results to be evaluated despite the characteristic
    FFF surface structure. For the final visualization of the influence of the particle
    size on the particle orientation, Scanning Electron Microscopy (SEM) images of
    the relevant polymer compounds are made. The investigations provide a data basis
    regarding the influence of the particle type, shape and size on the thermal conductivity
    as well as for the requirement-oriented selection of fillers for processing thermally
    conductive polymer compounds in the FFF process.
