  text: "Polymer composites represent the industry standard in injection molding for
    the production \r\nof plastic components with increased requirements in terms
    of heat resistance and stiffness. In the \r\nfield of laser sintering (LS), these
    materials are less common so far. In order to extend the available \r\nmaterial
    variety for the LS process, new ceramic-filled Polyamide 613 powders are investigated\r\nwithin
    the scope of this work. Here, the resulting properties from two different powder
    production \r\nmethods are compared. One filled powder is produced by dry blending
    and the other powder with \r\nthe same filler and filling ratio is produced by
    encapsulating the filler particles inside the polymer \r\nparticles within the
    dissolution-precipitation process. It was found that encapsulating the filler
    \r\nparticles can provide certain benefits for the processability, for example
    an improved powder \r\nflowability or better filler dispersion. However, encapsulating
    the filler also alters the thermal \r\nproperties of the precipitated powder."

  text: "Iron oxide nanoparticles are very interesting for many applications in different
    industrial sectors. A promising\r\nprocess to manufacture these nanoparticles
    is flame spray pyrolysis (FSP). A lack of understanding of the\r\nindividual sub-processes
    in FSP makes it challenging to tailor nanoparticle properties. This work provides\r\ninsights
    into the formation of iron oxide nanoparticles in a turbulent spray flame using
    Large Eddy Simulations\r\n(LES), which are based on a comprehensive model, including
    customized submodels. Highlights are the\r\nadaption of a turbulent combustion
    model and a bivariate hybrid method of moments for modeling nanoparticle\r\ndynamics.
    The work focuses on the SpraySyn burner, which is a standardized laboratory burner
    and was\r\noperated with a precursor-solvent mixture of ethanol and iron(III)
    nitrate nonahydrate. For studying the\r\nrelevance of precursor chemistry, LES
    using an evaporation-limited precursor chemistry model is compared\r\nwith a model
    that includes detailed iron chemistry. A further novelty is the inclusion of adsorption
    in the\r\nsimulation, which defines a third model for comparison. Sufficient validation
    is achieved for the undoped LES\r\nusing experimental data from the literature.
    A strong impact of the detailed iron chemistry and adsorption\r\nis found on the
    precursor consumption and the aggregate and primary particle formation. Comparing
    the\r\nparticle diameters with experimental measurements from the literature and
    data generated for this work is\r\nfound unsuitable to asses the precursor chemistry
    model and revealed an urgent need for future experimental\r\nand numerical research.
    This work serves as a step forward in realizing a reliable model."

  text: 'Polymer composites represent the industry standard in injection molding for
    the production of plastic components with increased requirements in terms of heat
    resistance and stiffness. In the field of laser sintering (LS), these materials
    are less common so far. In order to extend the available material variety for
    the LS process, new ceramic-filled Polyamide 613 powders are investigated within
    the scope of this work. Here, the resulting properties from two different powder
    production methods are compared. One filled powder is produced by dry blending
    and the other powder with the same filler and filling ratio is produced by encapsulating
    the filler particles inside the polymer particles within the dissolution-precipitation
    process. It was found that encapsulating the filler particles can provide certain
    benefits for the processability, for example an improved powder flowability or
    better filler dispersion. However, encapsulating the filler also alters the thermal
    properties of the precipitated powder. '

  text: The high flammability of components manufactured by laser sintering (LS) using
    standard polyamide 12 (PA12) powder still severely restricts their use in industries
    such as electronics, aviation, and transportation. A key factor for the further
    establishment of LS is the expansion of the material portfolio with, for example,
    refreshable and halogen-free flame-retardant (FR) powder materials. Accordingly,
    various halogen-free FRs are investigated in this work and evaluated with respect
    to their use in LS. First, their decomposition behavior and mode of action are
    examined. Subsequently, the additives are dry blended with PA12 to investigate
    properties relevant for LS, such as particle morphology, thermal behavior and
    melt viscosity. Afterwards, test specimens for UL94 vertical flame-retardancy
    tests are produced by processing the dry blends on an EOS P3 LS system. Finally,
    the process stability of the process-aged powder blends is investigated by again
    examining the thermal behavior and melt viscosity.

  text: "<jats:title>Abstract</jats:title><jats:p>The use of structured measuring
    systems to prevent wall slip is a common approach to obtain absolute rheological
    values. Typically, only the minimum distance between the measuring surfaces is
    used for further calculation, implying that no flow occurs between the structural
    elements. But this assumption is misleading, and a gap correction is necessary.
    To determine the radius correction <jats:inline-formula><jats:alternatives><jats:tex-math>$$\\Delta

    for specific geometries, we conducted investigations on three Newtonian fluids
    (two silicon oils and one suspension considered to be Newtonian in the relevant
    shear rate range). The results show that <jats:inline-formula><jats:alternatives><jats:tex-math>$$\\Delta

    is not only shear- and material-independent, but geometry-dependent, providing
    a Newtonian flow behaviour in a similar viscosity range. Therefore, a correction
    value can be determined with only minute deviations in different Newtonian fluids.
    As the conducted laboratory measurements are very time-consuming and expensive,
    a CFD-approach with only very small deviations was additionally developed and
    compared for validation purposes. Therefore, simulation is an effective and resource-efficient
    alternative to the presented laboratory measurements to determine <jats:inline-formula><jats:alternatives><jats:tex-math>$$\\Delta

  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>The accessibility
    to rheological parameters for concrete is becoming more and more relevant. This
    is mainly related to the constantly emerging challenges, such as not only the
    development of high-strength concretes is progressing very fast but also the simulation
    of the flow behaviour is of high importance. The main problem, however, is that
    the rheological characterisation of fresh concrete is not possible via commercial
    rheometers. The so-called concrete rheometers provide valuable relative values
    for comparing different concretes, but they cannot measure absolute values. Therefore,
    we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement
    of fresh concrete with particles up to <jats:inline-formula>\r\n                     <jats:alternatives>\r\n

    \                 </jats:inline-formula>. The comparison of the ACCR with a commercial
    rheometer showed very good agreement for selected test materials (Newtonian fluid,
    shear thinning fluid, suspension, and yield stress fluid), so that self-compacting
    concrete was subsequently measured. Since these measurements showed a very high
    reproducibility, the rheological properties of the fresh concrete could be determined
    with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified
    Bingham (MB) models) were also tested for their applicability, with the Bingham
    and the modified Bingham model proving to be the best suitable ones.</jats:p>"

  text: In this work, the influence of the filler–matrix adhesion on the tensile properties
    of laser-sintered parts built with Polyamide 613 filled with glass beads was investigated.
    For this purpose, dry blends of glass beads with and without organosilane coupling
    agents and polyamide powder were prepared and processed into tensile specimens
    on an EOS P396 laser sintering system. The samples were tested both in the dry
    state and after an accelerated conditioning in a climate chamber. Furthermore,
    finite element method (FEM) simulations were performed to model the extreme cases
    of optimum adhesion and no adhesion. By correlating the tensile tests with the
    simulation results and by analyzing the fracture surfaces, it was shown that the
    filler–matrix adhesion is sufficient in the dry state but is strongly degraded
    by conditioning. Even the presence of various organosilane thin films could not
    prevent a strong deterioration of the filler–matrix adhesion and the associated
    deterioration of the mechanical properties. Since a comparison with an injection-molded
    sample of the same polymer filler combination shows identical behavior after conditioning,
    it is assumed that this problem is not limited to additively manufactured parts.

  text: In the laser sintering technology, the semi-crystalline polymer material is
    exposed to elevated temperatures during processing, which leads to serious material
    ageing for most materials. This has already been investigated intensively by various
    authors. However, the ageing of the material at ambient temperatures during shelf
    life has not been the focus so far. The need to analyse the shelf life can be
    derived from an ecological and economic point of view. This work is focusing on
    the shelf life of PA2200 (PA12). To reduce the potential influences of powder
    production fluctuations, two different powder batches stored for 5.5 years and
    6.5 years are investigated and compared to a reference powder produced 0.5 years
    before these investigations. Multiple powder analyses and part characterisations
    have been performed. A significant yellowing and molecular chain length reduction
    can be derived from the measurement results. Whereas the influence on mechanical
    part performance was minor, the parts built with the stored powders are more yellowish.
    As it is most likely that this is due to the consumption of polyamide stabilisers,
    it can be assumed that these parts will be subject to significantly faster ageing.
    Therefore, it is still not recommended to use the stored powders for critical
    parts or light intense and humid environments.
