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.

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."}],"editor":[{"last_name":"Fröde","full_name":"Fröde, Fabian ","first_name":"Fabian "},{"last_name":"Grenga","full_name":"Grenga, Temistocle ","first_name":"Temistocle "},{"last_name":"Pitsch","full_name":"Pitsch, Heinz ","first_name":"Heinz "},{"full_name":"Dupont, Sophie","last_name":"Dupont","first_name":"Sophie"},{"last_name":"Kneer","full_name":"Kneer, Reinhold","first_name":"Reinhold"},{"last_name":"Tischendorf","full_name":"Tischendorf, Ricardo","id":"67002","first_name":"Ricardo"},{"last_name":"Massopo","full_name":"Massopo, Orlando","id":"98419","first_name":"Orlando"},{"orcid":"000-0001-8590-1921","last_name":"Schmid","id":"464","full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim"}],"publication":"Applications in Energy and Combustion Science","type":"journal_editor"},{"citation":{"ama":"Massopo O, Schmid H-J, Gonchikzhapov M, Kasper T.

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.

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.

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-graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" xlink:href=\"graphic/j_arh-2022-0140_eq_001.png\" />\r\n                        <m:math xmlns:m=\"http://www.w3.org/1998/Math/MathML\">\r\n                           <m:msub>\r\n                              <m:mrow>\r\n                                 <m:mi>d</m:mi>\r\n                              </m:mrow>\r\n                              <m:mrow>\r\n                                 <m:mi mathvariant=\"normal\">max</m:mi>\r\n                              </m:mrow>\r\n                           </m:msub>\r\n                           <m:mo>=</m:mo>\r\n                           <m:mn>5.5</m:mn>\r\n                           <m:mspace width=\".5em\" />\r\n                           <m:mi mathvariant=\"normal\">mm</m:mi>\r\n                        </m:math>\r\n                        <jats:tex-math>{d}_{{\\rm{\\max }}}=5.5\\hspace{.5em}{\\rm{mm}}</jats:tex-math>\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>"}],"publication":"Applied Rheology","doi":"10.1515/arh-2022-0140","main_file_link":[{"url":"https://www.degruyter.com/document/doi/10.1515/arh-2022-0140/html","open_access":"1"}],"date_updated":"2023-04-27T11:19:08Z","oa":"1","volume":33,"author":[{"first_name":"Sebastian","id":"38243","full_name":"Josch, Sebastian","last_name":"Josch"},{"last_name":"Jesinghausen","orcid":"https://orcid.org/0000-0003-2611-5298","id":"3959","full_name":"Jesinghausen, Steffen","first_name":"Steffen"},{"first_name":"Hans-Joachim","id":"464","full_name":"Schmid, Hans-Joachim","orcid":"000-0001-8590-1921","last_name":"Schmid"}],"intvolume":"        33","citation":{"ama":"Josch S, Jesinghausen S, Schmid H-J.

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."}],"type":"journal_article","publication":"Progress in Additive Manufacturing"},{"publication_status":"published","quality_controlled":"1","year":"2023","citation":{"ieee":"S.

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.","lang":"eng"}],"status":"public","_id":"43046","user_id":"50769","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"},{"_id":"9"}],"keyword":["Selective laser sintering","Shelf life","Polyamide 12","powder","PA2200","material ageing"],"language":[{"iso":"eng"}]},{"publisher":"transcript Verlag","date_updated":"2023-09-08T08:32:42Z","author":[{"first_name":"Dennis","last_name":"Menge","id":"29240","full_name":"Menge, Dennis"},{"full_name":"Milaege, Dennis","last_name":"Milaege","first_name":"Dennis"},{"last_name":"Hoyer","id":"48411","full_name":"Hoyer, Kay-Peter","first_name":"Kay-Peter"},{"last_name":"Schmid","orcid":"000-0001-8590-1921","full_name":"Schmid, Hans-Joachim","id":"464","first_name":"Hans-Joachim"},{"first_name":"Mirko","full_name":"Schaper, Mirko","id":"43720","last_name":"Schaper"}],"date_created":"2023-09-08T08:28:27Z","title":"Case Study IV: Individualized Medical Technology using Additive Manufacturing","doi":"10.14361/9783839463772-007","publication_identifier":{"isbn":["9783837663778","9783839463772"],"issn":["2703-1543","2703-1551"]},"publication_status":"published","place":"Bielefeld, Germany","year":"2023","citation":{"bibtex":"@inbook{Menge_Milaege_Hoyer_Schmid_Schaper_2023, place={Bielefeld, Germany}, title={Case Study IV: Individualized Medical Technology using Additive Manufacturing}, DOI={<a href=\"https://doi.org/10.14361/9783839463772-007\">10.14361/9783839463772-007</a>}, booktitle={Climate Protection, Resource Efficiency, and Sustainable Engineering}, publisher={transcript Verlag}, author={Menge, Dennis and Milaege, Dennis and Hoyer, Kay-Peter and Schmid, Hans-Joachim and Schaper, Mirko}, editor={Horwath, Illona and Schweizer, Swetlana}, year={2023} }","mla":"Menge, Dennis, et al. “Case Study IV: Individualized Medical Technology Using Additive Manufacturing.” <i>Climate Protection, Resource Efficiency, and Sustainable Engineering</i>, edited by Illona Horwath and Swetlana Schweizer, transcript Verlag, 2023, doi:<a href=\"https://doi.org/10.14361/9783839463772-007\">10.14361/9783839463772-007</a>.","short":"D.
