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.

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."}],"publication":"Proceedings of the 34th Annual International Solid Freeform Fabrication Symposium","doi":"https://doi.org/10.26153/tsw/50926","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.sffsymposium.org/","open_access":"1"}],"publication_status":"published","date_updated":"2024-04-02T12:43:51Z","author":[{"id":"72307","last_name":"Neitzel","orcid":"0009-0004-8412-3645 ","first_name":"Fabian","full_name":"Neitzel, Fabian"},{"id":"50769","last_name":"Kletetzka","first_name":"Ivo","full_name":"Kletetzka, Ivo"},{"orcid":"000-0001-8590-1921","last_name":"Schmid","first_name":"Hans-Joachim","full_name":"Schmid, Hans-Joachim","id":"464"}],"year":"2023","title":"Halogen-Free Flame Retardant Powder Materials for Laser Sintering: Evaluation and Process Stability Analysis"},{"oa":"1","citation":{"mla":"Josch, Sebastian, et al. “Experimental and Simulative Determination and Correction of the Effective Gap Extension in Structured Coaxial Measuring Systems.” <i>Rheologica Acta</i>, Springer Science and Business Media LLC, 2023, doi:<a href=\"https://doi.org/10.1007/s00397-023-01383-2\">10.1007/s00397-023-01383-2</a>.","bibtex":"@article{Josch_Jesinghausen_Dechert_Schmid_2023, title={Experimental and simulative determination and correction of the effective gap extension in structured coaxial measuring systems}, DOI={<a href=\"https://doi.org/10.1007/s00397-023-01383-2\">10.1007/s00397-023-01383-2</a>}, journal={Rheologica Acta}, publisher={Springer Science and Business Media LLC}, author={Josch, Sebastian and Jesinghausen, Steffen and Dechert, Christopher and Schmid, Hans-Joachim}, year={2023} }","ama":"Josch S, Jesinghausen S, Dechert C, Schmid H-J.

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>"}],"issue":"1","publication":"Applied Rheology","doi":"10.1515/arh-2022-0140","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://www.degruyter.com/document/doi/10.1515/arh-2022-0140/html"}],"intvolume":"        33","date_updated":"2023-04-27T11:19:08Z","publication_status":"published","author":[{"id":"38243","last_name":"Josch","first_name":"Sebastian","full_name":"Josch, Sebastian"},{"last_name":"Jesinghausen","first_name":"Steffen","orcid":"https://orcid.org/0000-0003-2611-5298","full_name":"Jesinghausen, Steffen","id":"3959"},{"orcid":"000-0001-8590-1921","first_name":"Hans-Joachim","last_name":"Schmid","full_name":"Schmid, Hans-Joachim","id":"464"}],"publication_identifier":{"issn":["1617-8106"]},"title":"Development of an adaptive coaxial concrete rheometer and rheological characterisation of fresh concrete","year":"2023"},{"doi":"10.1016/j.powtec.2023.118460","language":[{"iso":"eng"}],"article_number":"118460","intvolume":"       422","date_updated":"2023-04-27T12:33:28Z","publication_status":"published","publication_identifier":{"issn":["0032-5910"]},"author":[{"id":"38188","full_name":"Rüther, Moritz Johannes","first_name":"Moritz Johannes","last_name":"Rüther"},{"full_name":"Klippstein, Sven Helge","first_name":"Sven Helge","last_name":"Klippstein","id":"71545"},{"full_name":"Ponusamy, SathishKumar","last_name":"Ponusamy","first_name":"SathishKumar","id":"77383"},{"id":"76950","full_name":"Rüther, Torben","first_name":"Torben","last_name":"Rüther"},{"orcid":"000-0001-8590-1921","last_name":"Schmid","first_name":"Hans-Joachim","full_name":"Schmid, Hans-Joachim","id":"464"}],"year":"2023","title":"Flowability of polymer powders at elevated temperatures for additive manufacturing","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"type":"journal_article","keyword":["General Chemical Engineering"],"date_created":"2023-03-27T19:57:12Z","publication":"Powder Technology","volume":422,"user_id":"71545","_id":"43128","publisher":"Elsevier BV","status":"public","quality_controlled":"1","citation":{"mla":"Rüther, Moritz Johannes, et al. “Flowability of Polymer Powders at Elevated Temperatures for Additive Manufacturing.” <i>Powder Technology</i>, vol. 422, 118460, Elsevier BV, 2023, doi:<a href=\"https://doi.org/10.1016/j.powtec.2023.118460\">10.1016/j.powtec.2023.118460</a>.","bibtex":"@article{Rüther_Klippstein_Ponusamy_Rüther_Schmid_2023, title={Flowability of polymer powders at elevated temperatures for additive manufacturing}, volume={422}, DOI={<a href=\"https://doi.org/10.1016/j.powtec.2023.118460\">10.1016/j.powtec.2023.118460</a>}, number={118460}, journal={Powder Technology}, publisher={Elsevier BV}, author={Rüther, Moritz Johannes and Klippstein, Sven Helge and Ponusamy, SathishKumar and Rüther, Torben and Schmid, Hans-Joachim}, year={2023} }","ama":"Rüther MJ, Klippstein SH, Ponusamy S, Rüther T, 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.","lang":"eng"}],"date_created":"2023-09-06T06:49:38Z","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"},{"_id":"9"}],"type":"journal_article","keyword":["Industrial and Manufacturing Engineering"],"status":"public","publisher":"Springer Science and Business Media LLC","_id":"46815","user_id":"50769","citation":{"mla":"Kletetzka, Ivo, et al. “Influence of the Filler–Matrix Adhesion and the Effects of Conditioning on Tensile Properties of Laser-Sintered Parts Built with Polyamide–Glass Bead Dry Blends.” <i>Progress in Additive Manufacturing</i>, Springer Science and Business Media LLC, 2023, doi:<a href=\"https://doi.org/10.1007/s40964-023-00501-z\">10.1007/s40964-023-00501-z</a>.","ama":"Kletetzka I, Kosanke M, Meinderink D, Neßlinger V, Grundmeier G, Schmid H-J.

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"}],"publication":"The International Journal of Advanced Manufacturing Technology "},{"publication_status":"published","date_updated":"2023-09-08T08:32:42Z","author":[{"full_name":"Menge, Dennis","last_name":"Menge","first_name":"Dennis","id":"29240"},{"first_name":"Dennis","last_name":"Milaege","full_name":"Milaege, Dennis"},{"full_name":"Hoyer, Kay-Peter","last_name":"Hoyer","first_name":"Kay-Peter","id":"48411"},{"last_name":"Schmid","first_name":"Hans-Joachim","orcid":"000-0001-8590-1921","full_name":"Schmid, Hans-Joachim","id":"464"},{"id":"43720","last_name":"Schaper","first_name":"Mirko","full_name":"Schaper, Mirko"}],"publication_identifier":{"issn":["2703-1543","2703-1551"],"isbn":["9783837663778","9783839463772"]},"year":"2023","status":"public","title":"Case Study IV: Individualized Medical Technology using Additive Manufacturing","editor":[{"full_name":"Horwath, Illona","last_name":"Horwath","first_name":"Illona"},{"first_name":"Swetlana","last_name":"Schweizer","full_name":"Schweizer, Swetlana"}],"user_id":"48411","doi":"10.14361/9783839463772-007","publisher":"transcript Verlag","_id":"46870","language":[{"iso":"eng"}],"citation":{"ieee":"D.

For this purpose, micro glass spheres, hollow glass bubbles and mineral spheres are dry blended to the matrix polymers polyamide 613 and polypropylene with a filling ratio of 20 and 40 vol%. First, relevant properties of the blends, such as powder flowability, thermal behavior and melt viscosity, are investigated. Based on the results, processing parameters are then developed for the LS process and the mechanical properties of the components are investigated. The aim is to be able to tailor the mechanical properties of LS components by adding fillers and thus to create new application areas for additively manufactured components.
