[{"abstract":[{"text":"The process-related occurrence of varying cooling rates at different positions within the part cake is an important challenge regarding the part quality and reproducibility of the polymer laser sintering process. Temperature history dependent parameters are for example the part warpage, the crystallization behavior or powder ageing effects, which have to be considered for optimized process controls. Nevertheless, the inner temperature distribution and history during the cooling process is difficult to measure and less known yet. In this work, a Finite Element (FE) model is developed to understand and predict the temperature distribution and history within the part cake during the cooling process. Therefore, the thermal boundary conditions of a laser sintering system are analyzed and relevant parameters are identified. A basic FE model is set up in ABAQUS CAE software considering a part-free powder cake. Important thermal parameters of the bulk powder and the environment are adjusted and verified in relation to experimental in-process measured data. With this model it is possible to predict position-dependent cooling rates as a function of significant job parameters, for example the job height or the environmental conditions during the cooling phase. In combination with extended in-process temperature measurements and a consideration of built parts, this model will be an important tool for the development of optimized process controls.","lang":"eng"}],"publication":"International Conference on Additive Technologies","citation":{"ieee":"S.

Profound changings of the existing processes can be expected for the area of Maintenance, Repair and Overhaul (MRO) as well. It is described with the help of scenarios which chances result from the integration of this technology while different applications are considered. It starts with the implementation of AM as another manufacturing technology for the repair of spare parts. The precision reduces the effort for post-processing in comparison to the conventional manufacturing methods such as the build-up welding. If an unexpected part breakdown occurs and the aircraft has to stay on ground, there are high demands on the logistics to deliver the required spare parts from the warehouse as fast as possible. The storage of spare parts causes extremely high costs and can be considerably reduced with the help of Additive Manufacturing.

This is due to the characteristics of the process. In many fields of application, high demands are made on the optical quality of the part. An improvement in the surface quality of FDM parts made of Ultem*9085 can be achieved through post-treatment with a mass finishing process. In this paper, FDM specimens are post-treated in a disk finishing unit. Influences of the mass finishing process are analyzed with regard to the dependence of surface quality on the various process parameters and on the finishing medium, grinding time and grinding speed. The finishing efficiency depends on the finishing media and decreases for lower finishing time. For all media a lower disk velocity results a smaller grinding effect, but there are clearly differences between the finishing media. The paper also discusses effects of the grinding process on the mechanical properties of the parts. Especially small part geometries and parts build in z-direction tend to break during the finishing process.","lang":"eng"}],"quality_controlled":"1","citation":{"ama":"Fischer M, Schöppner V.

Furthermore, lightweight parts with specific inner core structures can be manufactured in order to achieve good weightrelated strength properties. In this paper the mechanical behavior of lightweight parts manufactured with the 3D production system Fortus 400mc from Stratasys and the material Polyetherimide (PEI) with the trade name Ultem*9085 is analyzed. The test specimens were built up with different inner structures and building directions. Therefore, test specimens with known lightweight core geometries (e.g. corrugated and honeycomb cores) were designed. A four-point bending test was conducted to analyze the strength properties as well as the weight-related strength properties. Additionally the influence of the structure width, the structure wall thickness and the top layer thickness was analyzed using a honeycomb structure."}],"quality_controlled":"1","date_created":"2021-05-07T13:23:00Z","type":"conference","department":[{"_id":"219"},{"_id":"624"},{"_id":"367"},{"_id":"321"},{"_id":"9"}],"year":"2014","title":"Mechanical Analysis of Lightweight Constructions manufactured with Fused Deposition Modeling","status":"public","author":[{"full_name":"Bagsik, A.","first_name":"A.","last_name":"Bagsik"},{"first_name":"S.","last_name":"Josupeit","full_name":"Josupeit, S."},{"first_name":"Volker","last_name":"Schöppner","full_name":"Schöppner, Volker","id":"20530"},{"first_name":"E.","last_name":"Klemp","full_name":"Klemp, E."}],"date_updated":"2022-04-25T08:05:29Z","intvolume":"        29","page":"696-701","publisher":"American Institute of Physics ","_id":"22021","language":[{"iso":"eng"}],"doi":"10.1063/1.4873874","user_id":"70729","volume":29},{"date_updated":"2024-03-27T15:25:07Z","publication_status":"published","publication_identifier":{"issn":["0884-2914","2044-5326"]},"author":[{"last_name":"Leuders","first_name":"Stefan","full_name":"Leuders, Stefan"},{"id":"13956","full_name":"Lieneke, Tobias","last_name":"Lieneke","first_name":"Tobias"},{"first_name":"Stefan","last_name":"Lammers","full_name":"Lammers, Stefan","id":"13835"},{"full_name":"Tröster, Thomas","last_name":"Tröster","first_name":"Thomas","id":"553"},{"first_name":"Thomas","last_name":"Niendorf","full_name":"Niendorf, Thomas"}],"year":"2014","title":"On the fatigue properties of metals manufactured by selective laser melting – The role of ductility","status":"public","doi":"10.1557/jmr.2014.157","user_id":"13956","_id":"15965","language":[{"iso":"eng"}],"page":"1911-1919","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title><jats:p><jats:fig position=\"anchor\"><jats:graphic xmlns:xlink=\"http://www.w3.org/1999/xlink\" orientation=\"portrait\" mime-subtype=\"jpeg\" mimetype=\"image\" position=\"float\" xlink:type=\"simple\" xlink:href=\"S0884291414001575_figAb\" /></jats:fig></jats:p>"}],"citation":{"mla":"Leuders, Stefan, et al. “On the Fatigue Properties of Metals Manufactured by Selective Laser Melting – The Role of Ductility.” <i>Journal of Materials Research</i>, 2014, pp. 1911–19, doi:<a href=\"https://doi.org/10.1557/jmr.2014.157\">10.1557/jmr.2014.157</a>.","bibtex":"@article{Leuders_Lieneke_Lammers_Tröster_Niendorf_2014, title={On the fatigue properties of metals manufactured by selective laser melting – The role of ductility}, DOI={<a href=\"https://doi.org/10.1557/jmr.2014.157\">10.1557/jmr.2014.157</a>}, journal={Journal of Materials Research}, author={Leuders, Stefan and Lieneke, Tobias and Lammers, Stefan and Tröster, Thomas and Niendorf, Thomas}, year={2014}, pages={1911–1919} }","ama":"Leuders S, Lieneke T, Lammers S, Tröster T, Niendorf T.

The amount of used powder, which is not sintered, can be refreshed and used for further building jobs. Due to cost reduction, better mechanical properties and a simpler processing it is reasonable to combine virgin and used powder for part manufacturing. During the building time the powder is thermally loaded and its structure is changed. State of the art in laser sintering is a defined powder ratio. Since the powder ageing depends on the individual history of sintering, this procedure cannot ensure a defined powder quality. However, for a serial production it is necessary to characterize the raw material, as well as all other steps along the process chain, in order to ensure a high reproducibility and reliability. Rheological, physical and particle properties are considered to correlate powder and chosen material properties. Different powder qualities adjusted by the Melt Volume Rate (MVR) are tested using promising rheological properties like viscosity or molecular weight. Investigations about powder bed density, bulk properties as well as thermal characterization complement the experimental setup. These parameters are correlated with mechanical, electrical, thermal and physical material properties of laser sintered parts. The most important influencing factors along the process chain are kept constant. At the end a procedure is shown to obtain a defined powder quality. This procedure will be transferred to other materials and will be tested using other laser sintering machines of the same type as well as other types."}],"date_created":"2021-05-14T07:46:24Z","type":"conference","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"year":"2013","status":"public","title":"Advanced characterization method of Nylon 12 materials for application in laser sinter processing","author":[{"first_name":"Stefan","last_name":"Rüsenberg","full_name":"Rüsenberg, Stefan"},{"first_name":"Hans-Joachim","last_name":"Schmid","full_name":"Schmid, Hans-Joachim","id":"464"}],"date_updated":"2022-01-06T06:55:28Z","intvolume":"        29","_id":"22192","language":[{"iso":"eng"}],"doi":"10.1063/1.4873877","user_id":"71545","volume":29},{"department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"type":"conference","date_created":"2021-05-14T07:46:29Z","citation":{"mla":"Josupeit, Stefan, et al. “Mechanische Und Rheologische Untersuchungen Neuer Laser Sinter Materialien.” <i>Merseburger Rapid Prototyping Forum</i>, vol. 7, 2013, doi:<a href=\"https://www.rp-netzwerk.de/images/stories/pdf/rapid_7/Universitaet_Paderborn_DMRC_RP-Forum2013.pdf\">https://www.rp-netzwerk.de/images/stories/pdf/rapid_7/Universitaet_Paderborn_DMRC_RP-Forum2013.pdf</a>.","bibtex":"@inproceedings{Josupeit_Rüsenberg_Schmid_2013, title={Mechanische und rheologische Untersuchungen neuer Laser Sinter Materialien}, volume={7}, DOI={<a href=\"https://www.rp-netzwerk.de/images/stories/pdf/rapid_7/Universitaet_Paderborn_DMRC_RP-Forum2013.pdf\">https://www.rp-netzwerk.de/images/stories/pdf/rapid_7/Universitaet_Paderborn_DMRC_RP-Forum2013.pdf</a>}, booktitle={Merseburger Rapid Prototyping Forum}, author={Josupeit, Stefan and Rüsenberg, Stefan and Schmid, Hans-Joachim}, year={2013} }","ama":"Josupeit S, Rüsenberg S, Schmid H-J.
