Dies gilt auch für das hier betrachtete Laserstrahlschmelzen, bei dem metallische Werkstoffe in Pulverform verarbeitet werden. Durch den schichtweisen Aufbau können dabei enorme Vorteile gegenüber konventionellen Fertigungsverfahren erzielt werden, was sich u. a. in einem bis dato unerreichten Maß an Geometriefreiheit widerspiegelt.\r\n\r\nAllerdings werden die Werkstoffeigenschaften teils erheblich durch kurze und intensive Wechselwirkungen zwischen Laser und Werkstoff bestimmt. Hierdurch können sich werkstoff-spezifische Nachteile gegenüber konventionellen Fertigungsverfahren ergeben, die eine weitreichende Etablierung des Laserstrahlschmelzens erschweren.\r\n\r\nVor diesem Hintergrund zielt die vorliegende Dissertation auf eine Analyse und ggf. Optimierung der mikrostrukturellen und mechanischen Eigenschaften laserstrahlgeschmolzener Werkstoffe. Der Schwerpunkt liegt hierbei auf einer Ermüdungsbeanspruchung, da Einflüsse prozess-induzierter Defektstrukturen unter dieser Beanspruchungsform besonders deutlich werden. Durch umfangreiche Untersuchungen können dabei Prozessrouten aufgezeigt werden, die für die betrachteten Werkstoffe TiAl6V4 und 316L den detektierten Schädigungsmechanismen Rechnung tragen und somit zu einer technologischen Konkurrenzfähigkeit des Laserstrahlschmelzens führen.","lang":"eng"}],"title":"Einfluss prozess-induzierter Defekte auf die Ermüdungseigenschaften metallischer Werkstoffe verarbeitet mittels Laserstrahlschmelzen","publisher":"Düren Verlag GmbH","date_created":"2021-09-23T09:19:37Z","year":"2016"},{"user_id":"71545","series_title":"Forschungsberichte des Direct Manufacturing Research Centers","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"_id":"24751","type":"dissertation","status":"public","author":[{"first_name":"Stefan","full_name":"Rüsenberg, Stefan","last_name":"Rüsenberg"}],"supervisor":[{"last_name":"Schmid","full_name":"Schmid, Hans-Joachim","id":"464","first_name":"Hans-Joachim"}],"volume":"Band, 2","date_updated":"2022-01-06T06:56:33Z","main_file_link":[{"url":"https://www.shaker.de/de/content/catalogue/index.asp?lang=de&ID=8&ISBN=978-3-8440-3507-0&search=yes"}],"publication_status":"published","publication_identifier":{"unknown":["978-3-8440-3507-0"]},"citation":{"chicago":"Rüsenberg, Stefan. <i>Prozessqualifizierung zur verlässlichen Herstellung von Produkten im Polymer Lasersinterverfahren</i>.

Über eine definierte Qualitätsprozesskette werden sämtliche, auf die Produktqualität relevanten Einflussparameter, bestimmt und berücksichtigt.

Rheologische sowie chemische Eigenschaften, aber auch die Partikelgrößenverteilung oder die Schüttdichte werden hinsichtlich Relevanz, Einfluss und Anwenderfreundlichkeit untersucht. Das Ziel ist eine sinnvolle Bestimmung des Ausgangszustandes des Pulvers anhand definierter, relevanter Materialeigenschaften, um reproduzierbare technische Bauteileigenschaften zu gewährleisten. Dazu werden mechanische, dynamisch-mechanische, physikalische, elektrische, thermische sowie chemische Untersuchungen durchgeführt und hinsichtlich wichtiger Einflussparameter evaluiert. Die Bestimmung erfolgt über entwickelte Referenzjobs, in denen die hauptsächlichen Einflussfaktoren auf das Polymer-Lasersinterverfahren entlang der Qualitätsprozesskette berücksichtigt werden. Die charakterisierten Daten dienen zur Auslegung eines fiktiven Produktes aus der Luftfahrtindustrie. Mit Hilfe dieser Methoden lassen sich Materialkennwerte für diverse Simulationstools eindeutig bestimmen um eine realitätsnahe Berechnung zu gewährleisten.

In this work, a measurement system for three-dimensional in-process temperature measurements is set up and the influence of different parameters on the inner part cake temperature distribution and history is analyzed. Important factors are not only geometrical build job parameters like the part packing density and build height, but also process parameters like the layer thickness and bulk powder density. Individual in-process temperature profiles at different positions within a part cake are finally correlated with powder ageing effects. The results of this work help to understand the temperature history dependency of powder and part properties and can therefore be used to develop optimized process controls.","lang":"eng"}],"date_created":"2021-05-14T07:46:09Z","author":[{"first_name":"Stefan","full_name":"Josupeit, Stefan","last_name":"Josupeit"},{"last_name":"Schmid","id":"464","full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim"}],"volume":26,"date_updated":"2022-01-06T06:55:28Z","doi":"http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-15-Josupeit.pdf","title":"Temperature History within Laser Sintered Part Cakes and its Influence on Process Quality","citation":{"short":"S.

Before and after every build, the powder is analyzed regarding melt properties determined by MVR and DSC measurements. Thereby, in-process ageing effects are investigated and the steady-state conditions are determined accordingly. In addition, powder properties are directly linked to resulting mechanical and geometrical part properties. Key findings are a robust DSC measurement method for polyamide 12 powder, constant “circulated” material properties after three build/refresh cycles and robust tensile properties along the whole tested powder life cycle.

In general the impact of this effect strongly depends on the build angle of a surface, whereas the overall surface roughness is caused by the resolution of the specific AM process. The aim of this work is the prediction of the surface quality in dependence of the building orientation of a part. These results can finally be used to optimize the orientation to get a desired surface quality. As not every area of a part can be optimized, a predetermination of areas can be used to improve the surface quality of important areas. The model uses the digital STL format of a part as this is necessary for all AM machines to build it. Each triangle is assigned with a roughness value and by testing different orientations the best one can be found. This approach needs a database for the surface qualities. This must be done separately for each Additive Manufacturing process and is shown exemplary with a surface topography simulation for the laser sintering process.","lang":"eng"}],"type":"conference","publication":"26th Annual International Solid Freeform Fabrication Symposium"},{"page":"63-78","citation":{"bibtex":"@inproceedings{Josupeit_Tutzschky_Gessler_Schmid_2015, title={Powder ageing and material properties of laser sintered polyamide 12 using low refresh rates}, DOI={<a href=\"https://doi.org/10.1007/978-3-662-48473-9_5\">10.1007/978-3-662-48473-9_5</a>}, booktitle={Proceedings of the Rapid Tech 2015}, publisher={Springer Vieweg}, author={Josupeit, Stefan and Tutzschky, S. and Gessler, M. and Schmid, Hans-Joachim}, year={2015}, pages={63–78} }","mla":"Josupeit, Stefan, et al. “Powder Ageing and Material Properties of Laser Sintered Polyamide 12 Using Low Refresh Rates.” <i>Proceedings of the Rapid Tech 2015</i>, Springer Vieweg, 2015, pp. 63–78, doi:<a href=\"https://doi.org/10.1007/978-3-662-48473-9_5\">10.1007/978-3-662-48473-9_5</a>.","short":"S.

Design/methodology/approach – First, a process-independent method for the development of Design Rules was worked out. Therefore, geometrical standard elements and attributes that characterize the elements’ shapes have been defined. Next, the standard elements have been manufactured with different attribute values with Laser Sintering, Laser Melting and Fused Deposition Modeling, and their geometrical quality was examined. From the results, Design Rules for additive manufacturing were derived and summarized in a catalogue. Findings – Due to the process independent method, Design Rules were developed that apply for the different considered additive manufacturing technologies equally. These Design Rules are completely function-independent and easily transferable to individual part designs. Research limitations/implications – The developed Design Rules can only apply for the considered boundary conditions. To extend the Design Rules’ validity, their applicability should be proven for other boundary conditions. Practical implications – The developed Design Rules practically support the design of technical parts. Additionally they can be used for training and teaching in the field of “design for additive manufacturing”. Originality/value – The developed Design Rules constitute a first step toward general Design Rules for Additive Manufacturing. Thus, they might form a suitable basis for further scientific approaches, and the Design Rules can be used to set up teaching documentations for lessons and seminars."}],"type":"journal_article","publication":"Rapid Prototyping Journal"},{"title":"Entwicklung einer Methode zur systematischen Erarbeitung von Maßtoleranzen für additive Fertigungsverfahren","date_updated":"2022-01-06T06:55:32Z","date_created":"2021-06-15T11:09:21Z","author":[{"first_name":"Tobias","last_name":"Lieneke","full_name":"Lieneke, Tobias"},{"first_name":"Guido","last_name":"Adam","full_name":"Adam, Guido"},{"full_name":"Leuders, Stefan","last_name":"Leuders","first_name":"Stefan"},{"full_name":"Knoop, Frederick","last_name":"Knoop","first_name":"Frederick"},{"last_name":"Josupeit","full_name":"Josupeit, Stefan","first_name":"Stefan"},{"last_name":"Delfs","full_name":"Delfs, Patrick","first_name":"Patrick"},{"first_name":"Nils","full_name":"Funke, Nils","last_name":"Funke"},{"first_name":"Detmar","full_name":"Zimmer, Detmar","id":"604","last_name":"Zimmer"}],"year":"2015","citation":{"ama":"Lieneke T, Adam G, Leuders S, et al.

In order to profit from these benefits, it is necessary to consider the manufacturing limits and restrictions. This applies in particular to the geometrical accuracy. Therefore, the achievable geometrical accuracy needs to be investigated, which enables the determination of realistic tolerances. Thus, two different aims are considered. The first aim is the determination of dimensional tolerances that can be stated if additive manufacturing is used under normal workshop conditions. Within the second aim, relevant process parameters and manufacturing influences will be optimized in order to reduce dimensional deviations. To achieve both aims a method was developed first. This method identifies relevant influential factors on the geometrical accuracy for the processes Fused Deposition Modeling (FDM), Laser Sintering (LS) and Laser Melting (LM). Factors were selected that are expected to affect the geometrical accuracy mainly. The first investigations deal with measuring linear dimensions on a designed test specimen and the derivation of achievable dimensional tolerances. This paper will present both, the developed method and the first results of the experimental investigations."}],"type":"conference","publication":"26th Annual International Solid Freeform Fabrication Symposium","language":[{"iso":"eng"}],"user_id":"38077","department":[{"_id":"9"},{"_id":"146"},{"_id":"219"},{"_id":"624"},{"_id":"367"},{"_id":"150"}],"_id":"22396"},{"status":"public","type":"dissertation","language":[{"iso":"eng"}],"_id":"22397","department":[{"_id":"9"},{"_id":"146"},{"_id":"219"},{"_id":"624"}],"user_id":"38077","year":"2015","citation":{"apa":"Adam, G.
