Individual and complex parts are directly produced from CAD data without the need of specific tools. The raw material is a polymer powder, which is deposited layerwise and melted selectively with a laser. Built parts are embedded in residual unmolten powder, the so-called part cake, which undergoes thermal ageing effects due to the exposure to high temperatures for long times during the manufacturing process. Hence, the recyclability of the unmolten powder is limited. This article focuses on a fundamental analysis of the ageing kinetics dependent on time, temperature, and oxygen content in the gas atmosphere. A model is developed and applied to measured, position-dependent process temperature histories to successfully predict the ageing distribution within a part cake. The results can be used to optimize the thermal process management in LS and to develop new efficient powder recycling methods.

However, the manufacturability of lattice structures and mechanical properties for polymer laser sintering are quite unknown yet. To examine the manufacturability, sandwich structures with different cell types, cell sizes and lattice bar widths were designed, manufactured and evaluated. A decisive criterion is for example a sufficient powder removal. In a second step, manufacturable structures were analyzed using four-point-bending tests. Experimental data is compared to the density of the lattice structures and allows for a direct comparison of different cell types with varied geometrical attributes.

In general, the impact of this effect strongly depends on the build angle of a surface, whereas the overall surface roughness is additionally 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 all parts of the component surface are equally important, a preselection of areas can be used to improve the overall surface quality of relevant areas. The model uses the digital AMF format of a part. 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 exemplarily with a surface topography simulation for the laser sintering process.","lang":"eng"}],"status":"public","publication":"Additive Manufacturing","type":"journal_article","language":[{"iso":"eng"}],"_id":"22185","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"user_id":"71545"},{"volume":3,"date_created":"2021-05-14T07:46:21Z","author":[{"first_name":"Patrick","last_name":"Delfs","full_name":"Delfs, Patrick"},{"first_name":"Hans-Joachim","last_name":"Schmid","full_name":"Schmid, Hans-Joachim","id":"464"}],"date_updated":"2022-01-06T06:55:28Z","doi":"https://www.bookshop.fraunhofer.de/buch/fraunhofer-direct-digital-manufacturing-conference-ddmc-2016/245111#","title":"Extended Analysis of the Surface Topography of Laser Sintered Polymer Parts ","publication_identifier":{"isbn":["978-3-8396-1001-5"]},"page":"411-414","intvolume":"         3","citation":{"apa":"Delfs, P., &#38; Schmid, H.-J.

Nevertheless, the origin and the evolution are not completely clear yet. Regarding suspensions, the effect becomes even more complicated, because different mechanisms like pure slip or slip due to particle migration have to be taken into account. Furthermore, suspensions themselves show many flow anomalies and the isolation of slip is complicated. In order to develop working physical models, further insight is necessary. In this work, we measured experimentally the wall slip velocities of different highly filled suspensions in a rectangular slit die directly with respect to the particle concentration and the particle size. The slip velocities were obtained using a particle image velocimetry (PIV) system. The suspensions consisting of a castor oil–cinnamon oil blend and PMMA particles were matched in terms of refractive indexes to appear transparent. Hereby, possible optical path lengths larger than 15 mm were achieved. The slip velocities were found to be in a quadratic relation to the wall shear stress. Furthermore, the overall flow rate as well as the particle concentration has a direct influence on the slip. Concerning the shear stress, there seem to be two regions of slip with different physical characteristics. Furthermore, we estimated the slip layer thickness directly from the velocity profiles and propose a new interpretation. The PIV technique is used to investigate the viscosity and implicit the concentration profile in the slit die. It is shown that the particle migration process is quite fast.","lang":"eng"}],"status":"public","_id":"21947","user_id":"3959","department":[{"_id":"150"},{"_id":"9"}],"article_type":"original","keyword":["Rheology","Wall Slip","Slip","apparent slip","suspension"],"language":[{"iso":"eng"}]},{"publisher":"Shaker Verlag","date_updated":"2023-01-27T12:14:45Z","date_created":"2023-01-27T10:47:41Z","author":[{"first_name":"Sascha","last_name":"Schiller","full_name":"Schiller, Sascha"}],"title":"Zur Feinstaubabscheidung aus Holzfeuerungsanlagen mit precoatierten Oberflächenfiltern","publication_identifier":{"isbn":["978-3-8440-4342-6"]},"year":"2016","citation":{"ieee":"S.

Über eine definierte Qualitätsprozesskette werden sämtliche, auf die Produktqualität relevanten Einflussparameter, bestimmt und berücksichtigt. Unterschiedliche Methoden zur Materialcharakterisierung des pulverförmigen Ausgangsmaterials werden analysiert und bewertet. 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.

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."}],"status":"public","_id":"22179","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"user_id":"71545","language":[{"iso":"eng"}],"year":"2015","intvolume":"        26","page":"190-199","citation":{"apa":"Josupeit, S., &#38; Schmid, H.-J.

Hence, it needs to be refreshed with new material for further build cycles. In application, refresh rates of about 50 % are commonly used. In this work, the recycling optimized material PA 2221 from EOS is analyzed along a series of 13 build and refresh cycles using a reduced refresh rate of 32 %. 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. As a result, process conditions of PA 2221 using reduced refresh rates can be derived from this work.","lang":"eng"}],"type":"conference","publication":"26th Annual International Solid Freeform Fabrication Symposium","language":[{"iso":"eng"}],"user_id":"71545","department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"_id":"22187","citation":{"ama":"Josupeit S, Lohn J, Hermann E, Gessler M, Tenbrink S, Schmid H-J.
