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"}]},{"type":"conference","publication":"25th Annual International Solid Freeform Fabrication Symposium","status":"public","abstract":[{"lang":"eng","text":"One barrier of laser sintering (LS) to become the main process for Direct Manufacturing (DM) is the surface quality of LS parts.

The transfer is based on the adsorption of surfactants onto the particle surface at the liquid–liquid interface. While penetrating the liquid–liquid interface, the particles are covered with surfactants and a partial de-agglomeration is initiated.

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.","lang":"eng"}],"publication":"International Conference of the Polymer-Processing-Society (PPS)","type":"conference","language":[{"iso":"eng"}],"department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"user_id":"71545","_id":"22192"},{"language":[{"iso":"eng"}],"department":[{"_id":"150"},{"_id":"624"},{"_id":"219"}],"user_id":"71545","_id":"22197","status":"public","publication":"Merseburger Rapid Prototyping Forum","type":"conference","doi":"https://www.rp-netzwerk.de/images/stories/pdf/rapid_7/Universitaet_Paderborn_DMRC_RP-Forum2013.pdf","title":"Mechanische und rheologische Untersuchungen neuer Laser Sinter Materialien","volume":7,"date_created":"2021-05-14T07:46:29Z","author":[{"first_name":"Stefan","last_name":"Josupeit","full_name":"Josupeit, Stefan"},{"first_name":"Stefan","full_name":"Rüsenberg, Stefan","last_name":"Rüsenberg"},{"first_name":"Hans-Joachim","last_name":"Schmid","id":"464","full_name":"Schmid, Hans-Joachim"}],"date_updated":"2022-01-06T06:55:28Z","intvolume":"         7","citation":{"apa":"Josupeit, S., Rüsenberg, S., &#38; Schmid, H.-J.

The model accounts for the full aerosol process, including chemical reaction, nucleation from supersaturated vapor, growth and agglomeration. The results are in good agreement with experimental data. The effects of the process parameters temperature, silane concentration and reactor total pressure are systematically investigated. The simulation allows an in-depth insight into the particle formation mechanism and reveals the key requirements which are necessary for the generation of narrow particle size distributions. In this mechanism, only a short nucleation burst occurs, while surface growth plays the dominant role in silane precursor consumption.

The size of the particles could be precisely controlled in the range of 20–40 nm, whilst maintaining a geometric standard deviation in the range of 1.06–1.08, by proper choice of the governing parameters temperature, residence time and precursor concentration. The results show that narrow particle size distributions can only be obtained in the temperature range between 900 and 1100 °C, as long as both the initial silane concentration (1 mbar silane partial pressure) and the reactor total pressure are low (25 mbar).

The study revealed a high sensitivity of the system with respect to the modeling of intrinsic parameters, motivating a comprehensive validation of the estimates. In the forward simulation the impact of the influencing parameters including surface energy, nucleus size and distribution is investigated. Subsequently we construct a simplified model of the precipitation process in such a way that it is orbitally flat in terms of control theory, which enables the inverse calculation of the parameters. The numerical results of the inverse simulation for the interfacial energy have been compared to a physical model. The possibility of solving the inverse problem provides a promising way of estimating hardly measurable quantities for more complex molecules.","lang":"eng"}],"user_id":"70093","_id":"26137","language":[{"iso":"eng"}],"issue":"6","publication_identifier":{"issn":["0009-2509"]},"publication_status":"published","intvolume":"        65","page":"2183-2189","citation":{"apa":"Vassilev, V., Gröschel, M., Schmid, H.-J., Peukert, W., &#38; Leugering, G.
