Combining all-atom molecular dynamics and capillary simulations we demonstrate that the linear scaling of the interparticle forces with the particle diameter, well established for microscopic and macroscopic particles, can be extended down to diameters of a few nm. At this size scale, however, the molecular nature of the water adsorbates dictates the adhesion forces both via solvation effects and influencing parameters of analytical capillary models such as the equilibrium particle–particle separation distance and the water/particle contact angle. Moreover, the water surface tension becomes considerably larger than the macroscopic bulk value due to combined effects of thin-film confinement and tight curvature, in a way that strongly depends on humidity and particle size. Taking these effects into proper account, classical capillary equations can be used to predict the interparticle forces even of the smallest particles considered here (4 nm), although the circular approximation fails to reproduce the distance at which the water meniscus breaks. Finally, the transition between the dominating effects at the nanoscopic scale and conventional capillary theory valid at microscopic size scales can be only rationalized if the presence of roughness asperities on the surface of the large particles is explicitly taken into account.","lang":"eng"}],"doi":"10.1021/acs.jpcc.7b05655","author":[{"full_name":"Laube, Jens","first_name":"Jens","last_name":"Laube"},{"last_name":"Dörmann","full_name":"Dörmann, Michael","first_name":"Michael"},{"last_name":"Schmid","id":"464","full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim"},{"first_name":"Lutz","full_name":"Mädler, Lutz","last_name":"Mädler"},{"full_name":"Colombi Ciacchi, Lucio","first_name":"Lucio","last_name":"Colombi Ciacchi"}],"title":"Dependencies of the Adhesion Forces between TiO2 Nanoparticles on Size and Ambient Humidity","date_updated":"2022-01-06T06:57:16Z","page":"15294-15303","_id":"26106","status":"public","type":"journal_article","year":"2017","publication_identifier":{"issn":["1932-7447","1932-7455"]},"language":[{"iso":"eng"}],"publication":"The Journal of Physical Chemistry C","date_created":"2021-10-13T13:31:20Z"},{"date_created":"2021-10-13T13:33:31Z","publication":"Powder Technology","language":[{"iso":"eng"}],"type":"journal_article","year":"2017","publication_identifier":{"issn":["0032-5910"]},"status":"public","page":"175-183","_id":"26107","date_updated":"2022-01-06T06:57:16Z","title":"Distance-dependency of capillary bridges in thermodynamic equilibrium","author":[{"last_name":"Dörmann","full_name":"Dörmann, Michael","first_name":"Michael"},{"id":"464","last_name":"Schmid","full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim"}],"abstract":[{"lang":"eng","text":"Capillary forces are very important considering the handling of powders as they, in general, exceed other adhesion forces. These capillary forces are dependent on several different parameters. Especially the distance between the particles is an important parameter. For example, in moving bulk solids a large variety of distances between particles will occur. Therefore, the distance-dependence of capillary bridges was investigated with a numerical simulation method, assuming thermodynamic equilibrium which is attained very fast for small particles. This method uses the Kelvin equation and the Young-Laplace equation to calculate numerically the shape of the capillary bridge without any assumption regarding the shape. The force is eventually derived from the meniscus shape.\r\n\r\nThe distance becomes extremely important when the capillary liquid bridge between two surfaces is only determined by capillary condensation depending on relative humidity. Only a slight increase of the distance within the fraction of a nanometer changes the behaviour of the capillary force significantly. Furthermore, the influence of the force on the separation of particles will be presented. The force decreases almost linearly with increasing distance for a wide range of distances and consequently, a contact stiffness for capillary bridges could be derived. These results may e.g. be used in DEM models. Also, the maximum separation distance of capillary bridges in thermodynamic equilibrium and the correlation with the according bridge volume was investigated. As two limiting cases for capillary bridges at varying distances one can assume either a constant curvature, i.e. infinitely fast attainment of equilibrium, or a constant volume, i.e. infinitely slow attainment of equilibrium. Therefore, a comparison of these two possibilities will be presented and discussed as well."}],"doi":"10.1016/j.powtec.2017.01.012","citation":{"ama":"Dörmann M, Schmid H-J.

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.

This work focuses on temperatures and heat flow within laser sintered part cakes. Therefore, a thermal Finite Element (FE) model of a part cake is developed based on experimental in-process temperature measurements. Thermal boundary conditions and properties of the used bulk polymer powder are analyzed and relevant parameters are identified. The model is validated and optimized considering different job heights and ambient conditions during the cooling phase. It is finally possible to predict position-dependent temperature histories as a function of significant job parameters. The model allows a transfer of the results for varied boundary conditions during cooling.

To this end, we analyzed the velocity field of a strongly shear-thinning fluid, a Newtonian fluid and a set of suspensions via particle image velocimetry in a parallel plate device. Several guard ring sizes were studied. The distortion is described by a simple three parameter model. These parameters are mostly constant for different fluids and suspensions with particle volume fractions below 45%. With increasing radius, the guard ring.s influence approaches a limiting value that we attribute to the influence of the fluid surrounding the gap. Our results indicate a limiting ratio of the difference between plate radius and guard to gap size that should always be exceeded. In the presence of a guard ring, even Newtonian fluids do not exhibit a constant shear rate for most radial distances within the gap.

While most of the previous work focused on layering in Couette cells, the present study aimed to characterize the resulting layers at the plates of a parallel plate rheometer with regard to their relative particle concentration. The particle concentration profile over the radial distance was characterized for various mean concentrations and gap heights. To this end, we mapped the distribution of fluorescently dyed tracer particles in density and refractive index matched suspensions. The results indicate that layering at the surfaces stabilizes as the ratio between gap height and particle diameter increases. For lower gap heights, i.e. as the suspension approaches a two dimensional state, the layer concentration was non-uniform over the plates. In general, results were quantitatively different for the upper and lower plate and the concentration profiles were noticeably asymmetric. We conclude that this is probably the result of the rheometer loading or the start-up process.

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. The results of this work are guidelines for the design and dimensioning of laser sintered lattice structures.","lang":"eng"}],"intvolume":"        27","author":[{"last_name":"Josupeit","first_name":"Stefan","full_name":"Josupeit, Stefan"},{"full_name":"Delfs, Patrick","first_name":"Patrick","last_name":"Delfs"},{"id":"29240","last_name":"Menge","first_name":"Dennis","full_name":"Menge, Dennis"},{"last_name":"Schmid","id":"464","full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim"}],"title":"Manufacturability and Mechanical Characterization of Laser Sintered Lattice Structures","date_updated":"2022-01-06T06:55:28Z","volume":27,"page":"2077-2086","_id":"22180","status":"public","language":[{"iso":"eng"}],"type":"conference","year":"2016","date_created":"2021-05-14T07:46:10Z","publication":"27th Annual International Solid Freeform Fabrication Symposium "},{"user_id":"71545","title":"Optimized build orientation of additive manufactured parts for improved surface quality and build time","abstract":[{"lang":"eng","text":"The layered structure of Additive Manufacturing processes results in a stair- stepping effect of the surface topographies. 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."}],"doi":"10.1016/j.addma.2016.06.003","volume":2,"page":"214-320","issue":"12, Part B","publication":"Additive Manufacturing","type":"journal_article","citation":{"bibtex":"@article{Delfs_Tows_Schmid_2016, title={Optimized build orientation of additive manufactured parts for improved surface quality and build time}, volume={2}, DOI={<a href=\"https://doi.org/10.1016/j.addma.2016.06.003\">10.1016/j.addma.2016.06.003</a>}, number={12, Part B}, journal={Additive Manufacturing}, publisher={Elsevier}, author={Delfs, Patrick and Tows, Marcel and Schmid, Hans-Joachim}, year={2016}, pages={214–320} }","mla":"Delfs, Patrick, et al. “Optimized Build Orientation of Additive Manufactured Parts for Improved Surface Quality and Build Time.” <i>Additive Manufacturing</i>, vol. 2, no. 12, Part B, Elsevier, 2016, pp. 214–320, doi:<a href=\"https://doi.org/10.1016/j.addma.2016.06.003\">10.1016/j.addma.2016.06.003</a>.","short":"P.

For application of the technology in series production and an integration of laser sintered parts into a technical environment, the dimensional accuracy of parts has to be taken into account. Therefore, occurring deviations of the process have to be known to define tolerances for part design. Dimensional deviations and their scattering have to be reduced and homogenized based on process parameters and build job layout. In this work, the dimensional accuracy of laser sintered parts is analyzed for varied parameter values. Influences of different process and geometrical build job parameters on dimensional deviations are figured out. The experimental results allow an evaluation of more and less important influences. Finally, measures are deduced to reduce and homogenize dimensional deviations.","lang":"eng"}],"title":"Geometrische Genauigkeit von Lasersinter-Bauteilen: Einflüsse und Maßnahmen / Dimensional accuracy of polymer laser sintered parts: Influences and measures","editor":[{"full_name":"Kniffka, Wieland","first_name":"Wieland","last_name":"Kniffka"},{"full_name":"Eichmann, Michael","first_name":"Michael","last_name":"Eichmann"},{"last_name":"Witt","first_name":"Gerd","full_name":"Witt, Gerd"},{"full_name":"Josupeit, S.","first_name":"S.","last_name":"Josupeit"},{"first_name":"P.","full_name":"Delfs, P.","last_name":"Delfs"},{"id":"13956","last_name":"Lieneke","first_name":"Tobias","full_name":"Lieneke, Tobias"},{"full_name":"Adam, G.","first_name":"G.","last_name":"Adam"},{"full_name":"Schmid, Hans-Joachim","first_name":"Hans-Joachim","last_name":"Schmid","id":"464","orcid":"000-0001-8590-1921"}]}]
