text: Material properties of parts from additive manufacturing are influenced by
a huge number of material, operational and job parameters. This work aims to identify
the most important ones and to investigate mechanical properties as depending
on those parameters. Test specimens were produced with standard PA12 powder on
an EOSINT P390 and P395, respectively. The influence of the orientation and placement
of parts in the building chamber were investigated systematically. The mechanical

text: The aim of this paper is the description and evaluation of physical properties
like porosity and density and their influence on mechanical properties of laser
sintered polyamide parts. For example, by reducing the porosity an increase of
mechanical properties is possible. The correlation of laser parameters to these
properties is investigated in detail. The energy density is an important parameter
for the laser sintering process. By changing laser power, scan velocity and hatch
distance an influence on manufactured components is given. A systematic variation
of all three laser parameters is performed. A comparison of results obtained at
constant energy densities obtained by varying these relevant parameters accordingly
is shown as well.

text: 'Die Entwicklung neuer Konfigurationen zur Rußabscheidung in Elektrofiltern
im Hinblick auf Kfz-Applikationen bedingt die Notwendigkeit, diese auch mithilfe
von Simulationen bewerten zu können. Der Beitrag stellt einen neuen Ansatz zur
Simulation des Abscheideprozesses für einen Temperaturbereich bis 400 Grad C vor.
Entscheidend ist die Möglichkeit, das raumladungsbehaftete elektrische Feld für
alle Betriebszustände zu simulieren. Für den Transport der Raumladungen wird ein
Ansatz aus der Mehrphasenströmungssimulation verwendet. Die Abscheidung der Partikeln
wird mithilfe eines Lagrangeschen Ansatzes modelliert, der die zeitabhängige Aufladung
unter lokalen elektrischen Bedingungen berücksichtigt. Die Simulation des Gesamtprozesses
wird mit experimentellen Untersuchungen anhand eines Laborabscheiders verifiziert.
Simulation und Experiment stimmen gut überein. Insbesondere der dominierende Einfluss
durch die Bereiche in der Nähe der Platten konnte gut abgebildet werden. Das Gleiche
gilt für die parabolische Form der Strom-Spannungs-Kennlinie. Weitere Untersuchungen
sind erforderlich, um die gezeigten Methoden auf die Rußabscheidung zu übertragen.
Die Problematik liegt in der Charakterisierung der Rußeigenschaften in Abhängigkeit
von der Rußentstehung. Auch die Randbedingungen der Methoden zur elektrischen
Charakterisierung können zurzeit noch nicht auf allgemeine Fälle übertragen werden. '

text: Electro-hydrodynamic (EHD) flows are investigated theoretically and numerically
in this paper and results are presented for the flow field in model electrostatic
precipitators (EPs). The resulting flow fields are shown in various representations
and explained qualitatively. Numerical calculations with different flow models
(non-turbulent and RANS) were conducted to investigate the influence of the flow
model on the resulting secondary flows. Furthermore, a perturbation analysis is
presented, leading to a simple differential equation of the Helmholtz type. This
allows a more detailed view of the important mechanisms forming the secondary
flows as well as being able to obtain a very fast estimation of the resulting
flow field. The calculations reveal a strong influence of a vortex formation at
the beginning of the precipitation zone on the whole flow field. Furthermore,
a strong effect of the boundary conditions of the electric field and the operating
parameters is shown.
