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."}],"citation":{"ama":"Rüsenberg S, Schmidt L, Schmid H-J.

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.

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.
