Macroscopic modeling, simulation, and optimization of the selective beam melting process (C3)

(Third Party Funds Group – Sub project)

Overall project: CRC 814 - Additive Manufacturing
Project leader: Julia Mergheim
Start date: 1. July 2011
End date: 30. June 2023
Acronym: SFB 814 (C3)
Funding source: DFG / Sonderforschungsbereich (SFB)

Abstract:

The aim of the sub-project is to extend the simulationtool for LSS-K, LSS-M and SEBM from the first two funding periods to ahierarchical simulation environment in order to develop and qualify problem-and parts-adapted simulation strategies. This requires the application ofreduced physical models, compensation strategies for error reduction andefficient algorithms, e.g. adaptive multi-rate time integrators. The processsimulations (for parts up to 1000 cm³) will support the processcontrol for the reproducible production of parts with defined properties.
