DEM simulations of the powder coating considering the thermal and mechanical properties of molten areas (B01)

• Subject Area: Mechanical Process Engineering
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 61375930

Sub-project B1 deals with the simulation of the powder recoating process for laser beam melting of polymers. The focus here is the investigation of the recoating mechanism by means of realistic discrete element method (DEM) simulations considering the particle shape and the thermomechanical properties of the powder, as well as the influence of multiple recoated layers and molten region. The aim is to derive optimized time-sensitive recoating strategies and the study of alternative mechanisms that can be tested in practice to improve the quality of the manufactured component.
