Exploration of improved, roller-based spreading strategies for cohesive powders in additive manufacturing via coupled DEM-FEM simulations
Reimar Weissbach, Patrick M. Praegla, Wolfgang A. Wall +2
Spreading of fine (D50 <=20um) powders into thin layers typically requires a mechanism such as a roller to overcome the cohesive forces between particles. Roller-based spreading re…
Physics-Based Modeling and Predictive Simulation of Powder Bed Fusion Additive Manufacturing Across Length Scales
Christoph Meier, Sebastian L. Fuchs, Nils Much +10
Powder bed fusion additive manufacturing (PBFAM) of metals has the potential to enable new paradigms of product design, manufacturing and supply chains while accelerating the reali…
A novel smoothed particle hydrodynamics formulation for thermo-capillary phase change problems with focus on metal additive manufacturing melt pool modeling
Christoph Meier, Sebastian L. Fuchs, A. John Hart +1
Laser-based metal processing including welding and three dimensional printing, involves localized melting of solid or granular raw material, surface tension-driven melt flow and si…
Critical Influences of Particle Size and Adhesion on the Powder Layer Uniformity in Metal Additive Manufacturing
Christoph Meier, Reimbar Weissbach, Johannes Weinberg +2
The quality of powder layers, specifically their packing density and surface uniformity, is a critical factor influencing the quality of components produced by powder bed metal add…
Modeling and Characterization of Cohesion in Fine Metal Powders with a Focus on Additive Manufacturing Process Simulations
Christoph Meier, Reimar Weissbach, Johannes Weinberg +2
The cohesive interactions between fine metal powder particles crucially influence their flow behavior, which is in turn important to many powder-based manufacturing processes inclu…
