Powder Directed Energy Deposition Additive Manufacturing - Bead Geometry Modelling

Uploaded May 2024 | Updated September 2026, 2 weeks ago

In this simulation, the Computational Fluid Dynamics (CFD) model of FLOW-3D AM was used to predict the morphology of the bead in DED Additive Manufacturing. The simulation captures the dilution of newly deposited material into the previous layer or substrate. Moreover, the temperature, solid fraction, and velocity inside the melt pool are calculated which gives a detailed picture of the bead formation in this metal 3D printing process. To learn more about how you can use FLOW-3D AM to analyze and predict melt-pool dynamics and solidification in AM processes such as LPBF and DED, visit flow3d.com/products/flow3d-am/.

$Melt Pool Simulation of Overhang Dross in Laser Powder Bed Fusion (LPBF) | FLOW-3D AM This laser powder bed fusion (LPBF) simulation animation shows 3 melt tracks as the laser beam approaches a down-facing overhang surface that runs parallel to the laser motion. The lack of structural support beneath the overhang surface causes the melt pool to sink lower than its neighboring layers, producing an effect called Dross. Naturally, dross formation causes dimensional inaccuracy, high surface roughness and also adversely affects the mechanical properties of printed components. FLOW-3D AM is used to quantify process parameters to reduce defects like dross.
