Adhesion effects on spreading of metal powders in selective laser melting
TL;DR: In this article, a discrete element method (DEM) model is used to examine the powder spreading process, focusing on the effects of particle adhesion and particle-based behaviors, and the results show that particle adhesiveness can reduce powder packing density and smoothness of the powder bed surface.
Journal ArticleDOI
Effects of spreader geometry on powder spreading process in powder bed additive manufacturing
TL;DR: In this paper, the effects of various spreader geometries on powder spreading are examined by discrete element method (DEM) and the results show that a compact region in the powder pile exists.
Journal ArticleDOI
Particle scale modelling of melt pool dynamics and pore formation in selective laser melting additive manufacturing
TL;DR: In this paper, a validated mathematical model is employed to assess effect of material properties such as powder melting and solidification coefficients and mushy zone constant and the results indicate that a large solidification rate is preferred to avoid the pore defect and surface cavity.
Journal ArticleDOI
Numerical studies of melt pool and gas bubble dynamics in laser powder bed fusion process
TL;DR: In this article , through modeling the metal powder melting and subsequent solidification under the conduction mode, it was found that the molten liquid near the gas-liquid interface flows centrifugally and vortices including a clockwise and an anticlockwise vortex are produced.
Journal ArticleDOI
Powder deposition mechanism during powder spreading with different spreader geometries in powder bed fusion additive manufacturing
TL;DR: In this paper, a discrete element method is used to examine the mechanisms determining powder deposition efficiency during powder spreading in powder bed fusion additive manufacturing, and the results reveal that powder flow in the powder pile is critical for the formation and break of transient jamming.
