Powder spreading in laser-powder bed fusion process

Granular Matter, 2021
Laser-Powder Bed Fusion (LPBF) has been extensively utilized by a broad range of manufacturing industries in recent years. Fabricating parts with high mechanical properties and smooth surfaces has motivated such industries and academic communities to study different aspects and steps of the LPBF process, including powder spreading, laser scanning, and ...

Melting modes in laser powder bed fusion

Materialia, 2019
Depending on processing conditions, laser powder bed fusion (LPBF) is known to have two operational regimes - conduction mode and keyhole mode. Heat conduction is the dominant heat transfer mechanism for conduction mode, whereas heat convection is the dominant heat transfer mechanism for keyhole mode.

Process monitoring of laser powder bed fusion

2021
The layerwise production paradigm entailed by the Laser Powder Bed Fusion process makes potentially available a large amount of information on a layer-by-layer basis, to determine the stability of the process and anticipate quality inspections of the part while it is being produced.

Characterization Of Ti6Al4V Powder For Laser Powder Bed Fusion

Euro PM2025 Proceedings
The performance of Laser Powder Bed Fusion (LPBF) is highly dependent on the quality of the metallic powder feedstock. This study characterizes a gas-atomized Ti6Al4V (Grade 5) powder, analyzing morphology, particle size distribution, flowability, true density, chemical composition, phase constitution, and thermal stability.

Advanced powder characterization for laser powder-bed fusion of AlSi10Mg

2018
Laser Powder-Bed Fusion is an additive manufacturing technique that allows to produce complex parts. Apart from process parameters, a key aspect of this system is powder quality, which strongly affects processability. In fact, a low powder quality, in terms of flowability, usually results in undesired phenomena, such as inadequate parts produced or ...
