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 ...

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.

Comparison the Preparation Methods of Powder Feedstock for Laser Powder Bed Fusion

Solid State Phenomena, 2022
Four various methods of powder feedstock preparation for laser powder bed fusion are compared. Application of commercial spherical powder leads to the formation of single-phased state. Powder mechanically alloyed during 14 minutes in air atmosphere provides conditions for the formation of double-phased state with nonuniform distribution of components ...
