The effect of the particle shape and structure on the flowability of electrolytic copper powder. IV. The internal structure of the powder particles [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
The structure of powder particles was analysed by considering their cross sections. It was shown that the structure of powder particles of nonsieved flowing powders is sufficiently dense to produce a continuous surface, which does not allow the particles

Influence of the Pore Radius on the Penetration Depth of Inks in Binder Jetting—A Modification of the Washburn Equation

open access: yesJournal of Manufacturing and Materials Processing, 2022
In binder jetting (BJ), an ink is inserted layerwise into a powder bed to selectively bond the particles in the cross-section of a part. By predicting the penetration depth of the ink, the ideal layer thickness for BJ can be set.
