This review aims to build a coherent picture of the problem of powder spreading and
spreadability in metal Additive Manufacturing (AM) because of its impact on ensuring highly …

One of the most important aspects of Powder Bed Fusion (PBF) processes is the powder
layer spreading. The powder layer needs to be applied in such a way that its evenness and …

Powder spreading process is to use a spreader such as blade or roller to spread powder
layers for subsequent fusion in powder bed fusion additive manufacturing. In this work, the …

The dependence of powder flowability on particle cohesion can often be captured by a
dimensionless Bond number, however, whether the same is true for powder spreadability …

Identification of the most reliable method to characterise powder flow behaviour in
correlation with the conditions of powder spreading in additive manufacturing (AM) is still …

With the advantages of fast hardening, high early strength, excellent bonding strength and
room temperature curing, magnesium phosphate cement (MPC) is highly preferable for …

Particle properties play a key role in determining the flowability of cohesive fine powders
and consequently the quality of parts fabricated by additive manufacturing. However, how …

Powder bed fusion methods of additive manufacturing (AM) require consistent, reproducible,
and uniform layers of powder for the reliable production of high-quality parts, where …

Particle scale modelling of the process physics involved in laser powder bed fusion (LPBF)
is a recent research hotspot, and many efforts have been made in the literature. However, a …

Understanding powder spreading under low gravity conditions is essential for optimizing
final products using additive manufacturing in space. In this study, we investigated the role of …
