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 …

Independent from their intended purpose, the understanding of structural characteristics of
random packings of particles having defined shapes is important to understand and optimize …

Laser powder bed fusion (LPBF) additive manufacturing technology is sensitive to variations
in powder particle morphology and size distribution. However, the absence of a clear link …

Powder spreading is a crucial step in the powder bed fusion process, which controls the
quality of powder bed and consequently affects the quality of printed parts. To date …

This work investigates the effects of powder characteristics, particularly particle size
distribution (PSD), on the micro-/defect-structure, tensile, and fatigue properties of Grade 23 …

A simplified analytical model of the laser powder bed fusion (LPBF) process was used to
develop a novel density prediction approach that can be adapted for any given powder …

The quality and uniformity of the powder layer have a direct impact on the performance of
parts produced via powder bed fusion (PBF). Because powder layer properties depend on …

In binder jetting additive manufacturing, the final part density is closely related to powder
bed density and green density. Though powder bed density is considered one of the most …

In the dynamic landscape of advanced manufacturing, the confluence of laser powder bed
fusion (LPBF) and machine learning (ML) has recently garnered significant attention in many …

Understanding and controlling particle segregation during spreading are critical in
improving the quality of the powder bed and the performance of final products in selective …
