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 …

Additive manufacturing based on powder spreading is attracting great interest, but one key
weakness is that narrow gaps used for spreading produce non-uniformity in the spread layer …

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 …

In metal additive manufacturing (AM), powder bed fusion technologies such as selective
laser melting and binder jetting rely on the spreading of fine metal powder to build up the …

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 …

The effects of interstitial gas on the spreadability of Inconel 718 powder under conditions
relevant to powder-bed fusion additive manufacturing (PBF-AM) are investigated through …

Abstract The fine bimetallic Cu-Ni integrated nanoparticles were obtained by the modified
solution combustion synthesis in the air using glycine as a fuel. The synthesized …

Abstract Powder spreading in Additive Manufacturing (AM) has been analysed extensively
by the Discrete Element Method, but without considering the presence of ambient gas. For …

The dynamic behaviors of short fiber/polymer composite powders in powder paving process
of additive manufacturing are investigated by discrete element method simulations. Two …

The state of the art in property-process relationships in the laser polymer powder bed fusion
(LPPBF) subcategory of powder bed fusion (PBF) has derived relationships between the …
