Extending powder lifetime in additive manufacturing: Chemical etching of stainless steel spatter
In laser powder bed fusion, unconsolidated metal powder on the build plate tends to comprise a proportion of oxidised powder after repeated use. This is generally caused by the generation of oxidised spatter particles during processing which can ...

COOLING RATES OF SPATTER DEPOSITS: A TWO-DIMENSIONAL THERMAL DIFFUSION MODEL AND ITS IMPLICATIONS FOR SPATTER PILE STABILITY [PDF]
Spatter occurs when erupted lava is hot enough to deform and agglutinate (adhere to other erupted clasts). Spatter deposits will agglutinate at high temperatures; however, if the temperature is too high it will re-mobilize and flow as lava.

CFD–DPM Simulation Study of the Effect of Powder Layer Thickness on the SLM Spatter Behavior
Selective Laser Melting (SLM) has significant advantages in manufacturing complex structural components and refining the alloy microstructure; however, spatter, as a phenomenon that accompanies the entire SLM forming process, is prone to problems such as

Background. Spatter formation at melt pool swellings at the keyhole rear wall is a major issue for laser deep penetration welding at speeds beyond 8 m/min. A gas nozzle directed towards the keyhole, that supplies shielding gas locally, is advantageous in

3D tracking velocimetry of L-PBF spatter particles using a single high-speed plenoptic camera
Particle spatter is an unavoidable by-product of the Laser-Powder Bed Fusion (L-PBF) process, as the high intensity of the incoming laser beam generates high vapor fluxes on the meltpool, allowing metal particles to be ejected into the process ...

Preventing Evaporation Products for High-Quality Metal Film in Directed Energy Deposition: A Review
Directed energy deposition (DED), a type of additive manufacturing (AM) is a process that enables high-speed deposition using laser technology. The application of DED extends not only to 3D printing, but also to the 2D surface modification by direct ...
