3D tracking velocimetry of L-PBF spatter particles using a single high-speed plenoptic camera
Additive Manufacturing Letters, 2022 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 ...

Influence of Magnesium on Spatter Behavior in Laser Deep Penetration Welding of Aluminum Alloys
Journal of Manufacturing and Materials Processing, 2019 The quality of welds, as well as the necessity of post-processing, is challenged by spatter generation during the laser keyhole welding process. In this study, the influence of the magnesium content on spatter behavior is studied for three aluminum ...

Pure titanium fabrication with spatter-less selective laser melting in vacuum
Results in Optics, 2021 Selective laser melting (SLM), which is an additive manufacturing technology, is attractive due to its ability to freely form shapes. SLM forms a 3D material by building it layer-by-layer from a metal powder. However, some issues have yet to be resolved,

Simple monitoring of welding spatter for quantification and observation using a mobile phone
Advances in Mechanical Engineering, 2017 Unstable welding arcs can cause the scattering of molten welding pools, a phenomenon known as welding spatter. Spatter deteriorates product quality and necessitates inefficient secondary processes and their associated costs for its removal.
