![]() ![]() These results promote the characterisation of fluid dynamic phenomena during the laser powder-bed fusion (LPBF) process, which constitutes a key factor in the prevention of defects in additively manufactured parts. Numerical modelling was used to understand and quantify the observed flow behaviour, through the hydrodynamic treatment of the laser plume as a multi-component Ar-Fe plasma. Schlieren imaging enabled the visualisation of the Ar gas flow, which takes place in the atmosphere above the bed due to the plume, in addition to its interaction with affected particles. As the build progressed, denudation became less severe than for a single powder layer, but the occurrence of sintered and fused powder agglomerates, which were affected by the plume, increased. ![]() The inclination of the laser plume was shifted from forwards to backwards by changing power and scan speed, resulting in different denudation regimes with implications to the heat, mass and momentum transfer of the process. ![]() The formation of denuded areas where the powder was removed during single line and island scans over several layers were imaged for the first time. Plus, you don’t need to worry about unavailable video or audio files due to great support for all major file formats.In this work, we employ a combination of high-speed imaging and schlieren imaging, as well as multiphysics modelling, to elucidate the effects of the interaction between the laser beam and the powder bed. Plus, you can manage the entire library of photos, music, and videos on your PC.Īdditionally, this solution can support ISO files, ultra HD videos, and Dolby True HD audio with Hi-Res audio support for memorable audiovisual results in your own home. This ultimate media player software can bring you qualitative visual and audio performance for all your videos. Using this tool, you will enjoy flexible support for Blu-ray, 8K, and 4K video quality for your Windows device. If none of the solutions for troubleshooting Windows Media Player work, you could always consider using a different video player altogether, since the Windows Media Player is pretty limited in terms of functionality anyway.Ī great media player software that exceeds other competitors’ solutions is Cyberlink PowerDVD 21.
