Paper No: MSEC2022-85513
... Abstract Due to inherent drawbacks of metal 3D printing process such poor dimensional accuracy, surface quality, and various defects, a process monitoring system with an appropriate information visualization interface has been required. In the recent technological mega-trend, the 4th industrial...

... as a function of gas flow speed and direction. It was found that a mean gas flow velocity of 6.7 m/s from a nozzle 6.35 mm in diameter was sufficient to reduce meltpool aspect ratio CV to less than 15 %. Real-time inline hotspot area and its CV were evaluated as a process monitoring signature for identifying...
