Selective laser melting fabricated tungsten with thin-walled structure: role of linear energy density on temperature evolution and manufacturing quality

Formation and extreme thickness controlling mechanism of ultra-thin-wall tungsten grids fabricated via selective laser melting

“…Ma et al [10] investigated a copper flange with a slender wall thickness measuring 200 m. Previous researchers [11][12][13] employed finite element and experimental optimization of process parameters to fabricate tungsten grids with a wall thickness around or above 130 m using multiple tracks on a single wall. However, for CT equipment applications, ASGs with a wall thickness below 100 m are required.…”
