a A X-ray image showing the melt pool. See the video in Supplementary Movie 2. b 3D view schematic showing the melt pool flow. c Side view and (d) corresponding 2D projected streamlines by modelling. e front view and (f) corresponding 2D projected streamlines by modelling. T in (c–f) represents temperature in K. The traverse speed is 2 mm s−1, and the laser power is 160 W. Scale bars in (a) and (c–f) are 300 μm.
