  This video shows the
spreading of relatively coarse reused stainless steel (17-4 PH) powder
feedstock (D50=38.4 μm) for laser powder bed fusion (LPBF) using the
powder spreading testbed at 60 mm/s recoater velocity. Additionally, the
recoater blade is ceramic, the layer height has been set to 40 μm and this
spread is conducted over previously spread powder (multi-layer spreading) as it
occurs in LPBF equipment. The frame rate of the video is 16000 frames per
second (fps), and the resolution of each frame is 1000 pixels by 860 pixels.
The playback speed is 30 fps, so it plays 533 times slower than the actual
spreading.
