Slope surface flow speed. (a,b) Slope surface flow speed versus time for each tracked particle (a) and average surface flow speed (b) for 316 L stainless steel powder with average diameter of 67 µm. (c,d) Slope surface flow speed versus time for each tracked particle (c) and average surface flow speed (d) for 316 L stainless steel powder with an average diameter of 23 µm. Eight particles on the surface of the powder slope were tracked for each powder size. The 316 L stainless steel powder with an average diameter of 67 µm presented an average slope surface flow speed of 77 mm/s with a standard deviation of 7 mm/s. The 316 L stainless steel powder with an average diameter of 23 µm presented an average slope surface flow speed of 50 mm/s with a standard deviation of 14 mm/s.
