From: Real time observation of binder jetting printing process using high-speed X-ray imaging
(a) Image sequence showing behavior of two consecutive binder droplets. Both droplets show jetted droplet shape with spherical head and long, narrow tail. Three to four satellite droplets are observed near the end of the tail. Nominal velocity of the droplet head was around 8 m/s. The temporal separation between two consecutive frames is 50 μs. The size of the inset droplet figures is 120 μm by 740 μm. (b) Image sequence generated from different droplets showing the evolution in geometry of the droplet during flight. The head of the droplet becomes more spherical due to head pinch-off. The generation of satellites near the tails is clearly observed.
