Schematic diagram of the 3DP process. (a) The roller spreads one layer of powder from the feed area to the build area; (b) print head selectively injects binder droplet on the powder bed; (c) after printing a layer, the roller returns to the feed area; (d) powder in the feed area is raised while that in the build area is lowered. The roller then spreads another layer of powder.
