Abstract
A three-dimensional (“3D”) printing system for printing on a substrate, the printing system including a powder distribution device dispensing powder on the substrate and including a blade-shaped end, the blade-shaped end disposed at a height above the substrate; a powder uniformization device located at a distance from the powder distribution device along a direction substantially parallel to a longitudinal axis of the substrate; one or more sensors disposed upstream from the powder uniformization device and configured to determine one or more parameters of a thickness of the dispensed powder at one or more locations; and a control apparatus configured to determine whether the one or more parameters of the thickness is above a predetermined threshold value, and if the one or more parameters is determined to be above the predetermined threshold value, to adjust the powder distribution device.
