In some examples, a controller receives measurement data responsive to operation of a vibrated spreader for use in dispensing a build material onto a target surface, and controls a frequency of a vibration of the spreader based on the measurement data.

Frequency control of spreader vibrations

In example implementations, a spreading blade is provided. The spreading blade includes a body portion, an ultrasonic vibration source, and a kicker. The ultrasonic vibration source is coupled to a top portion of the body portion to apply a vibration along a cross-sectional length of the body portion. The kicker is coupled to a side facing a process direction at a bottom end of the body portion. The kicker comprises a tip formed by a combination of two angled surfaces that extend from a lateral side of the body portion.
