Abstract
A method of depositing powder in an additive manufacturing system includes driving a recoater along a drive axis and oscillating the recoater along an oscillation axis. The recoater is oscillated while the recoater is driven along the drive axis to overcome the effect of one or more particle movement restriction mechanisms for smoothing powder deposited in a build chamber of an additive manufacturing system.

A method of depositing powder in an additive manufacturing system, comprising:
- driving a recoater along a drive axis;
- oscillating the recoater along an oscillation axis while driving the recoater along the drive axis to overcome an effect of one or more particle movement restriction mechanisms and smooth the powder in a build chamber of an additive manufacturing system;
- and
- pitching the recoater at pitch angle relative to the drive axis and yawing the recoater at a yaw angle relative to the drive axis.
