Abstract

A three-dimensional printing system for manufacturing a three-dimensional article includes a build chamber, an overflow chamber adjacent to the build chamber, a motorized build plate, a powder coater including a vibration generator, a lateral movement mechanism coupled to the powder coater, and a controller. The controller is configured to perform a process to remove accumulated powder from surfaces of the powder coater according to the steps: (1) operate the lateral movement mechanism to position the powder coater over a location outside of the build chamber; (2) operate the vibration generator to shake the accumulated powder into the location outside of the build chamber. The location outside of the build chamber can be defined by the overflow chamber.
