Abstract
A control system for use in an additive manufacturing system. A recoating device is configured to distribute powder for forming a component and a recoating motor is configured to move at least one of the powder bed and the recoating device relative to each other. The control system includes at least one vibration sensor configured to collect vibration data, a torque sensor coupled to the recoating motor and configured to collect the torque output data, and an optical sensor configured to collect reflected light data. The control system includes a controller configured to receive the vibration data, receive the torque output data, and receive the reflected light data, the controller further configured to determine at least one powder bed characteristic based on at least one of the data, and control at least one recoating parameter of the recoating device based on the at least one determined powder bed characteristic.
