Abstract

A powder bed sensing system and method is provided. A defect detection eddy current sensor array is configured to be movably coupled with respect to a powder bed, and generate a first plurality of sensor signals while moving over a workpiece in the powder bed. A workpiece edge detection eddy current sensor array is configured to be movably coupled with respect to the powder bed, and generates a second plurality of sensor signals while moving over the workpiece in the powder bed. A controller is coupled to the defect detection eddy current sensor array and the workpiece edge detection eddy current sensor array. The controller initiates an action based on at least one of a workpiece material layer quality and a workpiece edge location quality determined based on the first plurality of sensor signals and the second plurality of sensor signals.
