Abstract
A method of monitoring an additive manufacturing process in which a layer of powdered material is deposited in a recoating process so as to define a build surface, and a directed energy source is used to create a weld pool in the build surface and selectively fuse the powdered material to form a workpiece. The method includes: measuring a vibration signal profile generated by the recoating process; and controlling at least one aspect of the additive manufacturing process in response to the measured vibration signal profile.
