Abstract
A powder bed additive manufacturing apparatus includes a build sleeve, a build platform for supporting a powder bed and object during a build, the build platform lowerable in the build sleeve, and at least one acoustic sensing system. The acoustic sensing system includes an acoustic emission sensor and an acoustic waveguide. The acoustic waveguide extends through the build platform such that a receiving end of the acoustic waveguide distal from the acoustic emission sensor abuts a surface of a build substrate removable mounted to the build platform to transmit structure-borne acoustic waves from the build substrate to the acoustic emission sensor.
