Abstract
A method of manufacturing a three-dimensional article includes: (1) Loading a metal platen into a build chamber, the metal platen defines an upper surface; (2) Performing concurrent processes including operating a movement mechanism to vertically translate the platen, operating a laser system to impinge a radiation beam upon the upper surface of the platen, and receiving a signal from an acoustic sensor that is positioned within the build chamber; (3) Analyzing the signal including determining a height of optimal laser convergence for the platen; and (4) Based upon the analysis, adjusting the laser convergence height to a build plane height.
