Abstract
A manufacturing system for fabricating a three-dimensional article includes a housing, a sensor within the housing, a coater, a removable powder module (RPM) with a platen, a laser system, and a controller. A method of operating the manufacturing system includes installing the RPM into the housing, forming pillars onto the platen, positioning the top surfaces of the pillars a distance D below a build plane, installing a calibration plate onto the top surfaces of the pillars, and then calibrating the laser system using the sensor. The sensor can include one or more of an optical sensor and an acoustic sensor.
