ABSTRACT:
An apparatus and a method of using the apparatus wherein a radiation emitter is positioned adjacent a sensor apparatus within a process chamber in a laser sinter system that emits radiation to the sensor apparatus and a calibration apparatus receives readings from the sensor apparatus to compare temperature sensings received from the sensor apparatus with set emission signals from the radiation emitter to adjust the temperature sensings to calibrate the sensor apparatus during the forming of a three-dimensional article. The calibration is done repeatedly during the build process of the three-dimensional article.
