Abstract: A method of generating a spatial map of sensor data collected during additive manufacturing, in which a plurality of layers of powder are selectively melted with an energy beam to form an object. The method includes receiving sensor data collected during additive manufacturing of an object, the sensor data including sensor values, the sensor values captured for different coordinate locations of the energy beam during the additive manufacturing of the object, and generating cell values for a corresponding cell-based spatial mapping of the sensor data. Each of the cell values is determined from a respective plurality of the sensor values extending over an area/volume comparable to an extent of the melt pool or the energy beam spot.

Abstract: A method of monitoring an additive manufacturing process, in which an object is built in a layer-by-layer manner by directing a laser beam using at least one movable guiding element of a scanner to solidify selected regions of a material bed. The method includes recording position values generated from a transducer measuring positions of the at least one movable guiding element, recording sensor values generated from a sensor for detecting radiation emitted from the material bed and transmitted to the sensor by the movable guiding element of the scanner, and associating each sensor value with a corresponding one of the position values.
