Abstract

Methods of reproducibly determining a beam size parameter of a laser beam utilizing a calibration standard and additive manufacturing systems that perform the methods. The calibration standard includes a calibration body that includes an aperture and defines a plurality of distinct aperture dimensions. Each distinct aperture dimension is measured along a corresponding dimension vector. The method includes, for each distinct aperture dimension, scanning the laser beam across the calibration body and along the corresponding dimension vector and, during the scanning, measuring a resultant energy of the laser beam as a function of position along the corresponding dimension vector. The method also includes generating an energy-dimension correlation between a characteristic of the resultant energy of the laser beam for each distinct aperture dimension and the distinct aperture dimension. The method further includes determining the beam size parameter based, at least in part, on the energy-dimension correlation.
