Abstract

Systems, methods and computer program products are disclosed that facilitate measuring the light output of an additive manufacturing device light source without utilizing additional equipment, such as a light meter. Once the light source output has been measured, such information can be utilized for a variety of purposes, including, but not limited to: (i) delivering a uniform amount of light energy over time to each portion of a layer being formed; (ii) adjusting the intensity of each controllable element (e.g., pixel) of the light source to the measured minimum, thereby creating a uniformly intense light source; and (iii) minimizing the build time of layers or portions of a layer being formed based on the maximum intensity available within a given area of the build area.
