Abstract
A method of calibrating a laser of an additive manufacturing system involves processing a test pattern with the laser while varying one or more of laser power and/or scan speed. Thermal energy emitted from the resulting meltpool is measured while processing the test pattern. The power of the laser is calculated using a relationship between volumetric energy density and the thermal emissions, and the laser power is adjusted based on the calculated laser power. An additive manufacturing system for performing such a method may include a laser, a thermal sensor configured to measure meltpool thermal emissions, a processor configured to calculate a laser power based on the measured meltpool thermal emissions of the test pattern, and a controller configured to adjust the laser power based on the calculated laser power.
