Abstract

Systems and methods for generating an energy density map of an object to be built in an additive manufacturing environment are provided. Certain embodiments provide a method for building an object utilizing additive manufacturing, the method including: receiving a job file for building the object, wherein the job file includes a plurality of slices of the object, and wherein a first slice of the object indicates scanning lines for applying an energy source to build material to build the first slice of the object; determining operation parameters of the energy source; and generating a first energy density map of the first slice of the object based on the job file and the operation parameters of the energy source, wherein the first energy density map indicates an amount of energy from the energy source per area of build material applied to the build material for the first slice of the object.
