Abstract: In one example, a processor readable medium having instructions thereon that when executed cause an additive manufacturing machine to vary operating characteristics of a fusing laser beam at multiple different voxel locations in a layer of build material according to an energy dosage to be applied at each voxel location in an object slice, including multiple different energy dosages for corresponding multiple different voxel locations in the slice.
