1. An additive manufacturing device for fabricating an article, comprising:
a stage configured to support a substrate;
a printhead disposed above the stage, the printhead configured to heat a build material to a molten build material and deposit the molten build material on the substrate as droplets to fabricate the article; and
a targeted heating system disposed proximal the printhead, the targeted heating system configured to control a temperature or temperature gradient of the droplets deposited on the substrate, an area proximal the substrate, or combinations thereof,
wherein the targeted heating system comprises a monogon system, the monogon system comprising one or more monogon scanners, one or more Galvo mirrors, or combinations thereof.
