Additive manufacturing devices and methods for the same are provided. The additive manufacturing device may include a stage configured to support a substrate, a printhead disposed above the stage, and a targeted heating system disposed proximal the printhead. The printhead may be configured to heat a build material to a molten build material and deposit the molten build material on the substrate in the form of droplets to fabricate the article. The targeted heating system may be configured to control a temperature or temperature gradient of the droplets in a flight path interposed between the printhead and the substrate.
