1. An additive manufacturing system, the system comprising:
a print tool comprising a tungsten carbide bar having a thickness of between 2-3 mm and a length of between 12-25 mm;
an ultrasonic energy source; . . . the voxel location; and
control a microstructure of the formed object by adjusting a magnitude of the ultrasonic energy that is input via the ultrasonic energy source during the printing step, wherein responsive to the supply of the ultrasonic energy through the print tool by the vibrating the print tool, a portion of the print tool in contact with the metal filament vibrates with an amplitude of between 0.2 microns and 3.5 microns.
