Abstract
The present disclosure relates to a method for additively manufacturing a part. The method may involve using a reservoir to hold a granular material feedstock, and using a nozzle in communication with the reservoir to release the granular material feedstock in a controlled fashion from the reservoir to form at least one layer of a part. The method may further involve using an excitation source for applying a signal to the nozzle which induces a controlled release of the granular material feedstock from the nozzle as needed to pattern the granular material feedstock as necessary to form a layer of the part.
