  • MULTIMATERIAL POWDER BED PATTERNING FOR ADDITIVE MANUFACTURING METHOD
    Publication number: 20230302727
    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.
    Type: Application

  • Multimaterial powder bed patterning for additive manufacturing method
    Patent number: 11697246
    Abstract: The present disclosure relates to an additive manufacturing system. In one embodiment the system makes use of a reservoir for holding a granular material feedstock. A nozzle is in communication with the reservoir for releasing the granular material feedstock in a controlled fashion from the reservoir to form at least one layer of a part. An excitation source is included for applying a signal 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.
