Abstract: An additive manufacturing system includes a particulate delivery system including at least one dispenser configured to dispense a plurality of first particulates and a plurality of second particulates onto a surface. The particulate delivery system includes a first particulate supply and a second particulate supply coupled to the at least one dispenser. The at least one dispenser is configured to deposit the plurality of first particulates and the plurality of second particulates adjacent each other. At least a portion of at least one of the plurality of first particulates and the plurality of second particulates is fused.

Abstract: A method for fabricating a component of with an additive manufacturing system include entraining a first portion of first material particles in an airflow generated by a vacuum source and engaging the first portion of the first material particles against an air permeable screen. The first portion of the first material particles is deposited onto a build platform. The method also includes entraining a second portion of second material particles in the airflow and engaging the second portion of the second material particles against the air permeable screen. The second portion of the second material particles is deposited onto the build platform. An energy source transfers heat to at least a portion of at least one of the first portion of the first material particles or the second portion of the second material particles to facilitate consolidating material particles to fabricate the component.
