Abstract: Systems and methods are provided for producing powders. The system includes a housing having an enclosure, a crucible configured to produce a melt of a first material, a droplet device configured to receive the melt of the first material from the crucible and produce a flow of droplets of the melt of the first material within the enclosure of the housing, wherein the droplets solidify within the enclosure, and a distribution device configured to propel a second material into the flow of droplets of the first material within the enclosure such that the second material is mixed with the droplets of the first material to produce the powder that includes the first material, the second material, and/or a reaction product thereof.

Abstract: An additive manufacturing method comprises: positioning a sheet of composite material; curing a predetermined portion of the sheet; cutting the sheet about the perimeter of the predetermined portion to create a preceding processed sheet; adding a successive sheet of composite material atop and in contact with the preceding processed sheet; curing a predetermined portion of the successive sheet such that the predetermined portions of the successive sheet and the preceding processed sheet are bonded together; and cutting the successive sheet about the perimeter of its predetermined portion to create a subsequent processed sheet. The steps of adding, curing and cutting a successive sheet may be repeated for a plurality of cycles to produce a three-dimensional composite product.
