Abstract: Systems of weldable wires, powder, and materials comprising an aluminum-magnesium-scandium alloy, and methods for additive manufacturing the alloy are described. The alloy can be utilized in additive manufacturing to additively manufacture at industrial scales. With post treatment, the additive manufactured alloys can have advantageous properties for aerospace applications.

Abstract: A system and method are disclosed for cold working an additively manufactured component including a platform, a deposition robot, and a roller assembly. The platform is configured to support a three-dimensional object. The deposition robot is configured to deposit successive material layers that, after deposition, form the three-dimensional object. The deposition robot includes an arm having a deposition end and a deposition head coupled to the deposition end of the arm. The deposition head is configured to deposit a new material later of the successive material layers. The roller assembly is disposed around the new material layer and configured to compress a lateral thickness of the new material layer after the new material layer has been deposited by the deposition robot.
