Fabrisonic’s SonicLayer 7200 printing aluminum foils and then transitioning to copper foils. the entire thickness of the part is 100% metallurgically bonded, yet the low temperature developed during ultrasonic welding does not create brittle phases at the interface.  As shown, the metal being printed can be changed layer by layer throughout the manufacturing process.  This enables UAM to print complex metallic gradients as well as simple transition joints.
