UAM 3D Printing Service: Multi-Material Superalloy Parts Without Melting
Introduction
Ultrasonic Additive Manufacturing (UAM) is a groundbreaking solid-state 3D printing technology, capable of producing multi-material superalloy parts without melting. Leveraging ultrasonic vibrations to create metallurgical bonds at temperatures below 150°C, UAM effectively combines superalloys such as Inconel 718, Titanium Alloys, and even copper, delivering superior bond strength, low residual stress, and exceptional mechanical integrity.
Compared to traditional fusion-based methods, UAM reduces thermal distortion by up to 90%, enabling precise integration of electronics, fibers, and sensors directly into metal structures, significantly enhancing performance and functionality.
