Low Temperature Metal Additive Manufacturing for Heat Exchangers

Over the last few years, 3D printing has promised designers freedom of geometry. Solid state (no melting) 3D printing processes are now allowing freedom of material. New processes leverage ultrasonic energy to produce metallurgical bonds between layers of metal foils near room temperature. This low temperature attribute of the process enables printing multiple metals in one part, creating complex internal channels, and embedding electronics into solid metal. These attributes have been leveraged to create millions of electrification components in the automotive space – both electrical busbars and complex heat exchangers.
