Mark Norfolk PE, President & CEO, Fabrisonic
Ultrasonic Additive Manufacturing (UAM) is a 3D metal printing technology which does not utilizes melting for part formation. Instead, ultrasonic scrubbing energy is used to join the metals together near room temperature without a controlled atmosphere. These attributes allow creation of large metal parts to be produced with aluminum alloys, dissimilar metals, and internal passageways for heat transfer devices. Recently, Fabrisonic has been developing next generation heat exchanger devices for the Jet Propulsion Lab at the National Aeronautics and Space Administration in collaboration with Sheridan Solutions, LLC. These devices demonstrate as-built burst pressures upward of 2000 psi (130 bar), leak rates near 1e-9 cc/s, and channel widths near 0.375 in (9.5 mm). The use of a low melting point solder as a support material and hot isostatic pressing can be used to enhance performance even further.
