Robotic directed energy deposition technology offers a robust, multi-faceted process for building and repairing large-scale components. EWI is currently involved in a broad research program to mature DED technology for use in the aerospace, energy, defense, shipbuilding, and heavy manufacturing industries. As part of this effort, EWI has installed a Cloos robotic DED system for...

In rapid response to the shortage of protective medical masks due to the COVID-19 pandemic, EWI has developed an easy-to-produce, compliant mask prototype. The Vacuum Formed Stop-gap Face Mask design was made available to the public and free via open source. Download the design, model, and specs at the NIH 3D Print Exchange. The mask...

Low force friction welding, a technology developed jointly by EWI and Manufacturing Technology, Inc. (MTI), combines resistance-based pre-heating with a translational relative motion to create a joint. The process has been successfully tested on metals and metal-based alloys. One such study is reviewed in Low Force Friction Welds in 4130 Steel: A Preliminary Microstructural Characterization,...
