Additive Manufacturing (Page 4)

Interested in using directed energy deposition (DED) in your operation to build fine component features or execute repairs? Laser DED can be quite expensive. However, EWI has recently developed a DED process based on gas metal arc welding (GMAW) that is significantly more cost efficient. The project is described in Reciprocating Wire Feed Gas Metal...

This past September, EWI was awarded a $17 million, 3-year contract with the U.S. Air Force to develop convergent manufacturing (CM) platforms for maintenance, repair, and overhaul (MRO) sustainment. The project is now being managed under the auspices of the Air Force Research Laboratory (AFRL). Technical development work is already taking place at EWI’s labs...

Magnetic materials are essential to electric propulsion systems.  Key attributes of these materials include resistivity and grain size. Refining grain size increases magnetic saturation limits, and thus allows for lighter, more compact motor designs. Using powder-based processing is one way to achieve fine grain size, but the main methods for doing so are energy intensive,...
