Resistance-based sintering is a highly effective method for consolidating metal powders that combines the use of axial pressure with a flowing, high-intensity current without the need for atmospheric chambers. EWI began developing this technique a couple of years ago in an effort to replace spark plasma sintering. Our team made use of its considerable resistance...

For certain manufacturing applications, making selected components out of plastic via 3D printing has great advantages. A significant disadvantage for high-volume production, however, is the slow extrusion rates of polymer materials. EWI has developed a new technique using ultrasonic power that can increase the speed of polymer extrusion. This method is discussed in Speeding Up...

The Additive Manufacturing Consortium (AMC), operated by EWI, is pleased to announce its 2023 research portfolio, which includes three new projects and two continuations: High-strength Aluminum Testing and Characterization of Commercially Available Materials (new) – This project will conduct builds and compare results from three commercially available materials in the 7XXX series family. Materials from...
