Additive Manufacturing (Page 6)

By Henry Cialone President & CEO, EWI Innovation can be really challenging but it’s also a lot of fun, as seen with our latest endeavor: a fully 3D-printed model submarine. The sub offers a dynamic demonstration of several of EWI’s additive manufacturing (AM) processes. The sheer size and unique features of the submarine not only...

In metal additive manufacturing (AM), grain size variations within the material microstructure can have a significant impact on its mechanical properties, thus affecting the integrity of the part. Being able to accurately measure grain size distribution throughout the build can be used to improve part strength and fatigue life. EWI has developed a grain size...

Common aerospace materials such as high-nickel alloys (such as René 80) or high-strength aluminum alloys (6000 and 7000 series) are not currently manufactured using additive manufacturing (AM) due to hot cracking.  As part of a $5M Department of Energy program, EWI, GE Research, and the University of South Carolina developed a model to predict and...
