Additive Manufacturing (Page 7)

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...

Additive manufacturing (AM) continues to grow in popularity as manufacturing firms develop better understanding of how to extract value from the expensive process. Designers and engineers continue to add complexity into components to tip the cost/value balance in favor of AM, as well as to gain additional benefits from light weighting, reduced assembly efforts, better...
