Laser‐Induced Keyhole Defect Dynamics during Metal Additive Manufacturing

The rendering in the background shows a metal component being manufactured through laser powder bed fusion additive manufacturing. The film strip contains frames from high-speed X-ray imaging revealing previously unseen void defect formation during the build which furthers the understanding of material properties and performance in these components. Further details can be found in the article number 1900455 by Johanna Nelson Weker and co-workers.
