Electron Beams Magically Heal Microscopic Fractures, May Also Enable Creation of Objects One Atom at a Time - The Debrief
Electron beams that power microscopes have shown the seemingly magical ability to heal microscopic fractures atom by atom.

Creating microstructures. Makes me wonder if they can 3D print an object using atomic particles? A nano 3D printer?
“The researchers showed that the electron beams could be used constructively to engineer novel nanostructures atom-by-atom.”
