Researchers at Oak Ridge National Laboratory (ORNL) have found a way to control the structure and properties of metal components during an additive manufacturing process with a heretofore unmatched precision seen by conventional manufacturing methods.
“We’re using well established metallurgical phenomena, but we’ve never been able to control the processes well enough to take advantage of them at this scale and at this level of detail,” said Suresh Babu, the University of Tennessee-ORNL Governor’s Chair for Advanced Manufacturing.
