AI provides real-time quality assessment for powder bed fusion 3D printing

Researchers at Oak Ridge National Laboratory (TN, USA) have developed an AI-based program to monitor the quality of objects 3D-printed by powder bed fusion 3D printers, in real-time. Named ‘Peregrine’ and described in Additive Manufacturing, the team claims the software supports the advanced manufacturing ‘digital thread’ currently in development, based on the collection and analysis of data throughout different stages of the manufacturing process. “Capturing that information creates a digital ‘clone’ for each part, providing a trove of data from the raw material to the operational component,” explained Vincent Paquit, lead of advanced manufacturing data analytics research. “We then use...
