| Abstract Scope |
A digital twin (DT) is an amalgam of physics-based and/or data driven models that describe a physical system. In additive manufacturing (AM), inputs/outputs of digital and physical twins are identical. Like many, LLNL’s approach requires refining DTs with data to better capture behavior of its physical twin via advanced analytical techniques. As such, a DT’s evolving parameter set can inform of machine health and aging behavior, providing actionable insights on lifetime performance. A suite of DTs that capture all fabrication and inspection platforms of a given AM process can accelerate production for qualifying parts at scale with minimized and quantified defects. This talk will walk through examples of how we are leveraging data from integrated pairs of real and digital twins of inspection and fabrication platforms to become more flexible and agile.
