Abstract Scope |
Advanced manufacturing (AM) has seen large growth following the advancement of technology. Physics-based approaches and predictions have become increasingly infeasible with computation because considerations are multi-faceted. Digital twin is a virtual representation of a part using in-situ monitoring, ex-situ characterization or other data sources. This data-driven digital twin (dd-DTs) approach has shown promise and success in integrated systems by feeding real-world, data-driven information into simulations. Having a digital twin of a part can offer certainty of a print's outcome before using materials using spatio-temproal graph neural network model, in which each track is a graph node, and each node as a feature vector. This approach allows for the production of more reliable AM parts and the ability to apply quality metrics in-situ for informed problem solving. This study focuses on dd-DT of laser powder bed fusion (L-PBF) and direct ink write (DIW) printed parts. |
