Multi-Label Phase Diagram Prediction in Complex Alloys via Physics-Informed Graph Attention Networks
Eunjeong Park, Amrita Basak
Accurate phase equilibria are foundational to alloy design because they encode the underlying thermodynamics governing stability, transformations, and processing windows. However,…
Robust Linear Quadratic Optimal Control of Cementitious Material Extrusion
Mandana Mohammadi Looey, Amrita Basak, Satadru Dey
Extrusion-based 3D printing of cementitious materials enables fabrication of complex structures, however it is highly sensitive to disturbances, material property variations, and p…
Real-Time Regulation of Direct Ink Writing Using Model Reference Adaptive Control
Mandana Mohammadi Looey, Amrita Basak, Satadru Dey
Direct Ink Writing (DIW) has gained attention for its potential to reduce printing time and material waste. However, maintaining precise geometry and consistent print quality remai…
Enhanced geometry prediction in laser directed energy deposition using meta-learning
Abdul Malik Al Mardhouf Al Saadi, Amrita Basak
Accurate bead geometry prediction in laser-directed energy deposition (L-DED) is often hindered by the scarcity and heterogeneity of experimental datasets collected under different…
Physics-Informed Dynamical Modeling of Extrusion-Based 3D Printing Processes
Mandana Mohammadi Looey, Marissa Loraine Scalise, Amrita Basak +1
The trade-off between model fidelity and computational cost remains a central challenge in the computational modeling of extrusion-based 3D printing, particularly for real time opt…
Real-Time Thermal State Estimation and Forecasting in Laser Powder Bed Fusion
Yukta Pareek, Abdul Malik Al Mardhouf Al Saadi, Amrita Basak +1
