KIAT–CORIA G.R.I.D Webinar Highlights Digital Twin Simulation for Composite Additive Manufacturing
One April 23, 2026, The KIAT–CORIA G.R.I.D Webinar Series featured a presentation by Professor Garam Kim of Purdue University, titled “Physics Based Digital Twin Simulation Driven Fiber-Reinforced Composites Additive Manufacturing for Tooling Application.” The event brought together a diverse international audience from academia, research institutes, and industry.
Professor Garam Kim introduced Large-Scale Additive Manufacturing (LSAM), a form of Extrusion Deposition Additive Manufacturing (EDAM) using fiber-reinforced thermoplastics to achieve deposition rates of up to 220 kg/hr for rapid fabrication of multi-meter tooling. He also addressed challenges from anisotropic material behavior and non-isothermal processing that lead to deformation and delamination.
A physics-based virtual twin, ADDITIVE3D, was presented to predict residual stresses, deformation, interlayer bonding, and delamination, while evaluating as-printed performance. The approach emphasizes predicting and compensating for shape changes during printing, machining, and high-temperature operation up to 180°C.
This seminar was co-organized by Professor Martin Byung-Guk Jun, Director of CORIA, and Hwan Il Yoo, Chief representative of KIAT U.S. office. The KIAT-CORIA Webinar series connects Purdue professors with Korean academics, industry researchers, and institutions to foster joint research and networking. The seminars provide a platform for collaboration, knowledge sharing, and building partnerships to drive future technological innovation.
