A large-scale GPU-accelerated DEM–ray-tracing method for particle-resolved thermo-optical-mechanical simulation of selective laser sintering of polymer powders

Selective laser sintering (SLS) involves strongly coupled laser transport, particle-scale heat transfer, particle motion, and sintering, making high-fidelity simulation of realistic powder beds computationally demanding. This work presents a large-scale GPU-accelerated DEM–ray-tr...
