LPBF Digital Twin

Draw a laser path → 3D U-Net propagator predicts the temperature field (plan view, depth section, and error vs. the classical solver)
① Draw laser path (build plate, mm)
16.0 W 120 µm 0.35 m/s 80 steps 0.0 mm
Solver
② Surface temperature (plan view) 293 K — K
③ Depth cross-section (x–z at y = 0.0 mm) — surface on top
④ Error vs classical FV/BE solver (surrogate − truth) — —

Enable “compare vs classical solver” and re-run to see the error field.
