How do grains grow as the melt pool solidifies? Phase-field modeling traces nucleation, growth and coarsening layer-by-layer — each grain orientation a distinct color, turning invisible microstructure into quantitative data.

After layers stack up, how is residual stress distributed? A 3D color map shows the real distribution from blue (tension −130 MPa) to red (compression 3.2 GPa) — telling you exactly where warpage and cracking will appear.
