SPH Simulated LPBF Melt Pool Dataset Single track laser powder bed fusion (LPBF) melt pool simulations for Ti 6Al 4V, produced with the LAMAS smoothed particle hydrodynamics solver. 241 simulations sampled uniformly i.i.d. over a 4D process parameter cube (laser power, scan speed, laser spot radius, substrate temperature), spanning conduction, transition, and keyhole regimes. Companion to the NeurIPS 2026 Evaluations & Datasets Track submission A Simulation Based Dataset for Melt Pool Dynamics in Single Track Laser Powder Bed Fusion . See examples folder in order to reproduce the results of the toy models. Maintained by Ioan Daniel Crăciun, Chair for Physics Enhanced Machine Learning, Technical University of Munich.
