SynAM-E: Simulated Event-Camera Benchmark for Melt-Pool Monitoring in Metal Additive Manufacturing

SynAM-E is an 85-shard simulated event-camera corpus for cross-institution melt-pool monitoring in metal additive manufacturing. It is derived from 15 published high-speed video sources at 8 institutions via calibrated v2e simulation (3,923,454,180 events after 2-px guard-band filtering). Each shard ships events.h5 plus a manifest with full provenance.
