AM Bench 2025 Measurement Results Data: Optical Microscopy of arrays of adjacent laser tracks (pads) on alloy 718 plate

The dataset is melt pool cross-sectional microscopy and measurements for 2D arrays of laser tracks on solid metal IN718 plates and single layers of IN718 powder on solid metal IN718 plates. The primary laser parameters such as laser power, speed, and spot diameter, and hatch spacing were fixed. The pad geometry, laser turnaround time (i.e., skywriting time), and powder layer thickness were the investigated variables. The experiments were part of AM Bench 2025 (AMB2025-06 and AMB2025-07 benchmarks). See https://www.nist.gov/ambench/am-bench-2025-measurements-and-challenge-problems
