This data was used to develop assess the validity of the transient heat equation with phase change and temperature-dependent coefficients as a model to predict the evolution of melt pools for rapid turnaround scan strategies in a laser powder bed fusion (PBF-LB) additive manufacturing (AM) process. The dataset contains the scan paths and parameters used to carry out a series of PBF-LB beam on plate experiments with top surface bright field images and tabulated measurements of the melt pool width and top surface area of the last track of each fabricated sample.", "distribution": [{"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-3662/Measurements.xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"}, {"downloadURL": "https://data.nist.gov/od/ds/ark:/88434/mds2-3662/Measurements.xlsx.sha256", "mediaType": "text/plain"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3662/Image%20Data.zip", "mediaType": "application/x-zip-compressed", "title": "Image Data"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3662/Measurements.xlsx", "mediaType": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "title": "Measurements"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3662/README.txt", "mediaType": "text/plain", "title": "README"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3662/Scan%20Strategy%20Data.zip", "mediaType": "application/x-zip-compressed", "title": "Scan Strategy Data"}], "identifier": "ark:/88434/mds2-3662", "issued": "2025-09-25", "keyword": ["Laser optimization", "Model validation", "Thermal simulation", "Turnaround effects"], "landingPage": "https://data.nist.gov/od/id/mds2-3662", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2025-06-26 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "references": ["https://doi.org/10.1007/s40964-025-01147-9"], "theme": ["Manufacturing:Additive manufacturing", "Manufacturing:Process improvement", "Manufacturing:Process measurement and control", "Manufacturing:Quality assurance", "Materials:Metals", "Materials:Modeling and computational material science", "Mathematics and Statistics:Experiment design", "Mathematics and Statistics:Numerical methods and software", "Metrology:Dimensional metrology"], "title": "Dataset for Model Validation of Transient Melt Pool Dynamics in Laser Powder Bed Fusion of Nickel Super Alloy 625: Top Surface Melt Pool Width and Area Measurements from Beam on Plate Experiments"}
