Datasets

Datasets

These datasets are provided for public, open use to enable broader development of data processing or analyses.  NIST does not endorse or support conclusions made by outside organizations based on their analyses or use of these datasets but encourage researchers to contact the respective dataset authors with questions or collaboration.

Measurement tools, analyses, or data formats may change from dataset to dataset as methods improve, therefor it is not recommended to assume the conditions of one dataset apply to the other.  If using this data, please cite the data DOI from the NIST Publica Data Repository (PDR) given on each dataset’s PDR landing page.  Please also cite the associated data description articles in the Journal of Research NIST, if available. 

The following open source utilities are recommended for file viewing:

  • Decompression of large *.zip files should use the free utility 7-zip
  • Audio-video interleave (AVI) files viewed with the free utility VirtualDub.
  • Some AVI files may be compressed using the Lagarith Lossless Codec.
  • Image files and TIFF stacks may be viewed using ImageJ or Fiji.
  • HDF5 file structure and metadata may be viewed using HDFView.

Process monitoring datasets are provided listed below in chronological order and provide additional improvements with each new dataset.  However, it is recommended that users review description articles and literature for earlier datasets.

Process Monitoring Datasets

“Three-Dimensional Scan Strategies” – Process Monitoring Data

Laser scan speed represented by colorbar, mapped to XY locations within each part every 20 layers.

“Overhang Part X4” – Process Monitoring Data

  • Data description: https://doi.org/10.6028/jres.125.027  
  • Data DOI and download: https://doi.org/10.18434/M32233  
  • Summary: Four nominally identical IN625 parts built in the AMMT, where material, scan strategy, and laser processing parameters were replicated.  Parts include a simple horizontal cylindrical cutout and overhang feature.  Melt pool monitoring was conducted at 10 kHz, and layer imaging uses three different illumination angles, resulting in size images per layer.
  • Example use cases: Zhang et al. 2023Lane et al. 2022;
Digital scan strategy command (laser ‘on’ in red) for OverhangPartX4 build, showing every 10 layers.

AM Bench 2022 – Thermography of Single Tracks and Pads (AMB2022-03)

  • Data description: https://data.nist.gov/od/ds/mds2-2716/2716_README.txt
  • Data DOI and download: https://doi.org/10.18434/mds2-2716
  • Summary:  Thermography data pertaining to individual laser tracks on bare metal plates of IN718 with different laser power, speed, and diameter settings. Also, arrays of adjacent laser tracks (pads) on bare metal plates of IN718. 
  • Note:  Detailed descriptions are found here.  Refer to the AM-Bench web page for accessing additional ex-situ characterization data for these experiments.  Users may be most interested in ex-situ characterization of track and pad melt pool cross-sectional geometry found here.
  • Example use cases:
Raw thermographic data of the 'Ypad1' set of laser scans

  • Data DOI and download: https://doi.org/10.18434/mds2-2309
  • Summary: XCT image slice data and files generated from post-build X-ray computed tomography (XCT) measurements of the sixteen parts built as part of the “Overhang Part X16” in-situ monitoring dataset.
