This file is a 3D reconstructed X-ray CT dataset, which shows particles contained in a Binder Jet printed sample. The full details of the manufacturing process, and the image acquisition and analysis are described in our publication "Micro-X-Ray-CT for Analysis of Particle Size Segregation during Powder Spreading in Binder Jet Printing" (J.Behnsen, J. Roberts, O. Rogan, J. McArdle, K. Black).

This specific dataset shows a high-resolution (2.01 microns voxel size) ROI scan from a sample printed at the front of the powder bed, at a powder spreading speed of 150 mm/s.

The data was collected with the Zeiss Xradia Versa 620 instrument, using the 4X objective with a detector binning of 2 and and exposure time of 2.5s per projection. The source energy settings were 80kV and 10W, and the LE3 beam filter was inserted.
The scan compromised of 1601 projection images over 360 degrees. The data was reconstructed with Zeiss Scout-and-Scan Reconstructor 16.7, with DeepRecon image improvement to reduce noise.

The file format is the original Zeiss file format, which can be read with dedicated image analysis software, such as Dragonfly (Comet-ORS), Avizo (Thermo-Fisher) or VGStudio. An open-source reader for ImageJ/Fiji from Brian Metscher is available on Zenodo: https://doi.org/10.5281/zenodo.10580258
