Abstract
The fourth industrial revolution has brought many benefits to the mechanical engineering world.
Through data revolution, defect segmentation in complex XCT images can now be automated in a
shorter time while achieving more accurate results. Prior work [1] proves that a deep learning approach
can extract pores from every voxel of 3D XCT data and calculate its porosity with high accuracy.
However, it was established that training a deep learning model with limited data can cause the model
to overfit or have inferior segmentation performance than models that are trained with a larger dataset.
This overfit issue is a common issue in all sorts of data-driven inspections. Often, obtaining raw data
and annotating these raw data for machine learning inspection can take significant resources, shifting
the focus away from the network design and training.
We present XCTPore, an open source database of X-ray CT images containing 2D slices and 3D
volumetric data of X-ray CT scanned additively manufactured components with varying porosity and
image quality. This database is currently maintained by the Advanced Remanufacturing and
Technology Centre (ARTC) and is open to industry practitioners and academic contributors. The
content of the database can be queried through our python code found in our GitHub link
