Recent studies have shown that X-ray computed tomography (XCT) can be used to measure the surface topography of additively manufactured parts. However, further research is necessary to fully understand XCT measurement performance. Here, we show how m...

Noise evaluation of a point autofocus surface topography measuring instrument (2018)
Journal Article
Maculotti, G., Feng, X., Galetto, M., & Leach, R. K. (2018). Noise evaluation of a point autofocus surface topography measuring instrument. Measurement Science and Technology, 29(6), https://doi.org/10.1088/1361-6501/aab528

In this work, the measurement noise of a point autofocus surface topography measuring instrument is evaluated, as the first step towards establishing a route to traceability for this type of instrument. The evaluation is based on the determination of... Read More about Noise evaluation of a point autofocus surface topography measuring instrument.

Internal surface measurement of metal powder bed fusion parts (2018)
Journal Article
Thompson, A., Senin, N., Maskery, I., Körner, L., Lawes, S., & Leach, R. (2018). Internal surface measurement of metal powder bed fusion parts. Additive Manufacturing, 20, https://doi.org/10.1016/j.addma.2018.01.003

Recent advances in X-ray computed tomography (XCT) have allowed for measurement resolutions approaching the point where XCT can be used for measuring surface topography. These advances make XCT appealing for measuring hard-to-reach or internal surfac... Read More about Internal surface measurement of metal powder bed fusion parts.
