Review of material measures for surface topography instrument calibration and performance verification (2023)
Journal Article
Pappas, A., Newton, L., Thompson, A., & Leach, R. (2024). Review of material measures for surface topography instrument calibration and performance verification. Measurement Science and Technology, 35(1), Article 012001. https://doi.org/10.1088/1361-6501/acf1b9

As the need for the manufacturing of complex surface topographies increases, traceable measurement with known uncertainties can allow a manufacturing process to remain stable. Material measures are the link in the chain that connects the surface topo... Read More about Review of material measures for surface topography instrument calibration and performance verification.

Comparison of coherence scanning interferometry, focus variation and confocal microscopy for surface topography measurement (2023)
Conference Proceeding
Hooshmand, H., Liu, M., Pappas, A., Thompson, A., Leach, R., & Piano, S. (2023). Comparison of coherence scanning interferometry, focus variation and confocal microscopy for surface topography measurement.

The most common optical technologies for surface topography measurement are coherence scanning interferometry (CSI), focus variation microscopy (FV) and imaging confocal microscopy (CM). Due to the benefits and drawbacks of each, these instruments ar...

Measurement of powder spreading dynamics in additive manufacturing (2023)
Conference Proceeding
Ferris, S., Thompson, A., Maskery, I., Hall, S., & Piano, S. (2023). Measurement of powder spreading dynamics in additive manufacturing.

In this work, we examine the effect of the state of the pre-processing powder bed in powder-based additive manufacturing, particularly in metal laser powder bed fusion (PBF-LB). The spreading of the powder layer has been identified as a critical but... Read More about Measurement of powder spreading dynamics in additive manufacturing.

New Standard for Metal Powder Bed Fusion Surface Texture Measurement and Characterisation (2023)
Journal Article
Thompson, A., Newton, L., & Leach, R. (2023). New Standard for Metal Powder Bed Fusion Surface Texture Measurement and Characterisation. Metrology, 3(2), 237-245. https://doi.org/10.3390/metrology3020013

As metal additive manufacturing has been increasingly accepted as a viable method of industrial manufacture, there has been a significant uptake in manufacturers wishing to verify and test their parts through analysis of part surface. However, variou... Read More about New Standard for Metal Powder Bed Fusion Surface Texture Measurement and Characterisation.

Stable large area drop-on-demand deposition of a conductive polymer ink for 3D-printed electronics, enabled by bio-renewable co-solvents (2023)
Journal Article
Rivers, G., Austin, J. S., He, Y., Thompson, A., Gilani, N., Roberts, N., …Turyanska, L. (2023). Stable large area drop-on-demand deposition of a conductive polymer ink for 3D-printed electronics, enabled by bio-renewable co-solvents. Additive Manufacturing, 66, Article 103452. https://doi.org/10.1016/j.addma.2023.103452

Development of conductive polymer ink formulations with reliable jetting stability and physical properties could offer sustainable routes for scaling-up the 3D-printing of electronics. We report a new poly(3,4-ethylenedioxythiophene) polystyrene sulp...
