Direct Writing Unclonable Watermarks with an Electrochemical Jet (2022)
Journal Article
Speidel, A., Bisterov, I., & Clare, A. T. (2022). Direct Writing Unclonable Watermarks with an Electrochemical Jet. Advanced Functional Materials, 32(51), Article 2208116. https://doi.org/10.1002/adfm.202208116

Counterfeit parts result in significant losses per annum and are often dangerous, therefore they represent a serious concern for manufacturers and end users alike. Easily written but unclonable watermarks undermine the proposition of the counterfeite... Read More about Direct Writing Unclonable Watermarks with an Electrochemical Jet.

Electrolytic-dielectrics: A route to zero recast electrical discharge machining (2022)
Journal Article
Ahmed, S., Speidel, A., Murray, J. W., Ahmed, N., Cuttell, M., & Clare, A. T. (2022). Electrolytic-dielectrics: A route to zero recast electrical discharge machining. International Journal of Machine Tools and Manufacture, 181, Article 103941. https://doi.org/10.1016/j.ijmachtools.2022.103941

Electrical discharge machining (EDM) is a widely used manufacturing process for machining hard or high melting point metals. A characteristic feature of this process is a brittle, porous and rough recast layer on machined surfaces, which undermines i...

Chemical recovery of spent copper powder in laser powder bed fusion (2022)
Journal Article
Speidel, A., Gargalis, L., Ye, J., Matthews, M. J., Spierings, A., Hague, R., …Murray, J. W. (2022). Chemical recovery of spent copper powder in laser powder bed fusion. Additive Manufacturing, 52, Article 102711. https://doi.org/10.1016/j.addma.2022.102711

In laser powder bed fusion (LPBF), recovered unfused powder from the powder bed often degrades upon sequential processing through mechanisms like thermal oxidation and particle satelliting from ejected weld spatters and particle-laser interactions. G... Read More about Chemical recovery of spent copper powder in laser powder bed fusion.
