Journal Article
Baumers, M., Tuck, C., Wildman, R. D., Ashcroft, I., & Hague, R. J. (in press). Shape complexity and process energy consumption in electron beam melting: a case of something for nothing in additive manufacturing?. Journal of Industrial Ecology, https://doi.org/10.1111/jiec.12397

Additive manufacturing (AM) technology is capable of building up component geometry in a layer-by-layer process, entirely without tools, molds, or dies. One advantage of the approach is that it is capable of efficiently creating complex product geome...
