Targeted rework strategies for powder bed additive manufacture (2017)
Journal Article
Hirsch, M., Dryburgh, P., Catchpole-Smith, S., Patel, R., Parry, L., Sharples, S., …Clare, A. (2018). Targeted rework strategies for powder bed additive manufacture. Additive Manufacturing, 19, 127-133. https://doi.org/10.1016/j.addma.2017.11.011

A major factor limiting the adoption of powder-bed-fusion additive manufacturing for production of parts is the control of build process defects and the effect these have upon the certification of parts for structural applications. In response to thi... Read More about Targeted rework strategies for powder bed additive manufacture.

Fractal scan strategies for selective laser melting of ‘unweldable’ nickel superalloys (2017)
Journal Article
Catchpole-Smith, S., Aboulkhair, N., Parry, L., Tuck, C., Ashcroft, I., & Clare, A. (in press). Fractal scan strategies for selective laser melting of ‘unweldable’ nickel superalloys. Additive Manufacturing, https://doi.org/10.1016/j.addma.2017.02.002

The high thermal gradients experienced during manufacture via selective laser melting commonly result in cracking of high γ/γ′ Nickel based superalloys. Such defects cannot be tolerated in applications where component integrity is of paramount import...
