Complex functional surface design for additive manufacturing (2016)
Conference Proceeding
Morris, S., Dudman, J., Körner, L., Melo, P., Newton, L., & Clare, A. T. (2016). Complex functional surface design for additive manufacturing.

This paper presents a new methodology for the creation of advanced surfaces which can be produced by Additive Manufacturing (AM) methods. Since there is no cost for enhanced complexity, AM allows for new capabilities in surface design. Micro-scale su... Read More about Complex functional surface design for additive manufacturing.

Loose powder detection and surface characterization in selective laser sintering via optical coherence tomography (2016)
Journal Article
Guan, G., Hirsch, M., Syam, W. P., Leach, R. K., Huang, Z., & Clare, A. T. (2016). Loose powder detection and surface characterization in selective laser sintering via optical coherence tomography. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 472(2191), Article 20160201. https://doi.org/10.1098/rspa.2016.0201

Defects produced during selective laser sintering (SLS) are difficult to non-destructively detect after build completion without the use of X-ray-based methods. Overcoming this issue by assessing integrity on a layer-by-layer basis has become an area...
