Curvature-based segmentation of powder bed point clouds for in-process monitoring (2018)
Conference Proceeding
Chung Chee Law, A., Southon, N., Senin, N., Stavroulakis, P., Leach, R., Goodridge, R., & Kong, Z. (2018). Curvature-based segmentation of powder bed point clouds for in-process monitoring. In 29th Annual International Solid Freeform Fabrication Symposium - an Additive Manufacturing Conference 2018

This paper presents a curvature-based analysis of point clouds collected in-process with fringe projection in a polymer powder bed fusion process. The three-dimensional point clouds were obtained from outside of the build chamber with a fringe projec...

In-process measurement and monitoring of a polymer laser sintering powder bed with fringe projection (2018)
Journal Article
Southon, N., Stavroulakis, P., Goodridge, R., & Leach, R. (2018). In-process measurement and monitoring of a polymer laser sintering powder bed with fringe projection. Materials and Design, 157, 227-234. https://doi.org/10.1016/j.matdes.2018.07.053

We investigate the feasibility of using fringe projection to monitor the powder bed of a polyamide 12 polymer laser sintering machine. In particular, we demonstrate the ability of fringe projection to identify a number of defects arising during the p...

Laser sintering of nano-hydroxyapatite coated polyamide 12 powders (2018)
Journal Article
Hui, D., Goodridge, R. D., Scotchford, C., & Grant, D. M. (2018). Laser sintering of nano-hydroxyapatite coated polyamide 12 powders. Additive Manufacturing, 22, 560-570. https://doi.org/10.1016/j.addma.2018.05.045

As part of a larger study on the laser sintering (LS) of nano-composite structures for biomedical applications, a wet mixing method was used to coat Polyamide 12 (PA12) particles with nano-hydroxyapatite (nHA). The addition of nHA significantly affec... Read More about Laser sintering of nano-hydroxyapatite coated polyamide 12 powders.
