Additive manufacturing of heat-sensitive polymer melt using a pellet-fed material extrusion (2018)
Journal Article
Zhou, Z., Salaoru, I., Morris, P., & Gibbons, G. J. (2018). Additive manufacturing of heat-sensitive polymer melt using a pellet-fed material extrusion. Additive Manufacturing, doi:10.1016/j.addma.2018.10.040

The most common method for Additive Manufacturing (AM) of polymers is melt extrusion, which normally requires several pre-processing steps to compound and extrude filament feedstock, resulting in an overall long melt residency time. Consequently a ty... Read More

Development of three-dimensional printing polymer-ceramic scaffolds with enhanced compressive properties and tuneable resorption (2018)
Journal Article
Zhou, Z., Cunningham, E., Lennon, A., McCarthy, H. O., Buchanan, F., & Dunne, N. (2018). Development of three-dimensional printing polymer-ceramic scaffolds with enhanced compressive properties and tuneable resorption. Materials Science and Engineering: C, 93, (975-986). doi:10.1016/j.msec.2018.08.048. ISSN 0928-4931

In this study, bone tissue engineered scaffolds fabricated via powder-based 3D printing from hydroxyapatite (HA) and calcium sulphate (CaSO4) powders were investigated. The combination of using a fast resorbing CaSO4 based powder and the relatively s... Read More
