About
Thomas Gillick
Postgraduate Researcher
DCU
Thomas Gillick is a PhD researcher in I-Form and is based in Dublin City University (DCU). He is working on the additive manufacturing (3D-Printing) of nickel-titanium alloys. He graduated with a MEng and BEng in Biomedical Engineering from DCU in 2023. His main area of research is on residual stresses that develop during the additive manufacturing of metals.
Technical Summary
Residual stresses are stresses that develop and remain within metallic parts during the additive manufacturing (3D-Printing) process. These stresses develop due to the rapid heating and cooling experienced by the printing material, as it is being scanned by a laser during the printing process. The development of these stresses causes undesirable effects in the printed parts, which includes part distortion as well as diminished material strength. To minimise the amount of residual stress that develops in parts during the printing process, Thomas is investigating the variation of processing parameters that are used during the printing process, in order to identify a set of parameters that minimises the amount of residual stress that develops during printing.
