Ms Axieh Joy Bagasol
Postgraduate Researcher

Axieh Bagasol is a master’s student researcher specialising in characterisation of 3D printed metal alloys, based at UCD. She completed her undergraduate degree in BSc (Ord) Medicinal Chemistry and BSc (Hons) Analytical Chemistry at TUD. Her main research interests are in the areas of metal additive manufacturing, metallurgy, materials characterisation and materials structure (property analysis).

Research Interests (Lay Summary)

Axieh started her postgraduate study with I-Form in 2018. Her research involves understanding the effect of different build conditions on the part quality of 3D printed metals. Her current focus material set is titanium alloys, which are used extensively in many areas due to their superior combination of unique properties such as high strength, corrosion resistance and biocompatibility.

 

Technical Summary

3D printing or additive manufacturing (AM) is a layer-by-layer process that yields the ability to fabricate and customise geometrically complex structures from excellent quality materials. Due to this increased flexibility in manufacturing, medical industries have diverted their interest to this new technology to print controlled porous structures used for orthopaedic implants.

Metal 3D printing still faces many challenges, specifically the wide range of printing factors that can potentially affect the quality of the printed part. Ideally, the goal is to print a part with little or no defects (e.g. gas voids and pores) along with a suitable microstructure to achieve optimised mechanical properties. However, due to the complexity of metal printing, this is often not the case. The aim of Axieh’s research is to evaluate the influence of printing conditions on the resulting part quality, which directly correlates to mechanical performance. A good understanding in this area will help minimise/eliminate defects and obtain better microstructure of titanium alloys. This will ultimately improve the strength of the printed parts and minimise the need for post-processing treatments.
