Frederico Rossi Kaschel
Frederico R. Kaschel is a PhD Researcher in I-Form. He received his MSc at University College Dublin in 2017, where he studied Biomedical Engineering. His thesis was focused on the comparison of different light sources and adhesives for pen needle application, working closely with Becton Dickinson (BD Medical). Using the production scale metal additive system (RenAM500M), his PhD research focus revolves around in-process and post-process optimisation of Ti-6Al-4V alloy, with the aim of optimising the manufacturing process and the thermal treatment process.
Research Interests (Lay Summary)
Frederico started his PhD with I-Form in 2017 in the area of metal Additive Manufacturing (AM). He is investigating the effect that key parameters of the AM printing and post-printing thermal treatment processes have on both the mechanical performance and micro/nano-structure of parts. This research area is of particular interest due to the increase in the use of 3D printing technologies in the manufacture of application-specific metallic parts such as dentures and orthopaedic implants. In researching both in-process and post-processing conditions by using in-situ characterisation techniques, Frederico is attempting to understand the effect certain processing conditions have on the crystal structure and respective mechanical performance of parts. This means that optimisation of the current processes can be achieved to yield superior AM parts.
The aim of Frederico’s work is to gain an in-depth understanding into how specific in-process and post-processing conditions influence the mechanical properties of AM parts due to changes in the crystal lattice. Through in-situ characterisation techniques, the step-wise crystal transformation during heating can be observed, analysed and applied to optimise the overall part performance. Understanding how the crystal structure of the metal alloy changes during heating is of particular interest as post-thermal treatment is readily applied to AM parts after manufacturing to ensure parts comply with ASTM standards. By examining the changes in crystal structure and respective mechanical performance of parts, an adequate post-thermal treatment cycle can be formulated to achieve superior mechanical properties of parts for specific end-use applications.
