Australian manufacturers of 3D printed titanium products face grand challenges in affordably producing useable and reliable as-printed products because the 3D printing process may create unfavourable material characteristics. To ensure products meet acceptance criteria, manufacturers usually apply expensive and time-consuming post processes such as heat treatment. This project aims to discover how alloy composition can be modified to produce more favourable material characteristics directly from 3D printing, preventing the need for post processing. Australian manufacturers will likely benefit through a streamlined manufacturing process resulting in increased profitability in existing markets as well as expansion into new global markets.Read moreRead less

This project aims to develop a predictive theory of strength for unflawed, low-ductile porous materials – an unsolved problem in computational solid mechanics. Three-dimensional printing of lightweight, porous materials is used in industry, medicine and science.

High-density three-dimensional integrated circuits used in microelectronic devices are evolving and placing increasing demands on micro-solder joints. Tin based lead-free solder alloys require further development to satisfy performance requirements, particularly with respect to the properties of the intermetallic forms between solder and substrate. This project investigates the mechanical properties and deformation mechanisms of intermetallic forms with trace element additions using micro-pillar compression and ultra-high voltage transmission electron microscopy. Beyond the development of techniques transferable to similar research, this project will lead to significant intellectual property relating to solder composition.Read moreRead less
