Research Program: Precision and Freeform Fabrication Technologies

The primary objective of the core research program is to conduct leading edge research and effectively develop innovative rapid manufacturing processes to reduce cost and time and to improve the functionality or extend the life of components. The goals of this program are to increase the competitive advantage of Canadian manufacturers.

Solid Shaping Processes

Research is being performed on processes and systems to form 3D solid shapes with specialized materials. New and cost-effective solutions are being developed for the production of functional prototypes, production tools and composite components through electro-chemical processing and precision casting. New composite fabrication processes based are being developed to produce moulds and components with better surface finish and improved performance. Examples of applications include: titanium-based nanocomposites, tooling for injection moulding, composite components and hydrogels.

Novel chemical/electrochemical coatings and surface texturing of components are being developed to improve functional properties. The research covers surface preparation and activation techniques, as well as compatibility and quality of the deposited material at the interface of different layers with the substrate material. For example, the systems are to produce chemobiomimetic hydroxyapatite (HA) coating on titanium alloys, to refine surface grain of titanium alloys, and to produce coatings on magnesium alloys.

Key words: rapid manufacturing, precision casting, electrochemical processes, deposition of functional coatings
