Research Program: Precision and Freeform Fabrication Processes

The primary objective of the core research program is to conduct leading edge research and effectively develop innovative rapid manufacturing processes to reduce time, cost 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.

Material Additive Processes

Laser consolidation systems are being developed to process functional and high performance materials, including light weight materials and high temperature alloys. The aim is to build solid and complex shapes in one step with laser processing by using the multiple axis motion system, powder delivery and on-line sensing and adaptive control. The systems are used for the laser consolidation and repair of automotive and aerospace lightweight structures, turbine components, die and moulds.

Hybrid laser consolidation and powder forming processes are being developed for the production of complex functional parts. Processing parameters for high-performance materials, composites and other commonly used materials are being optimized with the capability to build walls with variable thickness. The program aims to develop hybrid techniques for building/repairing features on complex components and structures.

Key words: direct digital manufacturing, laser consolidation, powder forming, rapid tooling and prototyping
