Multi-process additive manufacturing of multilayer metal components

PROJECT DETAILS:

McGill University and Memorial University of Newfoundland will collaborate with Hatch Ltd. and Polycontrols to advance the manufacturing approach for bubbler structures. These multilayer composite metal components, traditionally produced via mechanical pressing, welding, brazing, or coating, will now be developed using additive manufacturing (AM) through a two-step process. This advancement will be enabled by a deeper understanding of the conditions required to fabricate multilayer structures from optimized materials, ensuring their mechanical strength, thermal performance, and resistance to spontaneous ignition. Concurrently, the project will investigate broader aspects of AM in the production of bilayer structures, laying the groundwork for a wider range of future applications.

No new business spin-off is expected; however, Hatch will develop the required intellectual property to update a patent and modernize the sprayer manufacturing process, while Polycontrols will gain the expertise needed to operate as an SME producing these bubbler components.

Hatch and Polycontrols will benefit from the development of both the technology and the associated material supply chain, enabling the domestic manufacture of these devices in Canada—particularly in Quebec—rather than relying on foreign suppliers. In addition, this project will provide advanced training for one postdoctoral fellow, two PhD students, three interns, and one technician.
