Enhancing Naval Materiel Support with Additive Manufacturing

Event Date:
Start at 1:00 PM
May 5, 2023

A webinar by the IMarEST’s Naval Engineering Special Interest Group.

This webinar will provide an overview of the journey Canada’s Department of National Defence has taken to leverage Additive Manufacturing technology to enhance materiel support for the Royal Canadian Navy. The presentation will include examples of Additive Manufacturing applications that have been pursued to improve fleet material support, and the vision for future applications in the naval environment. It will also include a discussion of ongoing efforts to integrate Additive Manufacturing technology and related certification processes into Canada’s naval materiel management policy framework.


Mark Sheppard, Director Naval Platform Systems, Department of National Defence, Canada


Dr James Huang, Sub-Section Head Naval Materials & Petroleum, Department of National Defence, Canada

Dr Huang completed his PhD in Materials Science and Engineering at The University of British Columbia (UBC) after which he became a Research Engineer at UBC studying the precipitation behaviour of aluminum alloys. This led to a position as Laboratory Manager at UBC where he managed the microstructure characterization laboratory in the Advanced Materials and Process Engineering Laboratory (AMPEL).

After nearly a year at UBC, Dr Huang spent eight months as a Visiting Fellow at the Canadian Neutron Beam Centre in Chalk River, Ontario, where he conducted neutron scattering and tomography research on nuclear reactor system components. Following that, Dr Huang joined the Department of National Defence, first as a Defence Scientist at the Dockyard Laboratory in the Defence Research and Development Canada (DRDC) in Halifax, Nova Scotia. In this role, he was deeply engaged in scientific support to the Royal Canadian Navy (RCN) surface and submarine fleet. He was also engaged in the development, testing and evaluation of a wide variety of engineering solutions related to naval platform structural integrity issues, particularly, metallurgy, welding, fracture, fatigue, and non-destructive testing (NDT). After gaining an in-depth understanding of the naval platform materials, he took a position as the Subject Matter Expert at the National Defence Headquarters in Ottawa, where he supported the RCN fleet field with exposure to a broader horizon in the naval platform material field.

Most recently James was appointed as SubSection Head of DNPS 2-4 where he managed a portfolio of Naval Materials Engineering. In this role, he oversees the development of innovative technologies for the maintenance of the RCN submarine and surface fleet, in addition to the engineering service delivery in the relevant areas, and administration of the design intent of the naval vessels, material engineering standards, and the fleet material issues. He is also responsible for submarine safety licensing in the related disciplines, and the maintenance of material evaluation capabilities such as explosion bulge testing. In this appointment, he sponsored a considerable number of projects involving many collaborators from other government departments and agencies, and the private industry. The collaborations have yielded patentable technologies and produced engineering solutions for the assessment of key naval platform system components.
