In an exclusive interview during the PANNDT Conference 2025, Karl Jauvin, NDT Trainer at the Centre de Métallurgie du Québec(CMQ), shared details about the center’s innovations in metal 3D printing, destructive and non-destructive testing, as advanced technologies for the metalworking industry.
Metal 3D printing technologies
Jauvin explained that CMQ operates as an applied research center, focused on solving real technical challenges for companies in various sectors. They also use technologies such as 3D printing with metalsthermal projection and computational simulation to manufacture industrial components, from conceptualization to final product. In addition, they perform extensive testing to ensure material quality and reliability.
Moreover, the use of 3D printing with metal powders, such as aluminum and titanium, allows them to create complex parts and optimize the use of energy such as thermal deformation, with respect to traditional welding processes.
“We can design customized parts and even generate our own alloys, atomize them into powder and fabricate them directly,” Jauvin explained. This technique has even been applied to industrial piping, facilitating repairs with minimal dimensional alteration.
CMQ also works with advanced thermal spray coating technologies, using materials such as ceramics and even diamond, to provide additional protection against friction and wear on components exposed to extreme conditions.
Although based in Quebec, the center offers its services internationally, collaborating with clients in Germany and other countries, while actively integrating undergraduate and graduate students in its projects, fostering innovation and professional development.
As a nod to the Canadian context and in the midst of the NHL playoffs, Jauvin showed a 3D printed metal trophy, made using cold metal transfer technology, praising the versatility of the process and its appeal at technology fairs.
