Additive Manufacturing (AM) refers to an emerging class of technologies that build 3D objects by the controlled addition of materials in a layer-by-layer fashion to produce objects at or near their final shape. This disruptive technology is foretasted to have a Canadian market for AM products reaching ~$14B/year by 2025, which will be significant in the aerospace industry, where a series of examples are emerging: commercially used GE LEAP fuel nozzle, Boeing optimized structural brackets, etc. Understanding how new chemistry can be processed by AM is a key challenge in the field. In that respect, Renishaw and Prof. Brochu are partners in different programs to push the technological barriers. In the current proposal, the team proposes to investigate fundamental aspects involved in AM processing, such as powder characterization, solidification and processing, and the development of residual stresses, to define processing envelops to open new AM materials, specifically high temperature Superalloys. Prof. Brochu will also augment his research portfolio by combining competitive but global interactions between the various inputs of AM. The dissemination of the research will contribute to improve Canada's position in adoption rate of AM technologies for all industries having Rensihaw as equipment supplier and Renishaw Canada as technology support. Moreover, this project will train six AM-literate HQPs, mandatory to adopt this disruptive technology.**

增材制造 (AM) 是指一类新兴技术，通过以逐层方式受控添加材料来构建 3D 物体，以生产达到或接近最终形状的物体。预计到 2025 年，这项颠覆性技术的加拿大增材制造产品市场将达到约 14B 美元/年，这对航空航天业意义重大，该行业正在出现一系列例子：商业使用的 GE LEAP 燃料喷嘴、波音优化的结构支架等。了解增材制造如何处理新化学物质是该领域的一个关键挑战。在这方面，雷尼绍和布罗楚教授是不同项目的合作伙伴，旨在突破技术壁垒。在当前的提案中，该团队建议研究增材制造加工涉及的基本方面，例如粉末表征、凝固和加工以及残余应力的发展，以定义加工范围以开辟新的增材制造材料，特别是高温超级合金。 Brochu 教授还将通过结合增材制造各种输入之间的竞争性但全球性的相互作用来扩大他的研究组合。该研究的传播将有助于提高加拿大在以 Rensihaw 作为设备供应商和雷尼绍加拿大公司作为技术支持的所有行业采用增材制造技术方面的地位。此外，该项目将培训六名具备 AM 知识的 HQP，强制他们采用这种颠覆性技术。**
