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.**

添加剂制造（AM）是指通过以逐层形式对材料进行控制的材料来构建3D对象的新兴技术，以在其最终形状或接近其最终形状的情况下产生对象。预测，到2025年，这种颠覆性技术的AM产品的加拿大市场为约14B $ 14B，这在航空航天行业中将很重要，那里有一系列示例正在出现：商业使用的GE LEAP燃油喷嘴，优化优化的结构支架等。了解AM在现场中如何处理新的化学性能是在该领域中对新的化学作用是一项挑战。在这方面，雷尼沙（Renishaw）和Brochu教授是推动技术障碍的不同计划的合作伙伴。在当前的建议中，该团队提议研究AM加工所涉及的基本方面，例如粉末表征，固化和加工以及剩余应力的发展，以定义加工信封以打开新的AM材料，特别是高温超级合金。 Brochu教授还将通过结合AM的各种投入之间的竞争性但全球互动来增强其研究组合。该研究的传播将有助于提高加拿大在AM技术采用率中的地位，以使所有拥有Rensihaw作为设备供应商和Renishaw Canada的行业作为技术支持。此外，该项目将培训六幅AM-Literate HQP，必须采用这种破坏性技术。**
