Considerations during pulse laser based additive manufacturing of high melting point materials

增材制造（AM）是指通过以逐层方式控制添加材料来构建3D对象以生产最终形状或接近最终形状的对象的新兴技术。这种颠覆性技术预计到2025年，加拿大AM产品市场将达到约140亿美元/年，这在航空航天工业中具有重要意义，其中出现了一系列示例：商用GE LEAP燃料喷嘴，波音优化结构支架等。在这方面，雷尼绍和Brochu教授在不同的项目中是合作伙伴，以推动技术壁垒。在目前的提案中，该团队建议研究AM加工中涉及的基本方面，例如粉末表征，固化和加工以及残余应力的发展，以定义加工过程，以开发新的AM材料，特别是高温高温合金。Brochu教授还将通过结合AM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所有行业中AM技术的采用率，这些行业都有Rensikind作为设备供应商，Renishaw Canada作为技术支持。此外，该项目还将培训六名懂AM的HQP，强制采用这种颠覆性技术。

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.
