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

增材制造（AM）是指一种新兴的技术，它通过以一层一层的方式控制材料的添加，以生产达到或接近最终形状的物体，从而构建3D物体。预计到2025年，这一颠覆性技术将使加拿大的增材制造产品市场达到每年140亿美元，这将对航空航天工业产生重大影响，其中一系列例子正在出现：商用GE LEAP燃料喷嘴，波音优化结构支架等。了解AM如何处理新的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，共同推动技术壁垒。在目前的提案中，该团队建议研究增材制造过程中涉及的基本方面，如粉末表征，凝固和加工，以及残余应力的发展，以确定加工信封，以打开新的增材制造材料，特别是高温高温合金。Brochu教授还将通过结合AM的各种投入之间的竞争和全球互动来扩大他的研究组合。这项研究的传播将有助于提高加拿大在所有行业AM技术采用率方面的地位，这些行业有雷尼绍作为设备供应商和雷尼绍加拿大作为技术支持。此外，该项目将培训6名精通am的hqp，强制采用这一颠覆性技术

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.**
