Metal additive manufacturing has today demonstrated a strong potential for producing small-dimension (= 1m), very complex parts, offering increased performance with a major saving in weight (up to 80% for certain parts), especially when coupled with topological optimization techniques for the design of parts. Unfortunately, the current processes involving the melting of materials are limited for large components using high strength aluminum alloys, thus limiting their use. Cold spray is a technique for depositing material in the solid state capable of depositing with very few constraints, benefiting in particular from a high deposition rate (several kg / h). Its other advantages make this technique particularly attractive for overcoming the limitations of fusion based additive manufacturing processes. The McGill University-NRC cold spray facility, created in 2007, has positioned itself as a world leader in the development of additive manufacturing by cold spray of all metals. However, significant challenges remain in applying this process on a large scale and in physically and economically viable ways with aluminum alloys of interest to the transport industry, e.g. Al 6061 or Al7075.This project, which brings together the NRC, McGill University, ETS and members of the industrial group of METALTec, aims to develop and demonstrate the potential of additive manufacturing by cold spraying for large components (up to several meters in length) using high performance aluminum alloys. The project will focus in particular on the implementation of an innovative solution for the cold spraying of high performance aluminum alloys, while developing material and digital solutions to measure, model and control the evolution of geometry, online, of the 3D part to be produced. The success of this project will be based on the combination of McGill-NRC's expertise in cold spraying, NRC's expertise in process simulation and 3D vision and ETS's knowledge in metrology mechanical simulation. The project is connected with industry via the more than 29 METALTec members forming a network around metal fabrication for the transport industry, covering the entire value chain, from raw materials finished products, in Quebec, Canada and international.

今天，金属添加剂制造具有强大的产生小尺寸（= 1m），非常复杂的零件，可提高性能，并节省重量（某些零件最多80％），尤其是当零件设计的拓扑优化技术加上拓扑优化技术时。不幸的是，对于使用高强度铝合金的大型组件，涉及材料熔化的当前过程受到限制，从而限制了它们的使用。 冷喷雾是一种将材料沉积在固态下的技术，能够在很少的约束下沉积，尤其是从高沉积速率（几千克 /小时）中受益。它的其他优势使得这项技术在克服基于融合的添加剂制造过程的局限性方面特别有吸引力。 McGill University-NRC冷喷雾设施成立于2007年，已将自己定位为全金属的添加剂制造的世界领导者。然而，在大规模以及以物理和经济上可行的方式运用这一过程，以及对运输行业感兴趣的铝合金，例如AL 6061或AL7075。该项目将NRC，McGill University，ETS和Metaltec工业组的成员汇集在一起​​，旨在使用高性能铝合金来开发和证明通过冷喷涂大型组件（长达几米）的冷喷涂添加剂制造的潜力。该项目将特别集中在实施高性能铝合金的创新解决方案上，同时开发材料和数字解决方案，以测量，建模和控制要生产的3D部分的几何发展，在线，在线，在线。 该项目的成功将基于McGill-NRC在冷喷涂方面的专业知识，NRC的过程模拟和3D视觉方面的专业知识以及计量机械模拟方面的知识的结合。该项目通过29多个Metaltec成员与行业联系，在魁北克省，加拿大和国际公司的原材料成品制成产品中涵盖了整个价值链，涵盖了整个价值链，涵盖了整个价值链。
