This project aims at the laser powder-bed fusion (LPBF) of Titanium-5553 for deploying to landing gear systems. LPBF is a class of additive manufacturing (AM) that has provided tremendous opportunities for various industries such as aerospace, tooling and automotive. Given the opportunities provided by LPBF and also the importance of the deployment of this technology for making aerospace parts with lower weight and better load bearing, a pilot study was initiated in early 2018 between the University of Waterloo and Safran Landing Systems Canada Inc. to investigate the feasibility of LPBF of Ti-5553 coupon samples for physical properties measurements. Given the promising results of the pilot study, this collaborative project is proposed to address several remaining challenges including holistic characterizations of the LPBF process for Ti-5553 through a screening phase and design of experiments, a thorough characterization of the LPBF-made specimens, durability/repeatability investigation, and dynamic and static tests of the printed parts. The project has three work packages: 1)WP1: Design of Experiments and process optimization; WP2: Mechanical testing and analysis of process optimized parts; and, WP3: Creating a real aerospace part with optimum parameters. The benefit of LBPF of landing gear parts is tremendous. The printed parts can be redesigned to benefit from design flexibility and parts consolidation that AM offers, thus becoming lighter and in turn, minimize fuel consumption in airplanes. In addition, LBPF can be deployed for low-volume manufacturing of such parts in a longer term, as the fabrication costs will drop through consolidation of parts in one print. The outcome of this technology, if successful, will be pervasive and will have a deep and broad impact. Many industries will benefit from the deployment of LPBF to Ti5553, with the most immediate example beyond aerospace being the maritime industry, for their integrated offshore oil rigs. Successful outcomes will also be of tremendous importance to our industrial partner, Safran, which intends to expand its activities to the AM processes and printed high-valued components.

该项目旨在将钛-5553激光粉末床聚变（LPBF）用于部署到起落架系统。LPBF是一类增材制造（AM），为航空航天、模具和汽车等各个行业提供了巨大的机会。鉴于LPBF提供的机会以及部署该技术对于制造重量更轻、承载更好的航空航天部件的重要性，滑铁卢大学和赛峰着陆系统加拿大公司于2018年初启动了一项试点研究。研究Ti-5553试样LPBF用于物理性能测量的可行性。鉴于试点研究的良好结果，提出了这个合作项目，以解决几个剩余的挑战，包括通过筛选阶段和实验设计，LPBF制造的标本，耐久性/可重复性调查，以及动态和静态测试的LPBF过程的Ti-5553的全面表征。该项目有三个工作包：1）WP 1：实验设计和工艺优化; WP 2：工艺优化零件的机械测试和分析;以及WP 3：创建具有最佳参数的真实的航空航天零件。 起落架部件的LBPF的好处是巨大的。打印部件可以重新设计，以受益于AM提供的设计灵活性和部件整合，从而变得更轻，从而最大限度地减少飞机的燃油消耗。此外，LBPF可以在较长时间内用于此类零件的小批量制造，因为通过将零件合并在一次打印中，制造成本将下降。 这项技术的成果，如果成功，将是普遍的，并将产生深刻和广泛的影响。许多行业将受益于LPBF到Ti 5553的部署，除了航空航天之外，最直接的例子是海运业，因为他们的集成海上石油钻井平台。成功的结果对我们的工业合作伙伴赛峰集团也具有巨大的重要性，赛峰集团打算将其活动扩展到增材制造工艺和印刷高价值部件。
