Fused Filament Fabrication (FFF) is a popular additive manufacturing (AM) technique that enables quick fabrication of 3D parts through layer-by-layer deposition of melted thermoplastic filament. Industrially-approved FFF technology mostly operates in a closed-source mode (i.e., no change of printing parameters is permitted by the user, limited to the printing materials provided by the printer supplier) and is very expensive when compared to open-source FFF. The main objective of our project is to develop new materials while improving open-source printing processes aiming at manufacturing industry-approved composite parts with a significantly reduced manufacturing and materials costs. The main outcomes of this project will be: (O1) the formulation and characterization of high-performance composite materials featuring high mechanical and thermal performance for the FFF manufacturing, and (O2) the advancement of the open-source FFF process that enables a higher manufacturing flexibility (e.g., new composite formulations) and higher productivity (i.e., improved printing speed and size) for manufacturing composite sandwich panels (composed of 2 facesheets and a core) with the required performance for aerospace applications. The inventions ensued from this project will drive the advancement of the FFF process in an open-source environment to bring new opportunities for the Canadian manufacturing industry. This proposed project is a collaborative research work between Polytechnique Montreal's research team, NRC's Automotive and Surface Transportation (AST) Research Centre located in Boucherville (QC) and two industrial partners, Safran Tech and Solaxis Ingenious Manufacturing Inc. This project will provide a training of 2 PhD students and 6 undergraduate interns in advanced additive manufacturing that will help support our industry and help Canada to be competitive in this emerging field, and will generate important knowledge advancements in various fields including thermoplastic composites, additive manufacturing, and aerospace-graded materials. This partnership will stimulate the full supply chain in AM of thermoplastic composites in Québec and Canada.

熔丝制造 (FFF) 是一种流行的增材制造 (AM) 技术，可通过逐层沉积熔融热塑性长丝来快速制造 3D 零件，工业上认可的 FFF 技术主要以闭源模式运行（即，用户不允许更改打印参数，仅限于打印机供应商提供的打印材料），并且与开源 FFF 相比非常昂贵。我们项目的主要目标是在改进的同时开发新材料。开源打印工艺旨在制造行业认可的复合材料零件，并显着降低制造和材料成本。该项目的主要成果将是：（O1）具有高机械和热性能的高性能复合材料的配方和表征。用于 FFF 制造，以及 (O2) 开源 FFF 工艺的进步，可实现更高的制造灵活性（例如，新的复合材料配方）和更高的生产率（即，改进的打印速度和尺寸），用于制造复合材料夹芯板（由共 2 个该项目的发明将推动开源环境中 FFF 工艺的进步，为加拿大制造业带来新的机遇。蒙特利尔理工学院的研究团队、位于 Boucherville (QC) 的 NRC 汽车和地面运输 (AST) 研究中心以及两个工业合作伙伴 Safran Tech 和 Solaxis Ingenious Manufacturing Inc. 之间的合作。该项目将为先进增材制造领域的 2 名博士生和 6 名本科生实习生将有助于支持我们的行业并帮助加拿大在这一新兴领域保持竞争力，并将在包括热塑性复合材料、增材制造和航空级材料在内的各个领域产生重要的知识进步。此次合作将刺激魁北克和加拿大热塑性复合材料增材制造的全链条供应。
