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.

融合细丝制造（FFF）是一种流行的添加剂制造（AM）技术，可以通过融化的热塑性细丝的一层沉积来快速制造3D零件。工业批准的FFF技术主要以封闭式模式运行（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），与开放源FFF相比，它非常昂贵。我们项目的主要目的是开发新材料，同时改善开源印刷工艺旨在旨在以行业批准的复合零件，并大大降低了制造和材料成本。 The main outcomes of this project will be: (O1) the formula 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 formulas) and higher production (i.e., improved printing speed and size) for manufacturing composite sandwich panels (composed of 2面孔和核心）具有航空应用所需的性能。该项目发生的事件将推动FFF流程在开源环境中的进步，为加拿大制造业带来新的机会。这个提议的项目是位于布切维尔（QC）的NRC的汽车和地面运输（AST）研究中心与两个工业合作伙伴之间的合作研究工作领域，并将在包括热塑性组成，成瘾性制造和航空航天级的材料在内的各个领域产生重要的知识进步。这种合作伙伴关系将刺激魁北克和加拿大热塑性成分的AM中的全部供应链。
