could be replaced by polymer-based composites with similar mechanical properties but lower mass.Hutchinson Aerospace & Industry Ltd, a company providing smart solutions for the automotive and aerospaceindustry, aims to develop the 3D printing of complex-shaped brackets for aircraft interior panels using fuseddeposition modeling (FDM) in their research facility located in Montreal.Additive manufacturing, or 3D printing, enables the fabrication of complex geometries without the need forany type of tooling, significantly lowering the fabrication cost for low to medium volume production. Thecompany has expressed great interest in the continuation of the collaboration with LM2 to further develop 3Dprintable polyamide-based composite brackets. During a six-month Engage Plus project, a research associate(RA), Linus Lehnert, will continue to work in close collaboration with Hutchinson to further develop, as wellas create new composite formulations that meet the necessary requirements of the industrial partner.The specific project objectives are to (1) design a new composite formulations to enhance the mechanicalproperties of polyamide (PA) matrix while meeting aerospace requirements, (2) enable the 3D printing of thedeveloped composite, (3) perform material characterization to define optimal manufacturing parameters, (4)fabricate 3D printed brackets and evaluate their performance, and (5) outline and create a detailed work plan tosetup a long-term research project regarding additive manufacturing for aerospace applications betweenHutchinson and LM2. During this Engage Plus project, PA based composites containing glass-fiberreinforcements will be fabricated and interior hardware will be printed on an FDM 3D printing system. Theoutcomes of this collaboration will certainly contribute to the development of lightweight 3D printable bracketsuseful for airplane interior panels by Hutchinson, which will help the company to enter the market of 3Dprinting of aerospace parts.
