Axis Prototypes is a leading Canadian 3D printing company offering high-quality additive manufacturingservices, ranging from fused deposit modelling (FDM) to stereolithography (SLA) and selective laser sintering(SLS) for parts used in aerospace and automotive sectors. In these applications, multifunctionality and weightreduction are major design strategies for structural components. Axis Prototypes aims at offering 3D printingservices for design and manufacturing of lightweight structural components with high energy absorptioncapabilities. One of the promising solutions is to exploit the potential of 3D printed lightweight architectedcellular solids. However, mechanical properties, durability, and manufacturing cost of architected cellularmaterials fabricated by 3D printing facility available in the company need to be evaluated, especially for 3Dprinted components made of carbon fiber-reinforce composites. The research objectives of this research projectare to design, simulate, and characterize 3D printed lightweight advanced materials made of polymers andfiber-reinforced composites, to design and characterize 3D printable lightweight architected sandwich panelsmade of cellular cores, and to optimize 3D printing parameters in order to improve the structural performanceof lightweight architected 3D printed materials. The world-wide 3D printing industry is expected to grow from$3B revenue in 2013 to $21B by 2020. As a result, the proposed research on lightweight architected materialswill keep Axis Prototypes and Canadian Advanced Manufacturing industry on the vanguard of fabrication ofinnovative, cost-effective, 3D printable products, while will allow the McGill's team collaborating in thisresearch to apply their expertise on computational mechanics and multiphysical simulation of advanced cellularsolids to develop a predictive model for structural properties of additively manufacture architected materialswhich commonly contain 3D printing defects. The transferred technology will also increase the company'smarket size by attracting customers in Automotive, Aerospace, and Construction and will contribute to thegrowth of Canadian economy.
