Design and 3D printing of lightweight architected materials: Characterization of FDM, SLA, SLS, and CBAM prototypes

安讯士原型公司是一家领先的加拿大3D打印公司，提供高质量的增材制造服务，从熔融存款建模（FDM）到立体光刻（SLA）和选择性激光烧结（SLS），适用于航空航天和汽车行业。在这些应用中，多功能和减重是结构部件的主要设计策略。安讯士原型旨在为设计和制造具有高能量吸收能力的轻质结构部件提供3D打印服务。其中一个有前途的解决方案是利用3D打印的轻质结构细胞固体的潜力。然而，需要评估该公司可用的3D打印设备制造的建筑蜂窝材料的机械性能，耐用性和制造成本，特别是由碳纤维增强复合材料制成的3D打印组件。本研究项目的研究目标是设计、模拟和表征由聚合物和纤维增强复合材料制成的3D打印轻质先进材料，设计和表征由蜂窝芯制成的3D打印轻质建筑夹层板，并优化3D打印参数，以提高轻质建筑3D打印材料的结构性能。全球3D打印行业的收入预计将从2013年的30亿美元增长到2020年的210亿美元。因此，拟议中的轻质建筑材料研究将使安讯士原型公司和加拿大先进制造业保持在制造创新、成本效益高的3D打印产品的前沿，同时也将允许麦吉尔的团队在这项研究中合作，应用他们在计算力学和先进细胞固体多物理模拟方面的专业知识，为增材制造的结构特性开发一个预测模型。建筑材料通常包含3D打印缺陷。转让的技术还将通过吸引汽车、航空航天和建筑领域的客户来扩大公司的市场规模，并将为加拿大经济的增长做出贡献。

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.
