Nature has always been a great source of inspiration for designers to come up with novel ideas and to improve the performance of engineering materials and structures. Advances in material characterization, computational modeling, and additive manufacturing (AM) have enabled researchers to decipher the intricate microstructure of natural materials and to develop innovative, but manufacturable, architected cellular materials. As an example of cellular materials, gyroid structures found in butterfly wing scales inspires this research project to develop architected shellular materials and fabricate them by AM. Opposed to lattices, which suffer from stress concentration due to the irregularity of their geometrical architectures, shellular materials possess smooth and continuous surfaces that make them an ideal advanced lightweight material with a high energy absorption capability. Due to the coplanar stresses in triply periodic minimal surface (TPMS), architected shellular materials can offer a new class of lightweight stretching-dominated cellular solids with ultrahigh stiffness and energy absorption properties. The objective of this project is to employ AM technology to develop high-performance families of TPMS shellulars with optimized architectures by tuning their geometrical features and resorting to structural hierarchy concept. Considering the enormous potential of architected shellular materials for developing lightweight load-bearing structural elements with energy absorbing and heat exchanging capabilities, Axis Prototypes (a leading Canadian 3D printing company that offers high-quality AM services) sponsors this research project and will directly collaborate with the McGill's research team to design, 3D print, and characterize architected shellular materials to introduce them as novel multifunctional materials for parts used in aerospace, automotive, and energy sectors. Since the number of 3D printing companies in Canada is fast growing, this research project forms a bridge between the developing advanced manufacturing industries and state-of-the-art engineering design and provides a great opportunity for Canadian companies to become leaders in the field of advanced manufacturing of advanced lightweight materials.

大自然一直是设计师提出新思想并提高工程材料和结构的性能的重要灵感来源。材料表征，计算建模和添加剂制造（AM）的进步使研究人员能够破译自然材料的复杂微观结构，并开发创新但可制造的，可制造的，可制造的，建筑的蜂窝材料。作为蜂窝材料的一个例子，在蝴蝶翼量表中发现的能型结构激发了这项研究项目，以开发构建的壳材料并通过AM制造它们。与晶格相反，由于其几何体系结构的不规则性而遭受应力浓度，壳材料具有光滑且连续的表面，使其成为具有高能量吸收能力的理想的高级轻质材料。由于三个周期性最小表面（TPM）的共面应力，构造的壳材料可以提供一类新的轻质拉伸主导的细胞固体，具有超高刚度和能量吸收特性。该项目的目的是采用AM技术来开发TPMS壳的高性能家族，并通过调整其几何特征并诉诸结构层次结构概念，从而使用优化的体系结构进行优化的体系结构。 Considering the enormous potential of architected shellular materials for developing lightweight load-bearing structural elements with energy absorbing and heat exchanging capabilities, Axis Prototypes (a leading Canadian 3D printing company that offers high-quality AM services) sponsors this research project and will directly collaborate with the McGill's research team to design, 3D print, and characterize architected shellular materials to introduce them as novel multifunctional materials for parts used in aerospace,汽车和能源部门。由于加拿大的3D印刷公司数量正在快速增长，因此该研究项目在发展中的先进制造行业和最先进的工程设计之间构成了桥梁，并为加拿大公司提供了一个很好的机会，成为高级轻量级材料制造领域的领导者。
