As a matter of fact, most natural structures are complex topology structures with intricate holes or irregular surface morphology. These structures can be used as lightweight infill, porous scaffold, energy absorber or micro-reactor. With the rapid advancement of 3D printing, the complex topology structures can now be efficiently and accurately fabricated by stacking layered materials. The novel manufacturing technology and application background put forward new demands and challenges to the current design methodologies of complex topology structures. In this paper, a brief review on the development of recent complex topology structure design methods was provided; meanwhile, the limitations of existing methods and future work are also discussed in the end.
事实上，大多数天然结构都是具有复杂孔洞或不规则表面形态的复杂拓扑结构。这些结构可用作轻质填充物、多孔支架、能量吸收器或微反应器。随着3D打印技术的飞速发展，现在可以通过堆叠层状材料高效、精确地制造复杂拓扑结构。这种新颖的制造技术和应用背景对当前复杂拓扑结构的设计方法提出了新的要求和挑战。本文简要回顾了近期复杂拓扑结构设计方法的发展；同时，最后也讨论了现有方法的局限性和未来的工作。
