Lattice structures are ubiquitous: from the regular arrangement of hexagonal cells in the brood of a honey bee to roof trusses and gas turbine blades. They are all characterized by a unit that repeats itself either linearly or cyclically in one, two, or three-dimensions. The notion of micro-architectured metallic truss lattice materials has received wide interest among the mechanics of materials community over the past five years. Central to these efforts is the goal to achieve tailored lattice architectures with high specific stiffness and strength in all metallic and composite structures. Such structures have applications in aerospace and automotive industries. Today, engineers are in a position to 'write' complex three dimensional lattice patterns in a computer which will be translated to a manufactured component, thanks to modern manufacturing techniques such as laser micromachining, micro printing, and soft lithography. This is possible due to the developments in microelectronics industry.

格子结构无处不在：从蜜蜂窝中规则排列的六边形细胞到屋顶桁架和燃气涡轮机叶片。它们都以一个单元为特征，该单元在一维、二维或三维中线性或循环地重复自身。微结构金属桁架晶格材料的概念在过去的五年中受到材料力学界的广泛关注。这些努力的核心是在所有金属和复合材料结构中实现具有高比刚度和强度的定制晶格结构。这种结构在航空航天和汽车工业中有应用。今天，工程师能够在计算机中“编写”复杂的三维晶格图案，这些图案将被翻译成制造的组件，这要归功于现代制造技术，如激光微加工，微印刷和软光刻。由于微电子工业的发展，这是可能的。
