摘　　要：增材制造技术解除了传统制造方法对零件结构的限制,使越来越多复杂结构的“自由制造”成为可能。超材料的出现打破了自然界传统结构在性能上的限制,实现了许多自然结构无法实现的功能。随着增材制造技术的日益成熟,对于高性能、轻量化构件的需求愈来愈强烈,而超材料在具有自然结构所不具备的超常物理性质前提下,进一步实现了超强超轻的机械目标。增材制造的技术特点消除了超材料的制造约束,提高了超材料的潜力,为结构复杂的机械超材料的成型提供了一种有效的方法。零泊松比结构是一种特殊的机械超材料,它优异的性能引起人们的广泛关注。总结了目前国内外增材制造技术成型机械超材料的相关研究进展和激光选区熔化成型具有零泊松比特性的板壳晶格结构的设计难点,并对其发展进行了展望。Additive manufacturing technology removes the limitations of traditional manufacturing methods for components structure,making more and more“free manufacturing”of complex structures possible.The emergence of meta-materials breaks the performance limitations of traditional nature structures and achieves many functions that natural structures cannot achieve.With the increasing maturity of additive manufacturing technology,the demand for high performance and lightweight components is more and more intense,while the meta-material further realizes the mechanical goal of super strong and ultralight with the extraordinary physical properties that natural structure does not have.The technical features of additive manufacturing eliminate the manufacturing constraints of meta-materials,improve the potential of meta-materials,and provide an effective method for complex formation of mechanical meta-material.The zero poisson ratio structure is a special mechanical meta-material that attracts wide attention due to its excellent properties.The current research progress for mechanical meta-materials of additive manufacturing technology modeling at home and abroad and the design difficulties of plate-shell structure with zero poisson ratio modeled by selective laser melting were summarized,and its development was prospected.
