美国劳伦斯·利弗莫尔国家实验室和麻省理工学院近期对外宣布,已通过微型增材制造(3D打印)技术——面投影微立体光刻技术,开发了一种超轻型新材料,该材料承重量可达到自身重量的16万倍,在重量和密度相当情况下,刚度是气凝胶材料的1万倍。研究人员通过在聚合物、金属、陶瓷等材料上涂覆(金属、陶瓷等)薄膜涂层,其芯模通过加热方法去除,留下中空管状结构,通过重复上述工艺过程制造管状结构,从而形成超轻、超高刚度金属晶格材料。该项目由美国预先研究计划局(DARpA)和劳伦斯·利弗莫
The Lawrence Livermore National Laboratory and the Massachusetts Institute of Technology recently announced that they have developed an ultra-light new material through micro-additive manufacturing (3D printing) technology, surface-projection microlithography Material bearing capacity of up to 160,000 times its own weight, in the case of weight and density, the stiffness is 10,000 times the airgel material. The researchers coated the polymer, metal, ceramic and other materials (metal, ceramic, etc.) film coating, the core mold is removed by heating, leaving the hollow tubular structure, by repeating the above process to create a tubular structure, thereby forming Ultra-light, ultra-high stiffness metallic lattice material. The project is funded by the DARpA and Lawrence Livermore
