Since broad temperature range electromagnetic attenuation materials and structures are conventionally manufactured based on ceramic-based materials and composites, an alternative strategy is developed here to construct metal electromagnetic metastructures based on triangulated cylindrical origami design and metal 3D printing technology. The experimental and simulated results suggest that the as-manufactured 3D-printed metal origami metastructures enable to effectively scatter electromagnetic wave, resulting in effective low reflectivity stably over a broad temperature range of 20-800 degrees C. Implication of the discussion on mechanism, materials, processing, and performance suggests a novel platform for achieving metallic electromagnetic metastructures and metastructures for broad temperature range stealth technology.
