Highlights

• Multifunctional lightweight seamless meta-sandwich composite (MMSC) is devised.

• Broadband electromagnetic wave absorption is achieved with load-bearing capability.

• Single-step multi-material 3D printing manufactures MMSC using octet-truss core.

• Optimized upper-lower faceplatetes as transmitting-reflecting layers thin the MMSC.

• High absorption rate-low broadband reflection loss is obtained in target bandwidth.
