Abstract
This study investigates the influence of elementary cell topology on the bending behaviour of the 3D printed sandwich beams. Three distinct designs for the cell topologies (Schwarz P, Star and Octet) were fabricated using UV-curable resin and tested under three-point bending conditions. The results indicated that the use of the cell topology Schwarz P gave the highest force resistance and bending stiffness, while the Star design provided a balanced compromise between strength and deformation. In contrast, the Octet-based beam exhibited gradual failure, suggesting its potential for the vibration energy harvest-ing in micro- and meso-scale.
