... to keep the same t throughout the pattern when the unit cell is linearly repeated. Figure 2 Re-entrant honeycomb cellular solid Definition of re-entrant honeycomb samples Additive manufacturing Cellular materials Mechanical metamaterials Compression test Compression...

... and introduces anisotropic weaknesses due to poor layer-to-layer adhesion. Curved-layer manufacturing has been gaining attention recently, with increasing potential to fabricate complex, low-weight structures, such as mechanical metamaterials. This paper aims to study the fabrication and mechanical...
