Fig. 4
In situ uniaxial compression of 3D printed nickel octet nanolattices. a–d SEM images of the nickel structure during the compression test a before full contact, b in the elastic regime, c during layer-by-layer collapse, and d during densification. e Stress–strain data for compression of four nickel nanolattices. Letters on the graph correspond to the regions represented by a–d. f Specific strength-beam size plot showing properties of nickel nanolattices compared to other metal lattices fabricated using selective laser melting (SLM), direct metal laser sintering (DMLS), electron beam melting (EBM), and ink-based methods. See Supplementary Table 2 for data and references. Scale bars are 5 μm for a–d
