Microstructures of bioinspired platelet-epoxy composites produced via robocasting of platelet pastes and comparison to natural analogues. (a,b,c) Schematic diagrams of the three morphologies (trans-filament, inter-filament and Bouligand) produced by controlling the printing direction, with fracture direction indicated. (d,e,f) SEM images of fracture surfaces of the three composites, infiltrated with epoxy. Scale bars 400 μm. (g) Photograph of composite parts produced from arbitrary CAD files to demonstrate the flexibility of the technique. (h) SEM images showing the microstructure of the printed part. Scale bars 10 and 500 μm.
