Figure 4

DIW 3D printed dual pore scaffold aerogel in a 0–90° configuration for (a) a cube and (b) a nose model. (c) The corresponding SEM images illustrate an average structural pore size of about 600 µm (green box) and a random pore size distribution of 20 to 800 µm (red box). 20 wt% CNC gel and 500 µm nozzle tip was used. Unless specified, displayed scale bars are 1 cm.
