a Bright- and b dark-field reflective optical images of as-printed 3D mascot. c, e, g, i, k Bright- and d, f, h, j dark-field reflectance optical images of post-processed 3D mascots viewed from different angles. The 3D mascot lies on the receiving substrate in the front and back views. Back views were obtained by flipping the lying 3D mascot on the receiving substrate. The 3D mascot sat on the receiving substrate in the top view. l–p SEM images of post-processed 3D mascots viewed from different angles. Scale bars in a–m, o = 20 µm, scale bars in n, p = 5 µm.
