Close-Ups of Nanostructures (IMAGE) Graz University of Technology Caption Examples from the three-dimensional printed nanoworld show the complexity (a), the achievable structure sizes (b) as well as the path from meshed towards closed 3D surfaces (c). All images are re-coloured scanning electron microscope micrographs with a 500 nm wide scale bar.
