The present invention relates generally to methods of fabricating surface topography based on a scanned surface topography. The method converts 3D scanned surface topography data that have submicron resolution to digital formats that can be stored, manipulated, or tiled, and used as an input for replicating the surface topography with submicron resolution on another substrate. The digitized surface topography data is then converted to input for 1) 3D printing to replicate the scanned surface topography with submicron resolution, with or without a subsequent coating layer or layers to impart additional properties and/or features, 2) 3D printing a master that replicates the scanned surface topography with submicron resolution, which will be used for fast replica molding of the surface topography onto another substrate, and 3) creating a photomask with submicron resolution for transferring the surface topography to a metal substrate surface through subsequent photolithography and etching processes.
