Researchers from the Institute of Material Science in Barcelona have released a tutorial on how to 3D print an microscopic image.
The Atomic Force Microscopy (AFM) is a very high-resolution type of scanning probe microscopy on a nanometer scale. Applying this technique the researchers can get precise 3D surfaces of materials.
For their tutorial they used a 20 x 20 microns AFM image of hydrogel, which is then exported as STL file. After opening it in the 3D modelling software Blender, it can be rescaled to a larger size and further edited. Once this process has been completed, the file just needs to be sent to Slic3r before final 3D printing the structure. The detailed tutorial can be read here.
