The module aims at acquainting the participants with the basics of the ray-tracing program package “Blender”. This allows for two aspects relevant in the Cluster “3D Matter Made to Order”. First, you can make cool 3D graphics for publications and presentations yourself. For example, 3D architectures that have been 3D printed can be visualized. Second, the architectures defined by “Blender” can be exported in *.stl file format – the standard data format for 3D printing, including the Nanoscribe instrumentation available to all Cluster members in the KIT Nanostructure Service Laboratory. You can watch short introductions to this module by Young Scientists Pascal Kiefer and Jannis Weinacker here and here.
