Benzene molecule model

pinshape

Here is a ball-and-stick model of benzene molecule. As you can see, carbon atoms (black) are linked using two connections which represent chemical bonds. It was printed with a gypsum powder printer at the Technical University of Berlin during a summer course. I designed it this way to better represent the resonance effect and make it less fragile since a gypsum model this thin will easily break if you're not careful. The size of atoms and the distance between them take into account chemistry bond theory. The scale is approximately 250,000,000 : 1. Post-Printing After the print is done, we have to clean the remaining powder from its surface and then infuse it with resin to make it less fragile. How I Designed This I used Autodesk Inventor for modeling and Autodesk Netfabb to check if the part was printable.
