Mesostructure

Mesostructure… Is that a real word?

It sure is, and while the definitions are quite complex, the best way to understand a mesostructure is to look at some images of them. The top left photo is actually a nice 3D print of one you can download free from Thingiverse, and if you’re after something to show people the interesting things that can be 3D printed, this is a great example. I’ve printed them in ABS plastic, but the structure itself is both rigid and flexible. 3D modeling them can be a good little challenge – hopefully whatever CAD program you’re using has some great patterning and mirroring tools! I used Solidworks and really made the most of the parametric functions to allow quick and easy changes in the future. By changing the density of the structure, or simply increasing the thickness of them, you can really play around with the flexibility of the structure.

The other 2 images are actually my first little attempt and having a functional use for a mesostructure. I’m trying to isolate some small vibration motors, and this was one of the ideas building upon a previous round of prototypes that I’ve posted. It’s just like building in some springs between each motor. Nice and flexible and only 25 minutes to 3D print on my Cocoon Create, which is great when you’re trying to test and iterate multiple ideas quickly. Below is the 3D model for you to spin around.
