During this week the FabLab was closed, this meant i couldn’t do any 3D printing. I took this as a time to model my concepts in Rhino and to try further my grasshopper practice.
After playing around for a while i was finally able to get a 3D voronoi to fill in a custom sole shape that I created. I was able to pull some renders of how these concepts developed. I am able to change the density of the voronoi and also control the thickness. However when exporting to rhino the structure still is made of thousands of seperate polysurfaces meaning it will need more work if i wish to 3D print these models.
Showing a range of voronoi structures with foam poured inside. Next i will be using grasshopper along with digital scans of foot pressure and attempt to match the density of voronoi to the high areas of force exerted by the foot.
This is an example where i manually add in points around the foot that directs the voronoi structure away from these areas in 2D.
