can anyone provide me with the keywords necessary to figure out what process is

can anyone provide me with the keywords necessary to figure out what process is used to make 3D models like these? I’ve tried “organic”, “porous”, and a couple of others. I’m just wondering if there is a tool like Meshmixer that can post-process a solid model to give it a random porous look.

Voronoi

Lace?

A quick search on “voronoi 3d” found this:

@Alan_Thomason wow, very cool, thank you!

@Dave_M Not a problem, sometimes the right keyword is all you need.

In the instructable comments, there’s a great site called http://voronator.com that does a great job on small parts!

Meshmixer does a good job of making voronoi versions of solids, but the documentation isn’t great. I struggled quite a bit in trying to get a decent workflow together for producing voronoi meshes from surfaces.
