Building Porous Fungi structure grasshopper

[Karo]

Hi! I am industrial design student trying Grasshopper for some time but i find it quite hard when it comes to achiving structure in the photo below.

I’m trying to make a porous structure where I can change the pore sizes and also density. I want to design basic structure can be in further process applied to any shape. I came across article about building foam structures:

https://pubs.acs.org/doi/10.1021/acsbiomaterials.7b00916

Maybe this can be a way to achive it but I am quite stuck. I would really appreciate some help with this!

Thank you and waiting for some tips!!

Hello
you will find many many example of structure like the one in the paper. In old Grasshopper3d

voronoi generation in a cylinder

bone microstructure and voronoi diagram... need help

How to make bone-like with density?

Hey dear friends… I would like to know how to make the attached (geometry photo) as solid !or with density for 3D printing ? It would be appreciated if some one could help me! Best regards Ali [bone like 2]

Bone structure

hello everyone, I have an idea, I’ve been trying it out for a long time, but unfortunately I can’t manage it. I hope someone can help me with that: a bone-like structure is to be created, which is to be created with the help of stress lines and attractor.(?) the first step i would do with tOpos, and for the inner structure i need your help i.e. where the pressure or pull is the most, the structure should be denser, like a human bone. I hope I’ve described it well many thanks again to all …

Organic bone-like shapes problem

Hi @yotamcdo One issue with taking the curves from a Voronoi diagram of random points is that it usually has some very tiny edges and sharp angles, this is what was causing those funny looking nodes. [image] If you run some cleanup on the lines to get rid of these it is often enough to make it work: multipipe_fix.gh (16.3 KB) (also uses this tool Topologizer.gha (19 KB) ) [image]

but this seems not really like your image. If you really want to make it you’ll have to work a bit more on the key characteristic of this structure. Is it open structure (a fluid can go every where) a closed cell …
I recently helped on this

This pattern, can it be realized with GH? What's the best way to do it

Great I will look into it! Thank you!

so I’m back with getting more assistance in this. I saw your last script, but unfortunately Dendro doesn’t work on Mac, but from the screenshots it kinda look similar to what I want. I also tried with voronoi but it’s not possible to achieve an interwoven structure with it (or is it?) .

Here is the basic script with voronoi:

Any adivce would be much appreciated!
