3D print from 3D voronoi with cells, can't union pipes and cells

I’m not sure if i should put this under grasshopper or rhino so sorry if u see this twice!

I’m trying to create a 3d voronoi inside a certain geometry, I want to create a frame of tubes with a certain thickness, but with grasshopper it creates all seperate closed polysurfaces. I cant boolean union it, but i want to make it 1 object instead off 2000 polysurfaces so I can 3d print it.

I also want some cells still in it and a frame around it (like in the screenshot). I baked the pipes for the tubes and the solid intesection for the different cells, the frame around the geometry is 1 polysurface i made manually. All of this should be 1 object to 3d print, but right now i can’t boolean union all of this.

Do you guys know how to clean this up? Or how i can make a 3d print mesh out of this?

i’ll put my GH file and my geometry to start with in this post, toghether with a picture of what i want to 3d print.

thank you!!

What 3d printing service/software are you using?
Many of them can handle overlapping solids as long as each of them is closed, so you might not even need to boolean it in Rhino.

Well i heard this before, but i’m a student and part of my task is to make 1 closed polysurface :confused:

Hello - the parts in your file Union just fine but do not match the object in the image.



No, i want to use my gh file on te geometry inside of the frame, that way i get the object in the image, but the voronoi consists out of a lot of different pipes i want to union

this is the geometry i want to use as brep
