Nomad for 3D printing Topology Help

Tips, Tutorials and Help
1

Greetings!
This is my first Nomad project that I’m trying to 3D print. But Im having issues keeping very sharp edges to color and print on my multi color printer.

I have looked up many guides on the best way to keep details when combining objects but when I try to print it on my Bambu Labs printer, it printer terribly.

I sculpted all the pieces separately then tried to combine them with the following methods:

  1. Voxel Remesh high for details > Then boolean > Quad Remesh @ 100% for better topology
  2. Voxel Remesh to combine very high > Then Decimate at around 10% to lower the polygons
  3. A mix of Voxel and Boolean > Then Quad Remesh and Decimate
  4. A mix of Voxel and Boolean > Then straight to the printer

All seemed to yield not the greatest edges for the 3D printer to recognize… I head that some people export it to another program like Blender or Zbrush, but I’m hoping to not have to open that can of worms haha

Here is what it looks like in the 3D printing software post slicing

Voxel remedying will mess it up because the lines won’t be as sharp and straight.

Here’s what I do:

  • keep all color parts separate
  • when my sculpt is done, I decimate each part individually
  • Once decimated, Boolean two parts at a time until everything is joined

This should keep your lines and color straight.

If it looks good in Nomad but bad in the slicer then the issue is with the slicer.

Maybe you can try baking into a texture in Nomad, in case the Bambu slicer accepts textures. I might work better than vertex color.

In case it looks bad in Nomad then the issue is with your method:
You don’t need to voxel before doing a Boolean (unless the Boolean fails). Voxel remesh is a lossy operation.

  1. In that case you want to bake into a texture. Copy->boolean->quad remesh->bake
  2. It should work fine but make sure to check the “paint” option in the decimator. It will decimate less on the paint edges

Okay I tried it but it still came out kind of strange. Do I also Quad Remesher after?

I never though about that first part! But that actually would make sense. It could be a Slicer issue for sure!

I will try bake it and see how that goes! Thank you for the suggestion!

No, I don’t use the quad remesher for it. Just Boolean the decimated parts.

I would check your paint lines in Bambu Studio and see what they look like. If anything goes weird with paint, I just import a .stl and manually paint using the bucket tool. Then I set the crease angle accordingly and am able to quickly paint it without issues.
