I don’t know which printer you use, but as you say SLA this means that you want to print a hollow shape with only one skin.
If you disjoin the mesh you will see 2 meshes (inside and outside).

Hello
it is also hard for me to understand.

Is the mesh invalid in Rhino or at the printer level ?
If it is in Rhino, there are some “chances” that it is due to the Mesh Thicken component. For such jobs it seems better to rely on Dendro (it has the power of OpenVdB) or to rely on specific software to thicken the mesh. MeshMixer has some fonctionality.


If you want some help with Dendro
Make a GH file with only the mesh (internalize it with a Mesh component) you want to thicken/shell.
Then draw what you want. I understand a solid with 1 mm thick shell.
Do you have documentation on you 3d printer ?

how i internalize it with a Mesh component ?

Keep in Rhino if you want. Right click on a geometry component, you will see “internalize”.
