Matte Surface on the actual surface

Hi all,

I need to make a matte surface in the acutal closed polysurface to make a prototype(still looking at options what 3D printer to use for such detail)

In anycase, the material will likely be TPU and would like to reduce the surface friction without putting extra coating on it.

Anyway to add such a matte surface bumps to the actual surface?(The surface itself is just like a half sphere but squished.)

I can array small dots project it down to the closed half sphere and make a small sphere with each dots and boolean those million dots from the closed half sphere, but that doesn’t seem so smart…

Hello- ApplyDisplacement, then ExtractRenderMesh (to export) might do it.
