Hi,
V8.
take an object created in Rhino (V5 then opened in v8)
export it as a .3mf, the new kid on the block when it comes to 3D printing preferred files.
Open that file in rendered mode, also shaded, also artistic, seeking a view that doesnt baffle the eyes.
then import the stp export of it, much more as per the original surfaces.
3mf is a mess !

Can you post all these files?
Kind of what I expect to see, although 3MF is very poorly rendered - almost to the point of being visually unusable. The 3MF geometry seems fine when imported into a slicer.
SHADED VIEW:
ARTISTIC:
Note that the visual appearance of the 3MF file indicates that the mesh has a topology where exactly one vertex equals one corner.
Look at the number of vertices in each of the two files:
For example, the selected point has 3 vertices in the topology, which explains the difference between 466 and 1516, and, in simple terms, explains why the rendering is different.
If you use the ExtractMeshPart command on the STL, you will see that you can extract the faces individually, whereas on the 3MF file, you cannot.
note:
If you use the UnWeld command on the 3MF file, you will get a result comparable to the STL.
If you use the weld command on the STL file, you will get a result comparable to the 3MF.
This particularity affects the rendering but has no impact on the geometry.
The STL file allows for a nicer rendering but with larger files.
The 3MF file focuses solely on the geometry and can have smaller files.
