I know this thread is rather old, but I thought before opening a new one I might as well just use this one, because I have the same kind of problem.
I am modelling a piece of jewellery which my girlfriend wants to print with a wax printer (she’s a gold smith).
I already know that I have to check if the model is manifold (have done that, and it is).
But there are still two specific questions left, which I want to ask before I give her the .stl-file:
- The mesh has a ring shape. I am sure that the printer (I guess not even the .stl-format itself) knows what a subsurf modifier, an edge split modifier or Blender’s “smoothing” is. So how can I get a really smooth ring in the end?
Do I just need to make it with enough vertices, so you can’t see the edges anymore? And if so? Does anybody have an idea how many vertices I would need for a ring with a 9 mm radius?
2.) How do the blender units translate into the printer’s units? I have modelled the ring using 1 blender unit = 1 mm. Do they have to set that in the printer software? Or is there a certain value? Or how else does it work?
I would be really happy, if somebody could help me with that.
Thanks a lot!
