Low Poly designs?

recently i have created a few characters for a game project i was working on, so i thought about having them printed.

Though because of that im trying to print the ingame assets directly im having some pretty lowpoly models.

so i was wondering, does anyone have experience with printing lowpoly models and how will those turn out.

will they look as faceted as in the preview or will it smooth out a little. Also what are the options of sanding the models with sandpaper to obtain a smoother look. (probably the WSF material)

here's an example: https://www.shapeways.com/model/583507/45b49dfaea64f329698d2f b7f1fbc76d

Depending on the material it will smooth out a little - but not enough to cloud that the model is THAT low poly.

In my opinion, that's a waste of time
since Shapeways also offers polished WSF.
