Polycount doesn't really matter in 3D printing.
You're object is rendered to a file called an STL which kind of makes a series of math based slices.

Kind of like a series of illutrator or photoshop paths for each slice.

So you can have as many slices as you want.

The more relevent problem is, how water tight is you model.

I spend a good amount of time fixing some freebies where the creator decided to go with unwelded points rather than a modeled bevel for a hard edge. That won't fly in 3D print.

Subdividing is easy, but welding hundreds of points is a nightmare.

I haven't even introduced the concept of infill and skinning to save material costs.
