What is the limitation of Rapid Prototyping in terms of cavity size?

I would like to build a few 14mm diameter plastic disks with a hole in the centre. I would like to know how small the hole diameter can go if I build the disks using rapid prototyping e.g. 1mm, 100 microns etc. Thank you.

1. In standard resolution, the minimum feature in the X-Y plane is 0.010" and the minimum in the Z axis is 0.016". In high resolution, the 0.003" laser beam spot enables smaller features. ProtoCAM recommends a minimum wall thickness of 0.020" for prototype support.
