Fine detail is a jet printing process. I believe the jet printers Shapeways is using are 600 x 600 DPI X & Y, and at 16 microns per layer the Z is 1600 DPI. (3D Systems has 750 x 750 DPI machines with 13 micron layer capability, and 1600 x 900 but only for 32 micron layers.) 
If these don't sound like very high resolution printers, remember that there are two jet nozzels per pixel - you can place either wax or body material at each location.
