Was that one done on a cheap 3D printer?
that looks to be .1mm accuracy on a normal extruder based 3D printer, those printers range from $500 to $2500 (or at least the few i've looked at)
Some ways to improve accuracy would be to use the UV reactive material, those get pretty good resolution, and cost $500 to $2300 up, but the material to print is super expensive (I can't find exacts) but a decent UV printer can get layer accuracy of .025.
One thing that could be done to finish the part, would be to run it through an "acetone-steam-bath" type thing, that would give it a nice smooth glossy finish
