Surface finish and accuracy

Hello All,

First post here and very new to the world of 3dprinting...
I'm looking at the possibilities of using 3d printing for the manufacture of some components (approx size 500mm x 200mm x 200mm) using an FDM printer (which I haven't aquired yet, so I'm open to suggestions for the ideal printer for this job!).
My question is regarding the repeatability / accuracy of the prints...due to the fact that I am having to make this component in two parts (internal access is required for other componentry), is it feasible to produce the two halves of the shell and expect them to mate accurately? Or, is it more likely that I will have to produce two halves with thickened edges and sand the outer edges and mating faces to get a good join?

Any help and suggestions gratefully recieved...
